SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual carefully and pay full attention to safety to handle the product correctly.
In this manual, the safety precautions are classified into two levels: "
WARNING" and "
CAUTION".
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.
Under some circumstances, failure to observe the precautions given under "
CAUTION" may lead to serious
consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future reference.
[Design Precautions]
WARNING
● When connecting an external device with an SLMP compatible device to modify data of a running
programmable controller, configure an interlock circuit in the program to ensure that the entire system
will always operate safely. For other forms of control (such as program modification, parameter
change, forced output, or operating status change) of a running programmable controller, read the
relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
● Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions
to be taken between the external device and programmable controller in case of a communication
failure.
● Do not write any data to the "system area" and "write-protect area" of the buffer memory in the SLMP
compatible device or intelligent function module. Also, do not use any "use prohibited" signals as an
output signal from the CPU module to each module. Doing so may cause malfunction of the
programmable controller system. For the "system area", "write-protect area", and the "use prohibited"
signals, refer to the user's manual for the module used.
[Startup and Maintenance Precautions]
CAUTION
● Before performing online operations (especially, program modification, parameter change, forced
output, and operating status change) for the SLMP compatible device or CPU module on another
station from the peripheral device connected, read relevant manuals carefully and ensure the safety.
Improper operation may damage machines or cause accidents.

OVERVIEW
1
SLMP is a protocol used for access from an external device to an SLMP compatible device through the Ethernet. SLMP
communications are available among devices that can transfer messages by SLMP. (personal computers, human machine
interface and others.)
System monitoring from an external device
An external device connected through Ethernet can send a request message in the SLMP message format to read device
data, allowing system monitoring. Using SLMP allows not only device data reading but also device data writing and resetting
an SLMP compatible device. ( Page 24 COMMANDS)

COMMUNICATION PROCEDURE OF SLMP
An external device and a SLMP compatible device communicate in the following procedure.
3.1
When Using TCP/IP
The following is the communication procedure when executing SLMP communication with TCP/IP.
TCP/IP establishes a connection when communicating, and communicates checking that the data reached the receiver
normally, so that the reliability is ensured. However, the load of line increases comparing to UDP/IP.
External device
Connection request
Issues a connection request to the SLMP
compatible device. (Active open)
Sending a request message
Upon establishment of a connection, sends a
request message to the SLMP compatible device.
SLMP compatible device
Connection processing
Accepts the connection request from the external
device. (Passive open)
Processing
According to the message sent from the external
device, performs the requested processing such
as reading or writing.
Repeated as needed.
Receiving the response message
Receives the response message from the SLMP
compatible device, and confirms the processing
result.
Closing the connection
Issues a close request to the SLMP compatible
device, and terminates the communication on
the external device.
12
3 COMMUNICATION PROCEDURE OF SLMP
3.1 When Using TCP/IP
Returning a response message
Upon completion of the processing, sends a
response message to the external device.
Closing the connection
Accepts the close request from the external
device, and terminates the communication on
the SLMP compatible device.
3.2
When Using UDP/IP
The following is the communication procedure when executing SLMP communication with UDP/IP.
UDP/IP neither establishes a connection when communicating nor communicates checking that the data reached the receiver
normally, so that the load of line decreases. However, the reliability decreases comparing to TCP/IP.
External device
SLMP compatible device

Sending a request message
Sends a request message to the SLMP
compatible device.
Processing
According to the message sent from the external
device, performs the requested processing such
as reading or writing.
Repeated as needed.
Receiving the response message
Receives the response message from the SLMP
compatible device, and confirms the processing
result.
Returning a response message
Upon completion of the processing, sends a
response message to the external device.
End of the communication
The external device performs end processing to
terminate the communication.
3 COMMUNICATION PROCEDURE OF SLMP
3.2 When Using UDP/IP
13
3.3
Precautions
Request message transmission
Before sending a request message, the external device needs to confirm that the SLMP compatible device is ready to receive
the message.
When sending several request messages
Add a "serial No." on the subheader of each request message at the external device side, then send them. Adding a "serial
No.", the external device can identify the sender of the response message even if two or more request messages are sent.
( Page 16 Request Message)
When sending the next request message continuously
When sending the next request message with "serial No." before receiving the response message continuously, the number
of commands must not exceed the limit shown below.

