Appendix 5 Dedicated Instruction - Mitsubishi Electric RD77GF8 User Manual

Appendix 5
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)
Instruction
READ
SREAD
WRITE
SWRITE
SEND
RECV
RECVS
REQ
REMFR
REMTO
Precautions
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.
Instruction
RIRD
RIWT
■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.
