WARNING
LOSS OF CONTROL
The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart.
Separate or redundant control paths must be provided for critical control functions.
System control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link.
Observe all accident prevention regulations and local safety guidelines.

Flash Memory Organization
Introduction
The Flash memory contains the file system used by the controller.
The total size of the Flash memory is 128 MB, of which 10 MB is available for the application.
File Type
The Modicon M258 Logic Controller manages the following file types:
Type Description
Executable application User application. This is the binary code that is executed when the controller is in the RUNNING state.
Boot application This file resides in Flash memory and contains the compiled binary code of the executable application. Each time the controller is rebooted, the executable application is extracted from the boot application and copied into the controller
RAM (1) .
Application source
Post configuration
Source file that can be uploaded from Flash memory to the PC if the source file is not available on the PC (2) .
File that contains Ethernet, serial line, and firewall parameters.
The parameters specified in the file override the parameters in the executable application at each reboot.
Data logging
HTML page
Files in which the controller logs events as specified by the application.
HTML pages displayed by the web server for the website embedded in the controller.
Operating System (OS) Controller firmware that can be written to Flash memory. The firmware file is applied at next reboot of the controller.
Retain variable Remanent variables
Retain-persistent variable
(1) The creation of a boot application is optional in EcoStruxure Machine Expert, according to application properties. Default option is to create the boot application on download. When you download an application from EcoStruxure Machine Expert to the controller, you are transferring only the binary executable application directly to RAM.
(2) EcoStruxure Machine Expert does not support uploading of either the executable application or the boot application to a PC for modification. Program modifications must be made to the application source. When you download your application, you have the option to store the source file to Flash memory.
28
EIO0000004135 09/2020
Memory Mapping
There are two ways to create the boot application:
Select the option during the application download process.
Choose Online → Create boot application at any point after download.
If you do not create a boot application, the controller will enter the EMPTY state after the next reboot.

EIO0000004135 09/2020
Memory Mapping
Files Redirection
When system, program or certain user activity creates specific file types, the M258 Logic Controller examines the file extension and automatically moves the file to a corresponding folder in flash memory.
The following table lists the file types that are moved in this way and the destination folder in flash memory:
File extensions
*.app, *.ap_, *.err, *.crc, *.frc, *.prj
*.cfg, *.cf_
*.log
*.rcp, *.rsi
Flash memory folder
/usr/App
/usr/Cfg
/usr/Log
/usr/Rcp
Backup Data Logging File
Data logging files can become quite large to the point of exceeding the space available in the file system. You should, therefore, develop a method to periodically archive the log data on a USB key.
For example, you could split the log data into several files, e.g. LogMonth1, LogMonth2 , and use the ExecuteScript command (refer to the Modicon M258 Logic Controller PLC System
Functions and Variables PLCSystem Library Guide) to copy the first file to a USB key, and thereafter, remove it from the internal file system while the second file is accumulating data. If you allow the data logging file to grow and exceed the limits of the file size, you could lose data
NOTICE
LOSS OF DATA
Back up your *.log files to a USB key on a regular schedule that avoids saturating the available free space in your controller file system.
Failure to follow these instructions can result in equipment damage.

Relocation Table
Introduction
The Relocation Table allows you to organize data to optimize communication between the controller and other equipment by regrouping non-contiguous data into a contiguous table of located registers, accessible through Modbus.
NOTE: A relocation table is considered an object. Only one relocation table object can be added to a controller.

Tasks
Introduction
The Task Configuration node in the Applications tree allows you to define one or more tasks to control the execution of your application program.
The task types available are:
Cyclic
Freewheeling
Event
External event
This chapter begins with an explanation of these task types and provides information regarding the maximum number of tasks, the default task configuration, and task prioritization. In addition, this chapter introduces the system and task watchdog functions and explains its relationship to task execution.

Tasks
Maximum Number of Tasks
Maximum Number of Tasks
The maximum number of tasks you can define for the Modicon M258 Logic Controller are:
Total number of tasks = 20
Cyclic tasks = 4
Freewheeling tasks = 1
Event tasks = 8
External Event tasks = 8
Special Considerations for Freewheeling
A Freewheeling task
( see page 40 ) does not have a fixed duration. In Freewheeling mode, each
task scan starts when the previous scan has been completed and after a period of system processing (30% of the total duration of the Freewheeling task). If the system processing period is reduced to less than 15% for more than 3 seconds due to interruptions by other tasks, a system error is detected. For more information, refer to the System Watchdog
NOTE: You may wish to avoid using a Freewheeling task in a multi-task application when some high priority and time-consuming tasks are running. Doing so may provoke a task Watchdog
Timeout. You should not assign CANopen to a freewheeling task. CANopen should be assigned to a cyclic task.

The table describes the fields of the Configuration screen:
Field Name
Priority
Type
Watchdog
POUs
Definition
Configure the priority of each task with a number from 0 to 31 (0 is the highest priority, 31 is the lowest).
Only one task at a time can be running. The priority determines when the task runs:
A higher priority task pre-empts a lower priority task
Tasks with same priority run in turn (2 ms time-slice)
NOTE: Do not assign tasks with the same priority. If there are yet other tasks that attempt to pre-empt tasks with the same priority, the result could be indeterminate and unpredicable.
For important safety information, refer to Task Priorities ( see page 43 ) .
These task types are available:
Cyclic
Event
Freewheeling
( see page 42 ) , define these two parameters:
Time: enter the timeout before watchdog execution.
Sensitivity: defines the number of expirations of the watchdog timer before the controller stops program execution and enters a HALT state
The list of POUs (Programming Organization Units) controlled by the task is defined in the task configuration window:
To add a POU linked to the task, use the command Add Call and select the POU in the
Input Assistant editor.
To remove a POU from the list, use the command Remove Call.
To replace the currently selected POU of the list by another one, use the command
Change Call.
POUs are executed in the order shown in the list. To move the POUs in the list, select a
POU and use the command Move Up or Move Down.
NOTE: You can create as many POUs as you want. An application with several small
POUs, as opposed to one large POU, can improve the refresh time of the variables in online mode.

Tasks
Task Types
Introduction
The following section describes the various task types available for your program, along with a description of the task type characteristics.
Cyclic Task
A Cyclic task is assigned a fixed cycle time using the Interval setting in the Type section of
Configuration subtab for that task. Each Cyclic task type executes as follows:
1. Read Inputs: The physical input states are written to the %I input memory variables and other system operations are executed.
2. Task Processing: The user code (POU, and so on) defined in the task is processed. The %Q output memory variables are updated according to your application program instructions but not yet written to the physical outputs during this operation.
3. Write Outputs: The %Q output memory variables are modified with any output forcing that has been defined; however, the writing of the physical outputs depends upon the type of output and instructions used.
For more information on defining the bus cycle task, refer to the EcoStruxure Machine Expert
Programming Guide and Modicon M258 Logic Controller Settings ( see page 76 )
.
For more information on I/O behavior, refer to Controller States Detailed Description
4. Remaining Interval time: The controller firmware carries out system processing and any other lower priority tasks.
NOTE: If you define too short a period for a cyclic task, it will repeat immediately after the write of the outputs and without executing other lower priority tasks or any system processing. This will affect the execution of all tasks and cause the controller to exceed the system watchdog limits, generating a system watchdog exception.

Tasks
Freewheeling Task
A Freewheeling task does not have a fixed duration. In Freewheeling mode, each task scan begins when the previous scan has been completed and after a short period of system processing. Each
Freewheeling task type executes as follows:
1. Read Inputs: The physical input states are written to the %I input memory variables and other system operations are executed.
2. Task Processing: The user code (POU, and so on) defined in the task is processed. The %Q output memory variables are updated according to your application program instructions but not yet written to the physical outputs during this operation.
3. Write Outputs: The %Q output memory variables are modified with any output forcing that has been defined; however, the writing of the physical outputs depends upon the type of output and instructions used.
For more information on defining the bus cycle task, refer to the EcoStruxure Machine Expert
Programming Guide and Modicon M258 Logic Controller Settings ( see page 76 )
.
For more information on I/O behavior, refer to Controller States Detailed Description
4. System Processing: The controller firmware carries out system processing and any other lower priority tasks (for example: HTTP management, Ethernet management, parameters management).
NOTE: If you want to define the task interval, refer to Cyclic Task ( see page 39 )

Tasks
Event Task
This type of task is event-driven and is initiated by a program variable. It starts at the rising edge of the boolean variable associated to the trigger event unless pre-empted by a higher priority task.
In that case, the Event task will start as dictated by the task priority assignments.
For example, if you have defined a variable called my_Var and would like to assign it to an Event, proceed as follows:
Step Action
1 Double-click the TASK in the Applications tree.
2 Select Event from the Type list in the Configuration tab.
3
Click the Input Assistant button to the right of the Event field.
Result: The Input Assistant window appears.
4 Navigate in the tree of the Input Assistant dialog box to find and assign the my_Var variable.
NOTE: The maximum frequency admissible for the event triggering an Event task is 100 Hz.
External Event Task
This type of task is event-driven and is initiated by the detection of a hardware or hardware-related function event. It starts when the event occurs unless pre-empted by a higher priority task. In that case, the External Event task will start as dictated by the task priority assignments.
For example, an External event task could be associated with an HSC Stop event. To associate the BLOCK0_HSCSTOP event to an External event task, select it from the External event dropdown list on the Configuration tab.
Depending on the controller, there are up to 4 types of events that can be associated with an
External event task:
Rising edge on an advanced input ( DI0 ...
DI7 )
HSC thresholds
HSC Stop
CAN Sync
NOTE: CAN Sync is a specific event object, dependent on the CANopen manager configuration.
When the Sync Generation is enabled in the CANopen Manager, an associated CANx_Sync task is automatically created in the task configuration.
NOTE: The maximum frequency admissible for an event triggering an Event task is 100 Hz.