If the calculation result became decimal, round it down to the nearest whole number.
The following occurs when exceeded number of commands were sent. If the following occurred, decrease frequency of
request message transmission.
• For TCP/IP, the overflow of the receive buffer of SLMP compatible device will occur. Since the window size becomes zero,
transmission of request messages will be stopped temporarily until enough receive buffer space becomes available.
• For UDP/IP, an error may occur in the SLMP compatible device, or response messages may not return from the SLMP
compatible device.
When the response message corresponding to the request message does not return
If the response message does not return from the SLMP compatible device, resend the request message from the external
device after designated time set with "monitoring timer" of the request message.
Replacing SLMP compatible device
After replacing an external device or a SLMP compatible device due to failure and so on, the devices may not communicate
by changing the MAC address. (When replaced with a device that has the same IP address)
When a device in the Ethernet network is replaced, restart all devices in the network.

Processing for a request message from the external device
1.
2.
The external device sends a request message to the SLMP compatible device.
The SLMP compatible device receives the request message from the external device. Then, the SLMP compatible
device sends a read request or a write request to the CPU module according to the message.
3.
The CPU module reads or writes the data during END processing according to the request from the external device, and
then sends back the processing result to the SLMP compatible device.
4.
Once the SLMP compatible device receives a processing result from the CPU module, it sends a response message
including the processing result to the external device.
■Read or write when the CPU module is running
• Scan time of the CPU module extends due to processing for the request from the external device. Access several times
with less points when the control is affected by the extension of the scan time.
• Before writing, check that the CPU module is allowing the write processing during the run-time. (If system protection is
unlocked, etc.)
■When the CPU module to be accessed is in system protection
An error occurs at the access destination, and an abnormal response is sent back to the external device. Unlock the system
protection of the CPU module side, and resend the request message.
■When access requests are sent to one station from several external devices at the same time
Depending on the request timing, the processing requested from the external device may be on hold until several END
processing take place. By using either of the following methods, multiple requests can be processed in one scan.
• Execute the COM instruction by program.
• Ensure 1 to 100ms of service processing time, using the "Service Processing Setting" of the engineering tool.

3.
Expand the text to be sent from the external device to 2-byte code per one character.
Sort the expanded 2-byte text by every two characters and send them to the SLMP compatible device.
Write the data sent to the SLMP compatible device to the specified device.
The following shows an example that the text ("18AF") received from the external device is converted to the binary code data
and written to D0 and D1.

Entry Monitor Device (command: 0801)
This command registers a device to be read by Execute Monitor (command: 0802). Registering the device in advance
reduces the load of line because it shortens the request message when reading.
Entry Monitor Device (command: 0801) and Execute Monitor (command: 0802) are used as follows.
1.
Monitoring device registration
By Entry Monitor Device (command: 0801), register a device to be read.
2.
Monitoring execution
Execution of Execute Monitor (command: 0802) will read values from the device registered by Entry Monitor Device
(command: 0801). ( Page 60 Execute Monitor (command: 0802))
3.
Monitoring device change
The device to be read can be changed by Entry Monitor Device (command: 0801).
• Do not execute the Entry Monitor Device command to the CPU module during the conditional monitoring.
The command of SLMP completes abnormally. The command can be executed during unconditional
monitoring.
• If the access destination is restarted, the registered data will be deleted. Execute Entry Monitor Device
again and register the device to be read.

Read Block (command: 0406)
This command reads data by treating n points of word devices or bit devices (one point is equivalent to 16 bits) as one block
and specifying multiple blocks. This can be specified with inconsecutive device No.
When the SLMP compatible device communicates with the Universal model QCPU or LCPU, the data
inconsistency may occur due to the settings other than "Specify service process execution counts" in "Service
Processing Setting" of the CPU module. To prevent the data inconsistency, set "Specify service process
execution counts".

Write Block (command: 1406)
This command writes data by treating n points of word devices or bit devices (one point is equivalent to 16 bits) as one block
and specifying multiple blocks. This can be specified with inconsecutive device No.
When the SLMP compatible device communicates with the Universal model QCPU or LCPU, the data
inconsistency may occur due to the settings other than "Specify service process execution counts" in "Service
Processing Setting" of the CPU module. To prevent the data inconsistency, set "Specify service process
execution counts".
Request data
Specify the devices for the specified number of points.

