Twido Overview
Communications Overview
Introduction
Twido bases have one, or an optional second, serial port that is used for real-time or system management services.
Four types of communication can be used with Twido controllers: z
AS-Interface bus connection z z
CANopen fieldbus connection
Ethernet network connection z
Modem connection
The real-time services provide data distribution functions for exchanging data with
I/O devices and messaging functions for communicating to external devices.
System management services manage and configure the base through TwidoSuite.
Either serial port is used for any of these services but only serial port 1 is for communicating with TwidoSuite.
To provide these services, there are three protocols available on each base: z
Remote Link z z
Modbus
ASCII
In addition, the TWDLCAE40DRF and TWDLCDE40DRF compact bases feature a built-in RJ45 Ethernet communications port allowing to perform all real-time communications and system management tasks via the network. Ethernet communications implements the following protocol: z
Modbus TCP/IP
26 35011387 06/2011
Twido Overview
Communications Architecture with Protocols
The following diagram shows the communication architecture with all three protocols.
NOTE: Communication between the "Modbus" and "Remote Link" protocols cannot occur at the same time.
AS-Interface Connection
The AS-Interface (abbreviation for Actuator-Sensor-Interface) bus is a field bus
(level 0), and can be used to connect sensors/actuators. This allows "discrete" or analog type information to run between a bus "master" and sensor/actuator type
"slave" devices.
AS-Interface is made up of three major basic elements: z z z a specific supply providing a 30 VDC voltage, a bus master, one or more slave devices (sensors, actuators and others).
These components are interconnected by a two-wire cable dedicated to data transmission and power supply.

Twido Overview
Ethernet Network Connection
NOTE: Although direct cable connection (using a Ethernet crossover cable) is supported between the Twido TWDLCAE40DRF (or TWDLCDE40DRF) and the PC running the TwidoSuite programming software, making the connection, via a network Ethernet hub/switch, is recommended.
The following figure shows a PC-to-Twido connection via a network Ethernet hub/switch:
30
NOTE: The PC running the TwidoSuite application must be Ethernet-capable.
The Twido TWDLCAE40DRF and TWDLCDE40DRF bases feature a RJ45 connector to connect to the 100 BASE-TX network Ethernet with auto negotiation. It can accommodate both 100Mbps and 10 Mbps network speeds.
The following figure shows the RJ45 connector of the Twido controller:
The eight pins of the RJ45 connector are arranged vertically and numbered in order from bottom to top. The pinout for the RJ45 connector is described in the table below:

Modem Connection
A PC executing TwidoSuite can be connected to a Twido controller for transferring applications, animating objects and executing operator mode commands. It is also possible to connect a Twido controller to other devices, such as another Twido controller, for establishing communication with the application process.

The following information describes how the battery status can be monitored and how the battery LED management can be controlled via two system bits%S75 and%S66, respectively:
System Bit
%S75
%S66
Description
This is a read-only system bit that indicates the current battery status: z %S75 = 0: external battery is operating normally.
z %S75 = 1: external battery power is low, or battery is absent from compartment.
This system bit is writable and allows you to turn on/off the BAT LED: z Set this bit to 1 to disable the BAT LED (LED is off even if there is no z battery inside the compartment).
Set this bit to 0 to enable the BAT LED indicator. Note that the%S66 system bit is reset to 0 as default at system start-up.

RUN/STOP Input
Introduction
This section provides basic information on the RUN/STOP input special function.
Principle
The RUN/STOP input is a special function that can be assigned to anyone of the base controller inputs. This function is used to start or stop a program.
Determining the State of Run/Stop Input
At power up, if configured, the controller state is set by the Run/Stop input: z z if RUN/STOP input is at state 0, controller is in STOP mode.
if RUN/STOP input is at state 1, controller is in RUN mode.
While the controller is powered, a rising edge on the RUN/STOP input state sets the controller to RUN. The controller is stopped if the RUN/STOP input is at 0. If the
RUN/STOP input is at 0, a RUN command from a connected PC is ignored by the controller.

Controller Status Output
Introduction
This section provides basic information on the controller status output special function.
Principle
The controller status output is a special function that can be assigned to 1 of 3 outputs (%Q0.0.1 to %Q0.0.3) on a base or a remote controller.
At power up, if there is no controller error issue Base status, page 221 , the controller
status output changes to 1. This function can be used in circuits external to the controller, for example, to control: z z
The power supply to the output devices.
The controller power supply.