Tasks
System and Task Watchdogs
Introduction
Two types of watchdog functionality are implemented for the Modicon M258 Logic Controller:
System Watchdogs: These watchdogs are defined in and managed by the controller firmware.
These are not configurable by the user.
Task Watchdogs: These watchdogs are optional watchdogs that you can define for each task.
These are managed by your application program and are configurable in EcoStruxure Machine
Expert.
System Watchdogs
Three system watchdogs are defined for the Modicon M258 Logic Controller. They are managed by the controller firmware and are therefore sometimes referred to as hardware watchdogs in the
EcoStruxure Machine Expert online help. When one of the system watchdogs exceeds its threshold conditions, an error is detected.
The threshold conditions for the 3 system watchdogs are defined as follows:
If all of the tasks require more than 85% of the processor resources for more than 3 seconds, a
system error is detected. The controller enters the HALT state.
If the total execution time of the tasks with priorities between 0 and 24 reaches 100% of processor resources for more than 1 second, an application error is detected. The controller responds with an automatic reboot into the EMPTY state.
If the lowest priority task of the system is not executed during an interval of 10 seconds, a system error is detected. The controller responds with an automatic reboot into the EMPTY state.
NOTE: System watchdogs are not configurable by the user.
Task Watchdogs
EcoStruxure Machine Expert allows you to configure an optional task watchdog for every task defined in your application program. (Task watchdogs are sometimes also referred to as software watchdogs or control timers in the EcoStruxure Machine Expert online help). When one of your defined task watchdogs reaches its threshold condition, an application error is detected and the controller enters the HALT state.
When defining a task watchdog, the following options are available:
Time: This defines the allowable maximum execution time for a task. When a task takes longer
than this, the controller will report a task watchdog exception.
Sensitivity: The sensitivity field defines the number of task watchdog exceptions that must occur before the controller detects an application error.
To access the configuration of a task watchdog, double-click the Task in the Applications tree.
NOTE: For more information on watchdogs, refer to EcoStruxure Machine Expert Programming
Guide.

Tasks
Task Priorities
Task Priority Configuration
You can configure the priority of each task between 0 and 31 (0 is the highest priority, 31 is the lowest). Each task must have a unique priority. Assigning the same priority to more than one task leads to a build error.
Task Priority Suggestions
Priority 0 to 24: Controller tasks. Assign these priorities to tasks with a high availability requirement.
Priority 25 to 31: Background tasks. Assign these priorities to tasks with a low availability requirement.
EIO0000004135 09/2020
43
Tasks
Task Preemption Due to Task Priorities
When a task cycle starts, it can interrupt any task with lower priority (task preemption). The interrupted task resumes when the higher priority task cycle is finished.
44
NOTE: If the same input is used in different tasks the input image may change during the task cycle of the lower priority task.
To improve the likelihood of proper output behavior during multitasking, a message is displayed if outputs in the same byte are used in different tasks.
WARNING
UNINTENDED EQUIPMENT OPERATION
Map your inputs so that tasks do not alter the input images in an unexpected manner.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Tasks
Default Task Configuration
Default Task Configuration
For the Modicon M258 Logic Controller:
The MAST task can be configured in Freewheeling or Cyclic mode. The MAST task is
automatically created by default in Cyclic mode. Its preset priority is medium (15), its preset interval is 20 ms, and its task watchdog service is activated with a time of 100 ms and a
sensitivity of 1. Refer to Task Priorities
Refer to System and Task Watchdogs
) for more information on priority settings.
for more information on watchdogs.
A CANx_Sync task is created automatically when a CANopen Manager is added to the CANx
(CAN0 or CAN1) interface and configured with Sync Generation enabled. This task is declared as an External Event task, and reduces the number of External Event tasks you can configure for other operations by one. By default, the CANx_Sync task is assigned a priority of 2 (or 3 if another CANx_Sync task has already been created). This is appropriate for many installations, but it is your responsibility to verify the correct task priority setting for your system. Refer to Task
for more information.
Designing an efficient application program is important in systems approaching the maximum number of tasks. In such an application, it can be difficult to keep the resource utilization below the system watchdog threshold. If priority reassignments alone are not sufficient to remain below the threshold, some lower priority tasks can be made to use fewer system resources if the
SysTaskWaitSleep function, contained in the SysTask library, is added to those tasks.
NOTE: Do not delete or change the name of the MAST and CANx_Sync tasks. If you do so,
EcoStruxure Machine Expert detects an error when you attempt to build the application, and you are not able to download it to the controller.
NOTE: Do not change the Type or External Event attributes of CANx_Sync tasks. If you do so,
EcoStruxure Machine Expert will detect an error when you attempt to build the application, and you are not able to download it to the controller.

Note 1
The Power Cycle (Power Interruption followed by a Power ON) deletes all output forcing settings.
Refer to Controller State and Output Behavior ( see page 58 )
for further details.
Note 2
There is a 4-5 second delay between entering the BOOTING state and the LED indication of this state. The boot process can take up to 45 seconds under normal conditions. The outputs will assume their initialization states.
Note 3
In some cases, when a system error is detected, it will cause the controller to automatically reboot into the EMPTY state as if no Boot application were present in the Flash memory. However, the
Boot application is not actually deleted from the Flash memory.
Note 4
After verification of a valid Boot application the following events occur:
The application is loaded into RAM.
The Post Configuration
file settings (if any) are applied.
During the load of the boot application, a Check context test occurs to assure that the Remanent variables are valid. If the Check context test is invalid, the boot application will load but the controller will assume STOPPED state
Note 5a
The Starting Mode is set in the PLC settings tab of the Controller Device Editor.
Note 5b
When a power interruption occurs, the controller continues in the RUNNING state for at least 4 ms before shutting down. If you have configured and provide power to the Run/Stop input from the same source as the controller, the loss of power to this input will be detected immediately, and the controller will behave as if a STOP command was received. Therefore, if you provide power to the controller and the Run/Stop input from the same source, your controller will normally reboot into the STOPPED state after a power interruption when Starting Mode is set to Start as previous state.

Note 6
During a successful application download, the following events occur:
The application is loaded directly into RAM.
By default, the Boot application is created and saved into the Flash memory.
The Post Configuration
file settings (if any) are applied.
Note 7
The default behavior after downloading an application program is for the controller to enter the
STOPPED state irrespective of the Run/Stop input setting or the last controller state before the download.
However, there are two important considerations in this regard:
Online Change: An online change (partial download) initiated while the controller is in the
RUNNING state returns the controller to the RUNNING state if successful and provided the
Run/Stop input is configured and set to Run. Before using the Login with online change option, test the changes to your application program in a virtual or non-production environment and confirm that the controller and attached equipment assume their expected conditions in the
RUNNING state.
WARNING
UNINTENDED EQUIPMENT OPERATION
Always verify that online changes to a RUNNING application program operate as expected before downloading them to controllers.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: Online changes to your program are not automatically written to the Boot application, and will be overwritten by the existing Boot application at the next reboot. If you wish your changes to persist through a reboot, manually update the Boot application by selecting Create boot application in the Online menu (the controller must be in the STOPPED state to achieve this operation).