Label (Label Access)
This section describes commands which read or write data with a global label.
• Local labels cannot be accessed.
• Global labels set in GX Works2 cannot be accessed.
• To access the global label, "Access from External Device" must be enabled with the global label editor in GX
Works3. (The default setting is set to disabled.)
• When communicating data in ASCII code, the size of messages increases because the label name must be
converted from UTF-16 to ASCII code.

Label1.Member1.Member2
(only for a label to which a
device is manually assigned)
■Abbreviation definition of label name
For labels of structured type, the label name can be specified in the abbreviated form.
To use the abbreviation definition, specify the number of label names to be abbreviated, and specify and register the label
name length and label name of the label to be abbreviated.
However, the label name must be specified in a unit separated by ".". The label name cannot be specified in a character unit.
For example, for the label of structured type of "LabelA.memberA3.memberB1", "LabelA" and "LabelA.memberA3" can be
specified as the abbreviated label name. However, the label name abbreviated in a character unit, such as "Label" and
"LabelA.member", is unacceptable.
The character string of the registered label can be specified in the abbreviated form consisting of "%" and the offset value (in

The write element data differs depending on the write unit specification: bits or bytes.
For the write unit specification with bits, specify the write element data in the size rounded up in units of two bytes.
When the write unit specification does not correspond to the data type of the label, a communication error occurs and the
error code is stored in the end code of the response message. For the error codes, refer to the manual for the CPU module.
( MELSEC iQ-R CPU Module User's Manual (Application))
When the data type is the character string or an array of the character string (Unicode), specify the write element data for
every one point of the array including the value of the NULL end, and specify all the elements in the size of the number of
defined characters of the label + N.
The following table lists values of N and the NULL end.

Remote Control (Remote Operation)
This section describes the command to set the SLMP compatible device or CPU module to the RUN state or STOP state by
message from the external device.
Before the remote operation
When the accessed device or module is turned on or reset after the remote operation
The information about the remote operation will be deleted.
Ex.
Even if the remote STOP is executed when the switch of CPU module is in the RUN state, the switch will return to RUN state
after resetting the module.
When the CPU module to be accessed is in system protection
Remote operation from the external device is not available. An error occurs at the access destination, and an abnormal
response is sent back to the external device. Unlock the system protection of the CPU module side, and resend the request
message.
When executing the remote operation to SLMP compatible device
It is recommended to use UDP protocol for remote operation. If TCP is used, the connection will be terminated when resetting.
Therefore, reestablishing of connection is necessary.
Operable station in one command
Only one station can be operated remotely by one command.

Remote RUN can be executed when the switch of the access destination module is in the RUN state. Even if
the switch is in the STOP state, Remote Run (command: 1001) will be completed normally. However, the
access destination does not become the RUN state.

■Mode
This mode specifies whether the remote PAUSE can be executed forcibly by the device other than the external device which
performed the remote STOP/remote PAUSE. If the forced execution is not allowed, remote PAUSE can be executed only by
the external device which performed the remote STOP/remote PAUSE.
Forced execution is used when the external device which performed the remote operation cannot execute the remote PAUSE
because of a trouble on the device.

Precautions
The followings are precautions for file control.
Read file
When the files related to the module control, such as the program files or parameter files, are read, they are used for backup
in the external device. Do not edit the read file contents in the external device.
To back up or restore the data in the "$MELPRJ$" folder, execute the backup or restoration for all the files in the "$MELPRJ$"
folder.
When not all of the read files are restored to the "$MELPRJ$" folder, the normal operation may not be obtained.
When the protection is executed
When executing the following commands, cancel the protection of the access destination (the system protection of the CPU
module, lock of the protection switch of the SD memory card) in advance. If the command is executed while the file is
protected, an abnormal completion of the command will occur.

Precautions
• Deleting a file, while the programmable controller system is running, may stop the system. Determine the timing for deleting
a file by considering a relationship with the whole programmable controller system.
• The file locked by Open File (command: 1827) cannot be deleted. Unlock the file by Close File (command: 182A), and then
execute this command.
• When the MELSEC-Q/L series CPU module is in the RUN state, the program file, parameter file, and boot file cannot be
deleted. Set the CPU module to the STOP state, and then delete the file.
• The MELSEC iQ-R series module cannot access some file types through SLMP. For the file types that can be accessed
through SLMP, refer to the manual for the module used.
Communication example (when the subcommand is 0000)
Delete the file of the QCPU.
