Appendix 5 Dedicated Instruction
Appendix 5 Dedicated Instruction
This section describes dedicated instructions that can be used in the Simple Motion modules.
For details on dedicated instructions, refer to the following.
MELSEC iQ-R Programming Manual (CPU Module Instructions, Standard Functions/Function Blocks)
Link dedicated instructions
The following table lists the instructions used for transient transmission to or from programmable controllers on other stations.
Each link dedicated instruction allows access to a station on a network other than CC-Link IE Field Network. (Excluding the
REMFR and REMTO instructions)
Do not write clock data to the remote head module or head module. Even when clock data is written, it will be overwritten by
the clock data of the master station clock data via the network.
■Transient transmission range of the link dedicated instruction
In a single network system, communication with all stations on the network is possible.
In multi-network system, communications can be made with stations up to eight networks apart.
CC-Link dedicated instructions
The following table lists the instructions used for transient transmission with CC-Link IE Field Network-compliant devices.
■Transient transmission range of CC-Link dedicated instructions
Communication with all stations in the same network is possible.
Communication is not available with stations in other networks.
Instruction Description
READ Reads data from the word device of another station.
SREAD Reads data from the word device of another station. (with completion device)
WRITE Writes data in the word device of another station.
SWRITE Writes data in the word device of another station. (with completion device)
SEND Sends data to another station.
RECV Reads the receive data from another station. (for main program)
RECVS Reads the receive data from another station. (for interrupt program)
REQ Requests the remote RUN/STOP to the CPU module on another station.
Reads/writes clock data from/to another station.
REMFR Reads data from the buffer memory in the intelligent device station/remote device station. (In units of words, 16-bit address
specification)
REMTO Writes data to the buffer memory in the intelligent device station/remote device station. (In units of words, 16-bit address
specification)
Instruction Description
RIRD Reads the specified points of data from the target station device.
RIWT Writes the specified points of data to the target station device.