Controller States and Behaviors
Multiple Download: EcoStruxure Machine Expert has a feature that allows you to perform a full application download to multiple targets on your network or fieldbus. One of the default options when you select the Multiple Download... command is the Start all applications after download or online change option, which restarts all download targets in the RUNNING state, provided their respective Run/Stop inputs are commanding the RUNNING state, but irrespective of their last controller state before the multiple download was initiated. Deselect this option if you do not want all targeted controllers to restart in the RUNNING state. In addition, before using the
Multiple Download option, test the changes to your application program in a virtual or nonproduction environment and confirm that the targeted controllers and attached equipment assume their expected conditions in the RUNNING state.
WARNING
UNINTENDED EQUIPMENT OPERATION
Always verify that your application program will operate as expected for all targeted controllers and equipment before issuing the "Multiple Download…" command with the "Start all applications after download or online change" option selected.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: During a multiple download, unlike a normal download, EcoStruxure Machine Expert does not offer the option to create a Boot application. You can manually create a Boot application at any time by selecting Create boot application in the Online menu on all targeted controllers (the controller must be in the STOPPED state for this operation).
Note 8
The EcoStruxure Machine Expert software platform allows many powerful options for managing task execution and output conditions while the controller is in the STOPPED or HALT states. Refer
to Controller States Description ( see page 53 )
for further details.
Note 9
To exit the HALT state it is necessary to issue one of the Reset commands (Reset Warm, Reset
Cold, Reset Origin), download an application or cycle power.
In case of non recoverable event (system watchdog or internal error), a cycle power is mandatory.
Note 10
The RUNNING state has two exception conditions.
They are:
RUNNING with External Error Detected: this exception condition is indicated by the MS Status
LED, which displays solid green with 1 red flash. You may exit this state by clearing the external detected error. No controller commands are required.
RUNNING with Breakpoint: this exception condition is indicated by the MS Status LED, which displays 3 green flashes. Refer to Controller States Description
( see page 53 ) for further details.

Note 11
When Starting Mode is set to Start in run and if the Run/Stop input is not configured, the controller will reboot in STOPPED state. A second reboot will be necessary to set the controller in RUNNING state.
Note 12
Remanent variables can be invalid if battery is not present for example.
Note 13
The boot application can be different from the application loaded. It can happen when the boot application was downloaded through USB Key, FTP or File Transfer or when an online change was performed without creating the boot application.

Description
The controller executes the boot firmware and its own internal self-tests. It then verifies the checksum of the firmware and user applications. It does not execute the application nor does it communicate.
This state is the same as the normal BOOTING state except that a flag is set to make it appear as if no Boot application is present and the LED indications are different.
There is not a valid firmware file present In the Flash memory. The controller does not execute the application.
Communication is only possible through the USB host port, and then only for uploading a valid OS.
Refer to Upgrading Modicon M258 Motion Controller
.
There is no application present or an invalid application. PCI expansion modules are inactive.
This state is the same as the normal EMPTY state except that a flag is set to make it appear as if no Boot Application is present (no Application is loaded) and the LED indications are different.
The controller is executing a valid application.
This state is the same as the RUNNING state with the following exceptions:
The task-processing portion of the program does not
resume until the breakpoint is cleared.
The LED indications are different.

CAN bus behaves as if the Update IO while in stop option was not selected when managed by a task responsible for the Application Detected Error. Else, CAN bus behavior follows the actual setting.
The LED indications are different.
Single red flash
Details of the STOPPED State
The following statements are true for the STOPPED state:
The input configured as the Run/Stop input remains operational.
The output configured as the Alarm output remains operational and goes to a value of 0.
Ethernet, Serial (Modbus, ASCII, etc.), and USB communication services remain operational and commands written by these services can continue to affect the application, the controller state, and the memory variables.
Outputs initially assume their configured default state (Keep current values or Set all outputs to default) or the state dictated by output forcing if used. The subsequent state of the outputs depends on the value of the Update IO while in stop setting and on commands received from remote devices.
Task and I/O Behavior When Update IO While In Stop Is Selected
When the Update IO while in stop setting is selected:
The Read Inputs operation continues normally. The physical inputs are read and then written to the %I input memory variables.
The Task Processing operation is not executed.
The Write Outputs operation continues. The %Q output memory variables are updated to reflect either the Keep current values configuration or the Set all outputs to default configuration, adjusted for any output forcing, and then written to the physical outputs.
NOTE: Expert functions continue to operate. For example, a counter will continue to count.
However, these Expert functions do not affect the state of the outputs. The outputs of Expert
I/O conform to the behavior stated here.
NOTE: Commands received by Ethernet, Serial, USB and CAN communications can continue to write the memory variables. Changes to the %Q output memory variables are written to the physical outputs.
EIO0000004135 09/2020
55
Controller States and Behaviors
CANopen Behavior When Update IO While In Stop Is Selected
The following is true for the CANopen buses when the Update IO while in stop setting is selected:
The CANopen bus remains fully operational. Devices on the CANopen bus continue to
perceive the presence of a functional CANopen Master.
TPDO and RPDO continue to be exchanged.
The optional SDO, if configured, continue to be exchanged.
The Heartbeat and Node Guarding functions, if configured, continue to operate.
If the Behaviour for outputs in Stop field is set to Keep current values, the TPDOs continue to be issued with the last actual values.
If the Behaviour for outputs in Stop field is Set all outputs to default the last actual values are updated to the default values and subsequent TPDOs are issued with these default values.
Task and I/O Behavior When Update IO While In Stop Is Not Selected
When the Update IO while in stop setting is not selected, the controller sets the I/O to either the
Keep current values or Set all outputs to default condition (as adjusted for output forcing if used).
After this, the following becomes true:
The Read Inputs operation ceases. The %I input memory variables are frozen at their last
values.
The Task Processing operation is not executed.
The Write Outputs operation ceases. The %Q output memory variables can be updated via the Ethernet, Serial, and USB connections. However, the physical outputs are unaffected and retain the state specified by the configuration options.
NOTE: Expert functions cease operating. For example, a counter will be stopped.
CANopen Behavior When Update IO While In Stop Is Not Selected
The following is true for the CANopen buses when the Update IO while in stop setting is not selected:
The CANopen Master ceases communications. Devices on the CANopen bus assume their
configured fallback states.
TPDO and RPDO exchanges cease.
Optional SDO, if configured, exchanges cease.
The Heartbeat and Node Guarding functions, if configured, stop.
The current or default values, as appropriate, are written to the TPDOs and sent once before stopping the CANopen Master.

Controller States and Behaviors
Controller States and Output Behavior
Introduction
The Modicon M258 Logic Controller defines output behavior in response to commands and system events in a way that allows for greater flexibility. An understanding of this behavior is necessary before discussing the commands and events that affect controller states. For example, typical controllers define only two options for output behavior in stop: fallback to default value or keep current value.
The possible output behaviors and the controller states to which they apply are:
Managed by Application Program
Keep current values
Set all outputs to default
Hardware Initialization Values
Software Initialization Values
Output Forcing
Managed by Application Program
Your application program manages outputs normally. This applies in the RUNNING and RUNNING with External Error Detected states.
Keep Current Values
Select this option by choosing Controller Editor → PLC settings → Behavior for outputs in Stop →
Keep current values. To access the Controller Editor, right-click on the controller in the device tree and select Edit Object.
This output behavior applies in the STOPPED controller state. It also applies to CAN bus in the
HALT controller state. Outputs are set to and maintained in their current state, although the details of the output behavior vary greatly depending on the setting of the Update I/O while in stop option and the actions commanded via configured fieldbusses. Refer to Controller States Description
( see page 53 ) for more details on these variations.
Set All Outputs to Default
Select this option by choosing Controller Editor → PLC settings → Behavior for outputs in Stop →
Set all outputs to default. To access the Controller Editor, right-click on the controller in the device tree and select Edit Object.
This output behavior applies:
when the controller is going from RUN state to STOPPED state.
if the controller is going from RUN state to HALT state.
after application download.
after reset warm/cold command.
after a reboot.
58
EIO0000004135 09/2020
Controller States and Behaviors
It also applies to CAN bus in the HALT controller state. Outputs are set to and maintained in their current state, although the details of the output behavior vary greatly depending on the setting of the Update I/O while in stop option and the actions commanded via configured fieldbusses.Refer
to Controller States Description ( see page 53 )
for more details on these variations.
Hardware Initialization Values
This output state applies in the BOOTING, EMPTY (following power cycle with no boot application or after the detection of a system error), and INVALID_OS states. It also applies to Expert I/O and
TM5 I/O busses in the HALT controller state.
In the initialization state, analog, transistor, and relay outputs assume the following values:
For an analog output: Z (high impedance)
For a fast transistor output: Z (high impedance)
For a regular transistor output: 0 Vdc
For a relay output: Open
Software Initialization Values
This output state applies when downloading or when resetting the application. It applies at the end of the download or at the end of a reset warm or cold.
The software Initialization Values are the initialization values of outputs images (%I, %Q, or variables mapped on %I or %Q).
By default, they are set to 0 but it is possible to map the I/O in a GVL and assign to the outputs a value different than 0.
Output Forcing
The controller allows you to force the state of selected outputs to a defined value for the purposes of system testing, commissioning, and maintenance.
You are only able to force the value of an output while your controller is connected to EcoStruxure
Machine Expert.
To do so, use the Force values command in the Debug menu.
Output forcing overrides all other commands (except write immediate) to an output irrespective of the task programming that is being executed.
When you logout of EcoStruxure Machine Expert when output forcing has been defined, you are presented with the option to retain output forcing settings. If you select this option, the output forcing continues to control the state of the selected outputs until you download an application or use one of the Reset commands.
When the option Update I/O while in stop, if supported by your controller, is checked (default state), the forced outputs keep the forcing value even when the logic controller is in STOP.
EIO0000004135 09/2020
59
Controller States and Behaviors
Output Forcing Considerations
The output you wish to force must be contained in a task that is currently being executed by the controller. Forcing outputs in unexecuted tasks, or in tasks whose execution is delayed either by priorities or events has no effect on the output. However, once the task that had been delayed is executed, the forcing takes effect at that time.
Depending on task execution, the forcing could impact your application in ways that may not be obvious to you. For example, an event task could turn on an output. Later, you may attempt to turn off that output but the event is not being triggered at the time. This would have the effect of the forcing being apparently ignored. Further, at a later time, the event could trigger the task at which point the forcing would take effect.
WARNING
UNINTENDED EQUIPMENT OPERATION
You must have a thorough understanding of how forcing will affect the outputs relative to the tasks being executed.
Do not attempt to force I/O that is contained in tasks that you are not certain will be executed in a timely manner, unless your intent is for the forcing to take affect at the next execution of the task whenever that may be.
If you force an output and there is no apparent affect on the physical output, do not exit
EcoStruxure Machine Expert without removing the forcing.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Commanding State Transitions
Run Command
Effect: Commands a transition to the RUNNING controller state.
Starting Conditions: BOOTING or STOPPED state.
Methods for Issuing a Run Command:
Run/Stop Input: If configured, command a rising edge to the Run/Stop input (assuming the
Run/Stop switch is in the RUN position). Set the Run/Stop to 1 for all of the subsequent options to be effective.
Refer to Run/Stop Input ( see page 85 )
for more information.
EcoStruxure Machine Expert Online Menu: Select the Start command.
RUN command from Web Server
By an external call via Modbus request using the PLC_W.q_wPLCControl and
PLC_W.q_uiOpenPLCControl system variables of the M258 PLCSystem library.