Latching input
Introduction
This section provides basic information on the latching inputs special function.
Principle
The latching inputs is a special function that can be assigned to one of four inputs
(%I0.0.2 to %I0.0.5) on a base or a remote controller. This function is used to memorize any pulse with a duration less than the controller scan time. When a pulse is shorter than one scan and has a value greater than or equal to 1 ms, the controller latches the pulse, which is then updated in the next scan.

Fast Counting
Introduction
This section provides basic information on the fast counting special function.
Principle
The base controllers have two fast counter types: z
A single up counter with a maximum frequency of 5 kHz.
z
A single down counter with a maximum frequency of 5 kHz.
The single up counter and single down counter functions enable up counting or down counting of pulses (rising edges) on a discrete I/O. The fast counter functions enable counting of pulses from 0 to 65535 in single-word mode and from 0 to
4294967295 in double-word mode.
Controllers Fast Counting Capabilities
Compact controllers can have up to 3 fast counters, with the exception of the
TWDLCA•40DRF series compact controllers that have 4 fast counters. Modular controllers can have up to 2 fast counters. The availability of the double-word counting option depends on the controller model. The following table lists the fast counting capabilities of the Twido line Compact and Modular controllers.

Pulse (PLS) Generator Output
Introduction
This section provides basic information on the PLS special function.
Principle
The PLS is a special function that can be assigned to output %Q0.0.0 or %Q0.0.1 on a base or a peer controller. A user-defined function block generates a signal on output %Q0.0.0 or %Q0.0.1. This signal has a variable period but has a constant duty cycle, or on to off ratio of 50% of the period.
Controllers PLS Capabilities
The number of PLS generators supported varies with the Twido controller models, as shown in the table below. Note that all controllers that have a PLS generator support both single-word and double-word functions. The following table lists the
PLS capabilities of the Twido line Compact and Modular controllers.

Introduction
This section provides basic information on the PWM special function.
Principle
The PWM is a special function that can be assigned to output %Q0.0.0 or %Q0.0.1 on a base or a peer controller. A user-defined function block generates a signal on output %Q0.0.0 or %Q0.0.1. This signal has a constant period with the possibility of varying the duty cycle, or on to off ratio.
Controllers PWM Capabilities
The number of PWM generators supported varies with the Twido controller models, as shown in the table below. Note that all controllers that have a PWM generator support both single-word and double-word functions. The following table lists the

Controller Operation
Cyclic Scan
Introduction
Cyclic scanning involves linking controller cycles together one after the other. After having effected the output update (third phase of the task cycle), the system executes a certain number of its own tasks and immediately triggers another task cycle.
NOTE: The scan time of the user program is monitored by the controller watchdog timer and must not exceed 500 ms. Otherwise an unintended operation occurs causing the controller to stop immediately in Halt mode. Outputs in this mode are forced to their default fallback state.
Operation
The following drawing shows the running phases of the cyclical scan time.

Controller Operation
Periodic Scan
Introduction
In this operating mode, acquiring inputs, processing the application program, and updating outputs are done periodically according to the time defined at configuration
(from 2-150 ms).
At the beginning of the controller scan, a timer, the value of which is initialized at the period defined at configuration, starts to count down. The controller scan must end before the timer has finished and relaunches a new scan.
Operation
The following drawing shows the running phases of the periodic scan time.

If the period has not finished, the processor completes its operating cycle until the end of the internal processing period. If the operating time is longer than that allocated to the period, the controller indicates that the period has been exceeded by setting the system bit %S19 to 1. The process continues and is run completely.
However, it must not exceed the watchdog time limit. The following scan is linked in after writing the outputs of the scan in progress implicitly.

