Appendix 6 Dedicated Instruction - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

Appendix 6
This section describes dedicated instructions that can be used in the master/local modules.
For details on dedicated instructions, refer to the following.
 MELSEC iQ-R Programming Manual (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, REMTO, REMFRD, and REMTOD instructions)
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.
*2
REMFR Reads data from the buffer memory in the intelligent device station/remote device station. (In units of words, 16-bit address
specification)
*2
REMTO Writes data to the buffer memory in the intelligent device station/remote device station. (In units of words, 16-bit address specification)
*2
REMFRD Reads data from the buffer memory in the intelligent device station/remote device station. (In units of words, 32-bit address
specification)
*2
REMTOD Writes data to the buffer memory in the intelligent device station/remote device station. (In units of words, 32-bit address specification)
*1 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.
*2 The instruction cannot be executed on a local station. Execute it on the master station. When the submaster function is used, the
instruction can be executed only on a master operating station. Configure an interlock using 'Master/submaster function operation status
of own station' (SB004E) so that the instruction can be executed only on a master operating station. (Set SB004E to off.)
■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.
Remote instructions
The dedicated instructions used for transient transmission with the intelligent device station (remote head module).
Instruction Description
*1
SINFTYRD Reads the module model name information of the modules used for the intelligent device station.
*1
SINFSTRD Reads the status information of the modules used for the intelligent device station.
*1 When the submaster function is used, the instruction can be executed only on a master operating station. Configure an interlock using
'Master/submaster function operation status of own station' (SB004E) so that the instruction can be executed only on a master operating
station. (Set SB004E to off.)
The availability of the remote instruction depends on the firmware version of the master/local module. (

■Transient transmission range of the remote instruction
In a single network system, communication with an intelligent device station on the network is possible.
Communication is not available with stations in other networks.