Controller States and Behaviors
The file system employed by the controller needs to be periodically re-established by a power cycle of the controller. If you do not perform regular maintenance of your machine, or if you are using an Uninterruptible Power Supply (UPS), you must force a power cycle (removal and reapplication of power) to the controller at least once a year.
NOTICE
DEGRADATION OF PERFORMANCE
Reboot your controller at least once a year by removing and then reapplying power.
Failure to follow these instructions can result in equipment damage.
For details on variables, refer to Remanent Variables ( see page 69 )
.
NOTE: The Check context test concludes that the context is valid when the application and the remanent variables are the same as defined in the Boot application.
NOTE: If you provide power to the Run/Stop input from the same source as the controller, the loss of power to this input is detected immediately, and the controller behaves as if a STOP command was received. Therefore, if you provide power to the controller and the Run/Stop input from the same source, your controller reboots normally into the STOPPED state after a power interruption when Starting Mode is set to Start as previous state.
NOTE: If you make an online change to your application program while your controller is in the
RUNNING or STOPPED state but do not manually update your Boot application, the controller detects a difference in context at the next reboot, the remanent variables are reset as per a Reset cold command, and the controller enters the STOPPED state.
Download Application
Effect: Loads your application executable into the RAM memory. Optionally, creates a Boot application in the Flash memory.
Starting Conditions: RUNNING, STOPPED, HALT, and EMPTY states.
Methods for Issuing the Download Application Command:

Error Detection, Types, and Management
Error Management
The controller detects and manages three types of errors:
External errors
Application errors
System errors
This table describes the types of errors that may be detected:
Type of Error
Detected
External Error
Description
External errors are detected by the system while RUNNING or
STOPPED but do not affect the ongoing controller state. An external error is detected in the following cases:
A connected device reports an error to the controller.
The controller detects an error with an external device, for example, when the external device is communicating but not properly configured for use with the controller.
The controller detects an error with an output.
The controller detects a communication interruption with a device.
The controller is configured for a module that is not present or not detected.
The boot application in Flash memory is not the same as the one in RAM.
Application Error An application error is detected when improper programming is encountered or when a task watchdog threshold is exceeded.
Resulting Controller

System Error A system error is detected when the controller enters a condition that cannot be managed during runtime. Most such conditions result from firmware or hardware exceptions, but there are some cases when incorrect programming can result in the detection of a system error, for example, when attempting to write to memory that was reserved during runtime, or when a system watchdog time-out occurs.
NOTE: There are some system errors that can be managed by runtime and are therefore treated like application errors.

Controller States and Behaviors
Remanent Variables
Overview
Remanent variables can either be reinitialized or retain their values in the event of power outages, reboots, resets, and application program downloads. There are multiple types of remanent variables, declared individually as retain or persistent, or in combination as retain-persistent.
NOTE: For this controller, variables declared as persistent behave in the same way as variables declared as retain-persistent.
This table describes the behavior of remanent variables in each case:

(1) Retain variable values are maintained if an online change modifies only the code part of the boot application (for example, a:=a+1; => a:=a+2; ). In all other cases, retain variables are reinitialized.
(2) For more details on VAR RETAIN, refer to Effects of the Reset warm Command
.
(3) If the application is downloaded using a USB memory key, any existing retain-persistent variables used by the application are reinitialized. If the application is downloaded using EcoStruxure Machine Expert, however, existing retain-persistent variables maintain their values. In both cases, if the downloaded application contains the same retain-persistent variables as the existing application, the existing retain variables maintain their values.
NOTE: The first 1000 %MW are automatically retained and persistent if no variable is associated to them. Their values are kept after a reboot / Reset warm / Reset cold. The other %MW are managed as VAR.
For example, if you have in your program:
VAR myVariable AT %MW0 : WORD; END_VAR
%MW0 behaves like myVariable (not retained and not persistent).

In the Applications tree, select the Application node.
Click the right mouse button.

Result: The PersistentVars window is displayed.
Retain and Persistent Variables: Performance Impact
Retain or retain-persistent variables are located in a dedicated non-volatile memory. Each time these variables are accessed during Programming Organization Unit (POU) execution, the nonvolatile memory is accessed. The access time of these variables is slower than the access time of regular variables, which can impact performance. This is an important fact to take into account when writing performance-sensitive POUs.

Troubleshooting
The only way to gain access to a controller that has user access-rights enabled and for which you do not have the password(s) is by performing an Update Firmware operation. This clearing of User
Rights can only be accomplished by using an SD card or a USB key (depending on the support of your particular controller) to update the controller firmware. In addition, you may clear the User
Rights in the controller by running a script (for more information, refer to EcoStruxure Machine
Expert Programming Guide). This effectively removes the existing application from the controller memory, but restores the ability to access the Controller.

From the STOPPED state, initiates a start-up of an application in RUNNING state.
The application can be controlled by:
EcoStruxure Machine Expert (Run/Stop)
the application (Controller command) a network command
NOTE: Run/Stop input is managed even if the option Update IO while in stop is not selected in the
PLC settings tab
Inputs assigned to configured expert functions can not be configured as Run/Stop.
WARNING
UNINTENDED MACHINE OR PROCESS START-UP
Verify the state of security of your machine or process environment before applying power to the Run/Stop input.
Use the Run/Stop input to help prevent the unintentional start-up from a remote location.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Alarm Output
This output is set logical 1 when the controller is in the RUNNING state and the application program is not stopped at a breakpoint.
Outputs assigned to configured expert functions can not be configured as the Alarm output.
NOTE:
The alarm output is set to 0 when:
a task is stopped at a breakpoint, the alarm output signals that the controller has stopped executing the application. an error is detected on the expert I/O (power interruption, short-circuit detection).