Checking Scan Time
General
The task cycle is monitored by a watchdog timer called Tmax (a maximal duration of the task cycle). It allows the detection of application errors (infinite loops, and so on.) and specifies a maximal duration for output refreshing.
Software WatchDog (Periodic or Cyclic Operation)
In periodic or cyclic operation, the triggering of the watchdog causes a software message. The application passes into a HALT state and sets system bit%S11 to 1.
The relaunching of the task necessitates a connection to Trotskyite in order to analyze the cause of the detected error, modification of the application to correct the error, then reset the program to RUN.
NOTE: The HALT state is when the application is stopped immediately because of detection of an application software error such as a scan overrun. The data retains the current values, which allows for an analysis of the cause of the error. The program stops on the instruction in progress. Communication with the controller is open.
Check on Periodic Operation
In periodic operation an additional check is used to detect the period being exceeded: z
%S19 indicates that the period has been exceeded. It is set to: z z
1 by the system when the scan time is greater that the task period,
0 by the user.
z
%SW0 contains the period value (0-150 ms). It is: z
Initialized when starting from a cold start by the value selected on the z configuration,
Able to be modified by the user.
Using Master Task Running Time
The following system words are used for information on the controller scan cycle time: z z z z
%SW11 initializes to the maximum watchdog time (10 to 500 ms).
%SW30 contains the execution time for the last controller scan cycle.
%SW31 contains the execution time for the longest controller scan cycle since the last cold start.
%SW32 contains the execution time for the shortest controller scan cycle since the last cold start.
NOTE: This different information can also be accessed from the configuration editor.

Operating Modes
Introduction
TwidoSuite is used to take into account the three main operating mode groups: z
Checking z
Running or production z
Stopping
Starting through Grafcet
These different operating modes can be obtained either starting from or using the following Grafcet methods: z
Grafcet initialization z z z
Presetting of steps
Maintaining a situation
Freezing charts
Preliminary processing and use of system bits provide effective operating mode management without complicating and overburdening the user program.
Grafcet System Bits
Use of bits %S21, %S22 and %S23 is reserved for preliminary processing only.
These bits are automatically reset by the system. They must be written by Set
Instruction S only.
The following table provides Grafcet-related system bits:

Dealing with Power Outages and Restoration
Illustration
The following illustration shows the various power restarts detected by the system.

Controller Operation
Run/Stop Input Bit Versus Auto Run
The Run/Stop input bit has priority over the "Automatic Start in Run" option that is available from the Scan Mode dialog box. If the Run/Stop bit is set, then the controller will restart in the Run Mode when power is restored.
The mode of the controller is determined as follows:

NOTE: For all Compact type of controllers of software version V1.0, if the controller was in Run mode when power was interrupted, and the "Automatic Start in Run" flag was not set from the Scan Mode dialog box, the controller will restart in Stop mode when power is restored. Otherwise it will perform a cold restart.
NOTE: For all Modular and Compact type of controllers of software version V1.11, if the battery in the controller is operating normally when power was interrupted, the controller will startup in the mode that was in effect at the time the power was interrupted. The "Automatic Start in Run" flag, that was selected from the Scan
Mode dialog, will have no effect on the mode when the power is restored.
Operation
The table below describes the processing phases for power outages.
Phase Description
1 In the event of a power outage the system stores the application context and the time of the outage.
2 All outputs are set to fallback status (0).
3 When power is restored, the context saved is compared with the one in progress which defines the type of start to run: z If the application context has changed (loss of system context or new application), the controller initializes the application: Cold restart (systematic for z compact).
If the application context is the same, the controller restarts without initializing data: warm restart.

Resets bits %S1 and %S13 to 0 at the end of the first task cycle
Processing of a Warm-Start
In the event of a warm-start, if a particular application process is required, bit %S1 must be tested at the start of the task cycle, and the corresponding program called up.
Outputs after Power Outage
Once a power outage is detected, outputs are set to (default) fallback status (0).
When power is restored, outputs are at last state until they are updated again by the task.