Embedded Expert I/O
Rearming Output Mode
Fast outputs of DM72F• modules are push/pull technology. In the case of an error detected (shortcircuit or over temperature), the output is put in tri-state and the condition is signaled by status bit
(DM72F• channel IB1.0) and PLC_R.i_wLocalIOStatus (refer to the Modicon M258 Logic Controller
System Functions and Variables PLCSystem Library Guide).
Two behaviors are possible:
Automatic rearming: as soon as the detected error is corrected, the output is set again according
to the current value assigned to it and the diagnostic value is reset.
Manual rearming: when an error is detected, the status is memorized and the output is forced to tri-state until user manually clears the status (see I/O mapping channel).
In the case of a short-circuit or current overload, the common group of outputs automatically enters into thermal protection mode (all outputs in the group are set to 0), and are then periodically rearmed (each second) to test the connection state. However, you must be aware of the effect of this rearming on the machine or process being controlled.
WARNING
UNINTENDED MACHINE START-UP
Inhibit the automatic rearming of outputs if this feature is an undesirable behavior for your machine or process.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Description
Filtering value reduces the effect of noise on a controller input.
Minimizes jitter on outputs by delaying the write to the physical outputs until the read inputs operation of the next
Bus cycle task starts.
(The end time of a task is often less easy to predict than the start time.)
Constraint
Enabled if input is not used by expert function.
–
NOTE: When inputs are used as regular, they can be filtered by integrator filter (refer to the
Modicon M258 Logic Controller - Hardware Guide).
When inputs are used by an expert function (Event_Latch, HSC, PWM, and so on), the corresponding lines are disabled and the filter value is over-ridden by the particular expert function.
When an output is used by an expert function, the configuration made at the DM72Fx level is ignored. Output management depends on the expert function configuration.

At the beginning of each task, the used %I memory variables for the inputs are updated from physical information.
At the end of each task, the used %Q memory variables values for the outputs are updated.
If Synchronized is disabled, the physical output is updated from the %Q memory variable value at the end of the task configured as the Bus cycle task.
If Synchronized is enabled, the physical output is updated from the %Q memory variable value at the beginning of the subsequent Bus cycle task.
NOTE: The interest is to synchronize the effective activation of output with command or motion control on network.

Introduction
Each DM72F• expert module can support expert functions. Expert functions are defined as either simple or complex. Only one type can be configured per module:
simple functions:
High Speed Counter Simple
Event_Latch I/O
complex functions:
High Speed Counter Main
Encoder
Frequency Generator (FreqGen)
Pulse Width Modulation (PWM)
When an I/O is not used by an expert function, it can be used as a regular I/O.
NOTE:
When a regular input is used as Run/Stop, it can not be used by an expert function.
When a regular output is used as Alarm, it can not be used by an expert function.

Event_Latch input function parameters are:
Parameter
Mode
Value Description
Latch (default) Latching allows incoming pulses with duration shorter than the controller scan time to be captured and recorded.
When input reaches state 1, this state is maintained until the MAST task reads the input.
Event Event detection allows to start an event task on edge.
The “External task” can be triggered by the rising edge, the falling edge, or both of the input (I0 to I3).
Constraint
Use latch inputs in MAST task only.
Maximum lead time between the input transition and the External task to start is 0.5 ms (except if a task with a greater priority is running).

TM5 Modules
Bus Cycle Time
Bus Cycle Time can be configured from 0.5 to 5 ms. Very fast cycles reduce the idle time for handling monitoring, diagnostics and acyclic commands.
The Bus Cycle Time follows 2 rules:
Be longer than the greatest Minimum Cycle Time of any expansion module or block in the
configuration.
Be long enough to permit the data exchange with all the modules and the blocks.
Minimum Cycle Time
The Minimum Cycle Time of a module or of a block is the time needed by the module or the block to perform I/O management. If the Bus Cycle Time is shorter than this minimum value, the module will not operate properly.
Minimum I/O Update Time
The Minimum I/O Update Time of a module or block is the time needed by the module or block to update I/O on the bus. If the Bus Cycle Time is shorter than this minimum value, the I/O will be updated on the bus at the next Bus Cycle Time.
I/O Management
At the beginning of each task, the %I memory variable for the inputs used in the task is updated with the physical state of the input.
At the end of each task, the used %Q memory variable value for the outputs is updated.
On the next bus cycle after the end of the task configured as the Bus cycle task, the physical output is updated from the %Q memory variable value.
For more details on Bus cycle task, refer to the controller PLC settings tab.

NOTE: The current consumption figures presented by the Power consumption function are based on assumed values, and not on actual current measurements. The assumed values for the outputs are based on classic loads but can be adjusted using the 24 Vdc I/O segment external current setting in the I/O Configuration tab of each module (refer to the Modicon TM5 Expansion Modules
Configuration Programming Guide). The assumptions for input signals are based on known internal loads and are therefore not modifiable. While the use of the Power consumption function to test the power budget is required, it is no substitute for actual and complete system testing and commissioning.

AI4LE Embedded Regular I/O Module
Introduction
The AI4LE embedded regular I/O module is a ±10 Vdc/0...20 mA/4...20 mA analog input module with 4 inputs.
If you have wired your input for a voltage measurement, and you configure EcoStruxure Machine
Expert for a current type of measurement (or vice-versa), you may permanently damage the electronic module.
NOTICE
INOPERABLE EQUIPMENT
Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel.
Failure to follow these instructions can result in equipment damage.

Analog Inputs
The input status is registered with a fixed offset with respect to the network cycle and is transferred in the same cycle.
Input Filter
The electronic module is equipped with a configurable Input filter. Filtering is automatically deactivated for shorter cycle times (t < 500 µs).
If the Input filter is active, then all of the input channels are repeatedly scanned with millisecondlevel resolution. The time offset between the channels is 200 µs. The conversion of the physical signal at the input to the filtered signal takes place asynchronously to the Bus Cycle Time. Refer to Cycle time and I/O update time tab (Modicon TM5 Expansion Modules Configuration
Programming Guide) .

0 mA = 0
20 mA = +32767
0 mA = -8192
4 mA = 0
20 mA = +32767
If the Lower limit value is configured between -32768 and
+32767, the digital value is limited to the Lower limit value.
If the Lower limit value is configured between -32768 and 0, the digital value is limited to 0.
If the Lower limit value is configured between 0 and 32 767, the digital value is limited to the Lower limit value.
If the Lower limit is configured between -32768 and -8192, the digital value is limited to -8192.
If the Lower limit is configured between -8192 and 32767, the digital value is limited to the Lower limit value.
The Upper limit value range is between -32768 to 32767. This value is applied on every channel of the module being configured.
NOTE: The Upper limit value cannot be less than the Lower limit value.

Input Ramp Limitation
Input ramp limitation can only take place when a filter is used. Input ramp limitation is executed before filtering takes place.
The amount of the change in the input value is checked to ensure the specified limits are not exceeded. If the values are exceeded, the adjusted input value is equal to the old value ± the limit value.
This table shows the adjustable limit values:
Limit Value
The input value is used without limitation.
3FFF hex = 16383

0FFF hex = 4095
07FF hex = 2047
03FF hex = 1023
01FF hex = 511

TM5 Digital I/O modules
TM5 Analog I/O modules
TM5 Temperature Analog modules
TM5 Analog Strain modules
TM5 Expert modules
TM5 Transmitter - Receiver modules
TM5 Power distribution modules
TM5 Common distribution modules
TM5 Dummy modules
Compact, digital, and analog input modules convert measured values (voltages, currents) into numerical values that can be processed by the controller.
Compact, digital, and analog output modules convert controller-internal numerical values into voltages or currents.
Expert modules are used for counting. They use either a Synchronous Serial Interface (SSI) encoder, incremental encoder, or event counting.
The transmitter and receiver modules handle the communication between remote modules via expansion bus cables.
Power distribution modules are used to manage the power supply for the various I/O modules.
Common distribution modules provide 0 Vdc and/or 24 Vdc terminal connections for the 24 Vdc I/O power segment(s) integrated into the bus bases, which expand the wiring possibilities for sensors and actuators.
The dummy module is a non-functional module. This module is used to separate modules which have specific thermal or EMC requirements, or as a placeholder for later system expansion.

Match Software and Hardware Configuration
The I/O that may be embedded in your controller is independent of the I/O that you may have added in the form of I/O expansion. It is important that the logical I/O configuration within your program matches the physical I/O configuration of your installation. If you add or remove any physical I/O to or from the I/O expansion bus or, depending on the controller reference, to or from the controller (in the form of cartridges), then you must update your application configuration. This is also true for any field bus devices you may have in your installation. Otherwise, there is the potential that the expansion bus or field bus no longer function while the embedded I/O that may be present in your controller continues to operate.
WARNING
UNINTENDED EQUIPMENT OPERATION
Update the configuration of your program each time you add or delete any type of I/O expansions on your I/O bus, or you add or delete any devices on your field bus.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
To verify if the hardware and the software configuration match, use the GVL TM5_Module_R regularly to monitor the expansion bus status.

TM7 Expansion Modules General Description
Introduction
TM5 EtherNet/IP Fieldbus Interface is compatible with TM7 Expansion modules via the TM5 data transmitter electronic module (TM5SBET7).
The range of expansion I/O includes:
TM7 Digital I/O blocks
TM7 Analog I/O blocks
TM7 Power distribution blocks
Digital or analog input blocks convert measured values (voltages, currents) into numerical values which can be processed by the controller.
Digital or analog output blocks convert controller internal numerical values into voltages or currents.
Analog temperature blocks convert the temperature measurement values into number values which can be processed by the controller. For temperature measurements, the temperature block returns the measured value using 0.1 °C (0.18 °F) steps.
The Power Distribution Blocks PDB are used to manage the power supply for the various I/O blocks. The PDB feeds the TM7 power bus.
NOTE: The TM7 I/O blocks are associated with power cables, TM7 bus cables and I/O cables.

Ethernet Configuration
Each connection based on TCP manages its own set of connections as follows:
1. When a client tries to open a connection that exceeds the poll size, the controller closes the oldest connection.
2. If all connections are busy (exchange in progress) when a client tries to open a new one, the new connection is denied.
3. All server connections stay open as long as the controller stays in operational states ( RUNNING ,
STOPPED , HALT ).
4. All server connections are closed when leaving or entering operational states ( RUNNING ,
STOPPED , HALT ), except in case of power outage (because the controller does not have time to close the connections).
Services Available
With an Ethernet communication, the IEC VAR ACCESS service is supported by the controller.
With the IEC VAR ACCESS service, data can be exchanged between the controller and an HMI.
The NetWork variables service is also supported by the controller. With the NetWork variables service, data can be exchanged between controllers.

There are different ways to assign the IP address to the added Ethernet interface of the controller:
Address assignment by DHCP server
Address assignment by BOOTP server
Fixed IP address
Post configuration file
has priority over the others.
. If a post configuration file exists, this assignment method
The IP address can also be changed dynamically through the:
Controller Selection tab in EcoStruxure Machine Expert
changeIPAddress function block
NOTE: If the attempted addressing method is unsuccessful, the link uses a default IP address
derived from the MAC address.
Carefully manage the IP addresses because each device on the network requires a unique address. Having multiple devices with the same IP address can cause unintended operation of your network and associated equipment.
WARNING
UNINTENDED EQUIPMENT OPERATION
Verify that there is only one master controller configured on the network or remote link.
Verify that all devices have unique addresses.
Obtain your IP address from your system administrator.
Confirm that the IP address of the device is unique before placing the system into service.
Do not assign the same IP address to any other equipment on the network.
Update the IP address after cloning any application that includes Ethernet communications to a unique address.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: Verify that your system administrator maintains a record of assigned IP addresses on the network and subnetwork, and inform the system administrator of any configuration changes performed.

NOTE: If a device programmed to use the DHCP or BOOTP addressing methods is unable to contact its respective server, the controller uses the default IP address. It repeats its request constantly.
The IP process restarts in the following cases:
Controller reboot
Ethernet cable reconnection
Application download (if IP parameters change)
DHCP or BOOTP server detected after a prior addressing attempt was unsuccessful.

Description
Name for the network link.
Used as device name to retrieve IP address through
DHCP, maximum 15 characters.
IP address is obtained by DHCP server.
IP address is obtained by BOOTP server.
IP address, Subnet Mask, and Gateway Address are defined by the user.
Protocol type used (Ethernet 2 or IEEE 802.3)
NOTE: If you change the Ethernet Protocol, a power cycle is required before it will be recognized by the controller.
Speed and Duplex are in auto-negotiation mode.
Default IP Address
The IP address by default is 10.10.x.x.
The last two fields in the default IP address are composed of the decimal equivalent of the last two hexadecimal bytes of the MAC address of the port.
The MAC address of the port can be retrieved on the label placed on the front side of the controller.
The default subnet mask is Default Class A Subnet Mask of 255.0.0.0.
NOTE: A MAC address is written in hexadecimal format and an IP address in decimal format.
Convert the MAC address to decimal format.
Example: If the MAC address is 00.80.F4.01.80.F2, the default IP address is 10.10.128.242.
Address Classes
The IP address is linked:
to a device (the host)
to the network to which the device is connected
An IP address is always coded using 4 bytes.
The distribution of these bytes between the network address and the device address may vary.This distribution is defined by the address classes.

Subnet Mask
The subnet mask is used to address several physical networks with a single network address. The mask is used to separate the subnetwork and the device address in the host ID.
The subnet address is obtained by retaining the bits of the IP address that correspond to the positions of the mask containing 1, and replacing the others with 0.
Conversely, the subnet address of the host device is obtained by retaining the bits of the IP address that correspond to the positions of the mask containing 0, and replacing the others with 1.
Example of a subnet address:
IP address
Subnet mask
192 (11000000)
255 (11111111)
Subnet address 192 (11000000)

16 (00010000)
11 (00001011)
0 (00000000)
0 (00000000)
NOTE: The device does not communicate on its subnetwork when there is no gateway.
Gateway Address
The gateway allows a message to be routed to a device that is not on the current network.
If there is no gateway, the gateway address is 0.0.0.0.
The gateway address must be defined on Ethernet_1 interface. The traffic to unknown networks is sent through this interface.

Modbus TCP Client/Server
Introduction
Unlike Modbus serial link, Modbus TCP is not based on a hierarchical structure, but on a client/server model.
The Modicon M258 Logic Controller implements both client and server services so that it can initiate communications to other controllers and I/O devices, and to respond to requests from other controllers, SCADA, HMIs, and other devices. By default, Modbus Server functionality is not active.
Without any configuration, the embedded Ethernet port of the controller supports Modbus server.
The Modbus client/server is included in the firmware and does not require any programming action from the user. Due to this feature, it is accessible in RUNNING, STOPPED and EMPTY states.
Modbus TCP Client
The Modbus TCP client supports the following function blocks from the PLCCommunication library without any configuration:
ADDM
READ_VAR
SEND_RECV_MSG
SINGLE_WRITE
WRITE_READ_VAR
WRITE_VAR
For further information, refer to the Function Block Descriptions. See EcoStruxure Machine Expert

Web Server
Introduction
As standard equipment, the controller provides an embedded Web server with a predefined, builtin website. You can use the pages of the website for module setup and control as well as application diagnostics and monitoring. These pages are ready to use with a Web browser. No configuration or programming is required.
The Web server can be accessed by the web browsers listed below:
Google Chrome (version 65.0 or greater)
Mozilla Firefox (version 54 or greater)
Microsoft Internet Explorer (version 11 or greater)
The Web server is limited to 10 TCP connections
.
The Web server has full access to your application for reading and writing data and controlling the state of the controller. By enabling the Web server, you enable these functions. You can disable the Web server on an interface by deselecting the Web Server active parameter in the Ethernet
Configuration tab ( see page 143 ) .
The Web server is a tool for reading and writing data, and controlling the state of the controller, with full access to all data in your application. However, if there are security concerns over these functions, you must at a minimum assign a secure password to the Web Server or disable the Web server to help prevent unauthorized access to the application. By enabling the Web server, you enable these functions.
EIO0000004135 09/2020
149
Ethernet Configuration
The Web server allows you to monitor a controller and its application remotely, to perform various maintenance activities including modifications to data and configuration parameters, and change the state of the controller. Care must be taken to ensure that the immediate physical environment of the machine and process is in a state that will not present safety risks to people or property before exercising control remotely.
WARNING
UNINTENDED EQUIPMENT OPERATION
Configure and install the RUN/STOP input for the application, if available for your particular controller, so that local control over the starting or stopping of the controller can be maintained regardless of the remote commands sent to the controller.
Define a secure password for the Web Server and do not allow unauthorized or otherwise unqualified personnel to use this feature.
Ensure that there is a local, competent, and qualified observer present when operating on the controller from a remote location.
You must have a complete understanding of the application and the machine/process it is controlling before attempting to adjust data, stopping an application that is operating, or starting the controller remotely.
Take the precautions necessary to assure that you are operating on the intended controller by having clear, identifying documentation within the controller application and its remote connection.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: The Web server must only be used by authorized and qualified personnel. A qualified person is one who has the skills and knowledge related to the construction and operation of the machine and the process controlled by the application and its installation, and has received safety training to recognize and avoid the hazards involved. No responsibility is assumed by Schneider
Electric for any consequences arising out of the use of this feature.