Operator Display
Introduction
The Operator Display is a Twido option for displaying and controlling application data and some controller functions such as operating state and the Real-Time Clock
(RTC). This option is available as a cartridge (TWDXCPODC) for the Compact controllers or as an expansion module (TWDXCPODM) for the Modular controllers. z z
The Operator Display has two operating modes:
Display Mode: only displays data.
Edit mode: allows you to change data.
NOTE: The operator display is updated at a specific interval of the controller scan cycle. This can cause confusion in interpreting the display of dedicated outputs for
%PLS or %PWM pulses. At the time these outputs are sampled, their value will be zero, and this value will be displayed.
Displays and Functions
The Operator Display provides the following separate displays with the associated functions you can perform for each display.
z
Controller Identification and State Information: Operations Display
Display firmware revision and the controller state. Change the controller state z with the Run, Initial, and Stop commands.
System Objects and Variables: Data Display
Select application data by the address: %I, %Q, and all other software objects on the base controller. Monitor and change the value of a selected software data z z z object.
Serial Port Settings: Communication Display
Display and modify communication port settings.
Time of Day Clock: Time/Date Display
Display and configure the current date and time (if the RTC is installed).
Real Time Correction: RTC Factor
Display and modify the RTC Correction value for the optional RTC.
NOTE:
1.
The TWDLC••40DRF series of compact controllers have RTC onboard.
2.
On all other controllers, time of day clock and real-time correction are only available if the Real-Time Clock (RTC) option cartridge (TWDXCPRTC) is installed.

Controller Identification and State Information
Introduction
The initial display or screen of the Twido optional Operator Display shows the
Controller Identification and State Information.
Example
The firmware revision is displayed in the upper-right corner of the display area, and the controller state is displayed in the upper-left corner of the display area, as seen in the following:
Controller States
Controller states include any of the following: z z z z
NCF: Not Configured
The controller is in the NCF state until an application is loaded. No other state is allowed until an application program is loaded. You can test the I/O by modifying system bit S8. (see the Programming Guide for additional information about
System Bits and System Words.)
STP: Stopped
Once an application is present in the controller, the state changes to the STP or
Stopped state. In this state, the application is not running. Inputs are updated and data values are held at their last value. Outputs are not updated in this state.
INI: Initial
You can choose to change the controller to the INI or initial state only from the
STP state. The application is not running. The controller’s inputs are updated and data values are set to their initial state. No outputs are updated from this state.
RUN: Running
When in the RUN or running state the application is running. The controller’s inputs are updated and data values are set according to the application. This is the only state where the outputs are updated.
35011387 06/2011
207
Operator Display Operation z z
HLT: Halted (User Application Error Detected)
If the controller has entered an ERR or error state, the application is halted. Inputs are updated and data values are held at their last value. From this state, outputs are not updated. In this mode, the error code is displayed in the lower-right portion of the Operator Display as an unsigned decimal value.
NEX: Not Executable (not executable)
An online modification was made to user logic. Result: The application is no longer executable. It will not go back into this state until all causes for the Non-
Executable state have been resolved.
Displaying and Changing Controller States
Using the Operator Display, you can change to the INI state from the STP state, or from STP to RUN, or from RUN to STP. Do the following to change the state of the controller:

Checking I/O Connections on the Base Controller
Introduction
This section provides a procedure for checking the I/O connections.
WARNING
UNINTENDED OPERATION OF EXTERNAL EQUIPMENT z z
To avoid unintended operation of external equipment, check that:
Power fuses are removed from the motor controls.
Pneumatic and hydraulic inputs are closed.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Checking I/O Connections Procedure
The following procedure ensures that the I/O connections are connected:
Step
1
2
3
Action
To test the I/O connections, the base needs to be in the non-configured state. To accomplish this: z If an Operator Display is attached, press and hold ESC and cycle the power on the base. After the base restarts, the Operator Display indicates "NCF".
z From TwidoSuite, issue the Erase all command from the Program → Memory
Cartridge Commands task.
With the base in the non-configured state, set system bit %S8 to 0. At state 0, the base outputs are kept in their existing state.
Check the inputs by activating each external sensor. To accomplish this: z z
Check that each of the input LEDs for the corresponding bit changes state.
Using the TwidoSuite Program Debug for the corresponding bit changes state.
→ task, check that each of the input LEDs
Note: Check PLC can only be used in connected mode.
35011387 06/2011

5
Action
Check the outputs by setting the bit corresponding to each output state to 1. To accomplish this: z Check that each of the output LEDs for the corresponding bit changes state.
z Using the TwidoSuite Program → Check PLC task, check that each of the output LEDs for the corresponding bit changes state.
Note: Check PLC can only be used in connected mode.
To complete this procedure, set system bit %S8 to 1. This is automatically accomplished by downloading a valid user application.