Web Server Access
Access to the Web server is controlled by User Rights when they are enabled in the controller. For more information, refer to Users and Groups Tab Description
To access the Web server you must first connect to the controller with EcoStruxure Machine Expert or Controller Assistant and modify the default user password.
WARNING
UNAUTHORIZED DATA ACCESS
Secure access to the FTP/Web server using User Rights.
If you disable User Rights, disable the FTP/Web server to help prevent any unwanted or unauthorized access to data in your application.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
In order to change the password, go to Users and Groups tab of the device editor. For more information, refer to the EcoStruxure Machine Expert Programming Guide (see SoMachine,
Programming Guide) .
NOTE: The only way to gain access to a controller that has user access-rights enabled and for which you do not have the password(s) is by performing an Update Firmware operation. This clearing of User Rights can only be accomplished by using a USB key to update the controller firmware. In addition, you may clear the User Rights in the controller by running a script (for more information, refer to EcoStruxure Machine Expert Programming Guide memory, but restores the ability to access the Controller.
(see SoMachine,
Programming Guide) ) . This effectively removes the existing application from the controller

Introduction
Firewall Presentation
In general, firewalls help protect network security zone perimeters by blocking unauthorized access and permitting authorized access. A firewall is a device or set of devices configured to permit, deny, encrypt, decrypt, or proxy traffic between different security zones based upon a set of rules and other criteria.
Process control devices and high-speed manufacturing machines require fast data throughput and often cannot tolerate the latency introduced by an aggressive security strategy inside the control network. Firewalls, therefore, play a significant role in a security strategy by providing levels of protection at the perimeters of the network. Firewalls are an important part of an overall, system level strategy.
NOTE: Schneider Electric adheres to industry best practices in the development and implemen tation of control systems. This includes a "Defense-in-Depth" approach to secure an Industrial
Control System. This approach places the controllers behind one or more firewalls to restrict access to authorized personnel and protocols only.
WARNING
UNAUTHENTICATED ACCESS AND SUBSEQUENT UNAUTHORIZED MACHINE
OPERATION
Evaluate whether your environment or your machines are connected to your critical infrastructure and, if so, take appropriate steps in terms of prevention, based on Defense-in-
Depth, before connecting the automation system to any network.
Limit the number of devices connected to a network to the minimum necessary.
Isolate your industrial network from other networks inside your company.
Protect any network against unintended access by using firewalls, VPN, or other, proven security measures.
Monitor activities within your systems.
Prevent subject devices from direct access or direct link by unauthorized parties or unauthen ticated actions.
Prepare a recovery plan including backup of your system and process information.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Firewall Configuration
There are three ways to manage the controller firewall configuration:
Static configuration
Dynamic changes
Application settings
Script files are used in the static configuration and for dynamic changes.
EIO0000004135 09/2020
175
Ethernet Configuration
Static Configuration
The static configuration is loaded at the controller boot.
The controller firewall can be statically configured by managing a default script file located in the controller. The path to this file is /usr/Cfg/FirewallDefault.cmd
.
Dynamic Changes
After the controller boot, the controller firewall configuration can be changed by the use of script files.
There are two ways to load these dynamic changes using:
A physical USB memory key.
A function block
in the application.

Firewall Script Commands
Overview
This section describes how script files (default script files or dynamic script files) are written so that they can be executed during the booting of the controller or during a specific command triggered.
NOTE: The MAC layer rules are managed separately and have more priority over other packet filter rules.
Script File Syntax
The syntax of script files is described in Script Syntax Guidelines.
General Firewall Commands
The following commands are available to manage the Ethernet firewall of the M258 Logic
Controller:
Command
Firewall Enable

See Adding an EtherNet Manager
EtherNet/IP Device Configuration
To configure the EtherNet/IP device parameters, double-click Ethernet → EthernetIP in the
Devices tree.
The following dialog box is displayed:
186
The EtherNet/IP configuration parameters are defined as:
Instance:
Number referencing the input or output Assembly.
Size:
Number of channels of an input or output Assembly.
The memory size of each channel is 2 bytes that stores the value of an %IWx or %QWx object, where x is the channel number.
EIO0000004135 09/2020
Ethernet Configuration
For example, if the Size of the Output Assembly is 20, it represents that there are 20 input channels (IW0...IW19) addressing %IWy...%IW(y+20-1), where y is the first available channel for the Assembly.

3
Action
In the Devices tree, right-click the EthernetIP node and choose the Export as EDS command from the context menu.
Modify the default file name and location as required.
Click Save.
NOTE: The Major Revision and Minor Revision objects in the EDS file are used to ensure uniqueness of the EDS file. The values of these objects do not reflect the actual controller revision level.
The EDS file is generated automatically in the "/usr/Eip" directory within the controller when an application is downloaded, or at start-up when a boot application exists, according to the parameters above.
NOTE: The EDS file is generated when the control network is working correctly on the controller
(cable connected and the IP address is acquired).

Modbus TCP Slave Device
Overview
This section describes the configuration of Modbus TCP Slave Device to the controller.
The Modbus TCP Slave Device is a privileged Modbus device on the network. It serves as a gateway for an external I/O scanner configured as the Modbus master, and allows this scanner to exchange data with the controller without interfering with the operation of the Modbus server on the controller. Essentially, the Modbus TCP Slave allows two Modbus masters to coexist and exchange data.
While the Modbus TCP Slave Device uses standard Modbus commands (3 h, 6 h, and so on), these commands do not have their standard meaning. As this device is acting as a gateway for an external I/O scanner (Modbus master), the schema where %IW registers are associated with inputs (read-only) and %QW registers are associated with outputs (read-write) is reversed when considered from the perspective of the external Modbus master.
For further information about Modbus TCP, refer to the www.odva.org
website.

NOTE: The timeout applies to the IP master Address unless the address is

Sends the requests to the Modbus TCP slave device (1...247), instead of to the embedded Modbus server (255).
Size of the %IW registers in bytes (2...40 bytes)
Size of the %QW registers in bytes (2...40 bytes)
Modbus TCP Slave Device I/O Mapping Tab
The I/Os are mapped to Modbus registers from the master perspective as follows:
%IWs are mapped from register 0 to n-1 and are R/W (n = Holding register quantity, each %IW
register is 2 bytes).
%QWs are mapped from register n to n+m -1 and are read only (m = Input registers quantity, each %QW register is 2 bytes).
Once a Modbus TCP Slave Device has been configured, Modbus commands sent to its Unit ID
(Modbus address) are handled differently than the same command would be when addressed to any other Modbus device on the network. For example, when the Modbus command 3 (3 hex) is sent to a standard Modbus device, it reads and returns the value of one or more registers. When this same command is sent to the Modbus TCP by the external I/O scanner.
Slave, it facilitates a read operation
The Modbus TCP Slave Device responds to a subset of the Modbus commands, but does so in a way that differs from Modbus standards, and with the purpose of exchanging data with the external
I/O scanner. The following Modbus commands are supported by the Modbus TCP slave device:
Function Code
Dec (Hex)
3 (3)
6 (6)
16 (10)
23 (17)

Action
In the Devices tree, double-click CAN0.
Configure the baudrate (by default: 250000 bits/s):
NOTE: The Online Bus Access option allows you to block SDO, DTM, and NMT sending through the status screen.
When connecting a DTM to a device using the network, the DTM communicates in parallel with the running application. The overall performance of the system is impacted and may overload the network, and therefore have consequences for the coherency of data across devices under control.
WARNING
UNINTENDED EQUIPMENT OPERATION
Place your machine or process in a state such that DTM communications will not impact its performance.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

EIO0000004135 09/2020
Serial Line Configuration
The serial line ports of your controller are configured for the Machine Expert protocol by default when new or when you update the controller firmware. The Machine Expert protocol is incompatible with that of other protocols such as Modbus Serial Line. Connecting a new controller to, or updating the firmware of a controller connected to, an active Modbus configured serial line can cause the other devices on the serial line to stop communicating. Make sure that the controller is not connected to an active Modbus serial line network before first downloading a valid application having the concerned port or ports properly configured for the intended protocol.
NOTICE
INTERRUPTION OF SERIAL LINE COMMUNICATIONS
Be sure that your application has the serial line ports properly configured for Modbus before physically connecting the controller to an operational Modbus Serial Line network.
Failure to follow these instructions can result in equipment damage.

The following section describes the differences between the Modbus memory mapping of the controller and HMI Modbus mapping. If you do not program your application to recognize these differences in mapping, your controller and HMI will not communicate correctly. Thus it will be possible for incorrect values to be written to memory areas responsible for output operations.
WARNING
UNINTENDED EQUIPMENT OPERATION
Program your application to translate between the Modbus memory mapping used by the controller and that used by any attached HMI devices.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
When the controller and the Magelis HMI are connected via Modbus (HMI is master of Modbus requests), the data exchange uses simple word requests.
EIO0000004135 09/2020
231
Serial Line Configuration
There is an overlap on simple words of the HMI memory while using double words but not for the controller memory (see following diagram). In order to have a match between the HMI memory area and the controller memory area, the ratio between double words of HMI memory and the double words of controller memory has to be 2.
The following gives examples of memory match for the double words:
%MD2 memory area of the HMI corresponds to %MD1 memory area of the controller because
the same simple words are used by the Modbus request.
%MD20 memory area of the HMI corresponds to %MD10 memory area of the controller because the same simple words are used by the Modbus request.
The following gives examples of memory match for the bits:
%MW0:X9 memory area of the HMI corresponds to %MX1.1 memory area of the controller because the simple words are split in 2 distinct bytes in the controller memory.

Post Configuration Presentation
Introduction
Post configuration is an option that allows you to modify some parameters of the application without changing the application. Post configuration parameters are defined in a file called
Machine.cfg, which is stored in the controller.
By default, all parameters are set in the application.The parameters defined in the Post
Configuration file are used instead of the corresponding parameters defined in the application. Not all parameters have to be specified in the Post Configuration file (for example: one parameter can change the IP address without changing the Gateway Address). All parameters in the Post
Configuration file without corresponding hardware are ignored (for example, a PCI module configuration without a PCI module).
Parameters
The Post Configuration file allows you to change network parameters.
Ethernet parameters:
IP Address
Subnet Mask
Gateway Address
Transfer Rate
IP Config Mode
Device Name
Serial Line parameters, for each serial line in the application (embedded port or PCI module):
Baud rate
Parity
Data bits
Stop bit
Profibus parameters, for each Profibus in the application (PCI module):
Station address
Baud rate
NOTE: Parameter updates with a Post Configuration file that impacts parameters used by other devices via a communication port are not updated in the other devices.
For example, if the IP address used by an HMI is updated in the configuration with a Post
Configuration file, the HMI uses the previous address. You must update the address used by the
HMI independently.

Post Configuration
Post Configuration File Management
Introduction
The file Machine.cfg is located in the directory /usr/cfg .
Each parameter is specified by a variable type, variable ID, and value. The format is: id[moduleType].param[paramId].paramField=value where:
moduleType is a numerical value, for example 111.
paramId is a numerical value specifying the parameter to be modified, for example 10000.
paramField is a string value that must be used in addition to the paramId to specify serial line parameters, for example, “Bauds”.
value is the value assigned to the parameter. Its type depends on the parameter data type.
Each parameter is defined on three lines in the Post Configuration file:
The first line describes the internal 'path' for this parameter.
The second line is a comment describing the parameter in a comprehensive way.
The third line is the definition of the parameter (as described above) with its value.
Post Configuration File Generation
The Post Configuration file (Machine.cfg) is generated by EcoStruxure Machine Expert.
To generate the file, proceed as follows:
2
3
Step
1
Action
In the menu bar, choose Build → Post Configuration → Generate...
Result: An explorer window is displayed.
Select the destination folder of the Post Configuration file.
Click OK.
When you use EcoStruxure Machine Expert to create a Post Configuration file (Generate), it reads the value of each parameter assigned in your application program and then writes the values to the Machine.cfg Post Configuration file. After generating a Post Configuration file, review the file and remove any parameter assignments that you wish to remain under the control of your application. Keep only those parameter assignments that you wish changed by the Post
Configuration function that are necessary to make your application portable and then modify those values appropriately.

NOTE: The controller can be in RUNNING state during firmware download.
Performing a firmware update deletes the current application program in the device, including the
Boot Application in Flash memory.
NOTICE
LOSS OF APPLICATION DATA
Perform a backup of the application program to the hard disk of the PC before attempting a firmware update.
Restore the application program to the device after a successful firmware update.
Failure to follow these instructions can result in equipment damage.
The serial line port(s) of your controller are configured for the Machine Expert protocol by default when new or when you update the controller firmware. The Machine Expert protocol is incompatible with that of other protocols such as Modbus Serial Line. Connecting a new controller to, or updating the firmware of a controller connected to, an active Modbus configured serial line can cause the other devices on the serial line to stop communicating. Ensure that the controller is not connected to an active Modbus serial line network before first downloading a valid application having the concerned port or ports properly configured for the intended protocol.
NOTICE
INTERRUPTION OF SERIAL LINE COMMUNICATIONS
Be sure that your application has the serial line port(s) properly configured for Modbus before physically connecting the controller to an operational Modbus Serial Line network.
Failure to follow these instructions can result in equipment damage.

File Transfer with USB Memory Key
Introduction
The Modicon M258 Logic Controller allows file transfers with a USB memory key. Using this key, it is not necessary to use EcoStruxure Machine Expert or an FTP Server.
To upload or download files to the controller with a USB memory key, use one of the following methods:
The clone function (use of an empty USB memory key)
A script stored in the USB memory key
When a USB memory key is inserted into the USB Data Port of the controller, the firmware searches and executes the script contained in the USB memory key (/sys/CMD/Script.cmd).
NOTE: The controller operation is not modified during file transfer.
The Mass Storage (USB or SDCard) editor lets you generate and copy the script and all necessary files into the USB memory key.
NOTE: The Modicon M258 Logic Controller accepts only USB key formatted in FAT or FAT32.
WARNING
UNINTENDED EQUIPMENT OPERATION
You must have operational knowledge of your machine or process before connecting this device to your controller.
Ensure that guards are in place so that any potential unintended equipment operation will not cause injury to personnel or damage to equipment.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
If you remove power to the device, or there is a power outage or communication interruption during the transfer of the application, your device may become inoperative. If a communication interruption or a power outage occurs, reattempt the transfer. If there is a power outage or communication interruption during a firmware update, or if an invalid firmware is used, your device will become inoperative. In this case, use a valid firmware and reattempt the firmware update.

Clone Function
The clone function allows you to upload the application from one controller and to download it only to a same controller reference.
This function clones every parameter of the controller (for example applications, firmware, data file, post configuration). Refer to Memory Mapping
NOTE: User access rights can only be copied if the Include User Rights button has been clicked
in the Maintenance: User Management Submenu → Clone management subpage
of the Web server.
By default, cloning is allowed without using the function block FB_ControlClone. If you want to restrict access to the cloning feature, you can remove the access rights of the USBExecCommand object
on Everyone group ( see page 81 ) . As a result, cloning will be not allowed without using
FB_ControlClone. For more details about this function block, refer to the M258 PLCSystem Library
Guide. For more details about Access Rights, refer to the EcoStruxure Machine Expert
Programming Guide.
To control access to the cloned application in the target controller, use the Include users rights button (in the Clone Management subpage of the Web Server
) of the source controller before doing the clone operation. For more details about Access Rights, refer to the
EcoStruxure Machine Expert Programming Guide.

B
BCD
( binary coded decimal ) The format that represents decimal numbers between 0 and 9 with a set of
4 bits (a nybble/nibble, also titled as half byte). In this format, the 4 bits used to encode decimal numbers have an unused range of combinations.
For example, the number 2,450 is encoded as 0010 0100 0101 0000 .
BOOL
( boolean ) A basic data type in computing. A BOOL variable can have one of these values: 0
( FALSE ), 1 ( TRUE ). A bit that is extracted from a word is of type BOOL ; for example, %MW10.4
is a fifth bit of memory word number 10.
Boot application
( boot application ) The binary file that contains the application. Usually, it is stored in the controller and allows the controller to boot on the application that the user has generated.
BOOTP
( bootstrap protocol ) A UDP network protocol that can be used by a network client to automatically obtain an IP address (and possibly other data) from a server. The client identifies itself to the server using the client MAC address. The server, which maintains a pre-configured table of client device
MAC addresses and associated IP addresses, sends the client its pre-configured IP address.
BOOTP was originally used as a method that enabled diskless hosts to be remotely booted over a network. The BOOTP process assigns an infinite lease of an IP address. The BOOTP service utilizes UDP ports 67 and 68.
byte
A type that is encoded in an 8-bit format, ranging from 00 hex to FF hex.
C
CAN
( controller area network ) A protocol (ISO 11898) for serial bus networks, designed for the intercon nection of smart devices (from multiple manufacturers) in smart systems and for real-time industrial applications. Originally developed for use in automobiles, CAN is now used in a variety of industrial automation control environments.
CANopen
An open industry-standard communication protocol and device profile specification (EN 50325-4).
CFC
( continuous function chart ) A graphical programming language (an extension of the IEC 61131-3 standard) based on the function block diagram language that works like a flowchart. However, no networks are used and free positioning of graphic elements is possible, which allows feedback loops. For each block, the inputs are on the left and the outputs on the right. You can link the block outputs to the inputs of other blocks to create complex expressions.

CIP
( common industrial protocol ) When a CIP is implemented in a network application layer, it can communicate seamlessly with other CIP-based networks without regard to the protocol. For example, the implementation of CIP in the application layer of an Ethernet TCP/IP network creates an EtherNet/IP environment. Similarly, CIP in the application layer of a CAN network creates a
DeviceNet environment. In that case, devices on the EtherNet/IP network can communicate with devices on the DeviceNet network through CIP bridges or routers.
