Chapter 9 Dedicated Instructions; List Of Dedicated Instructions, Applicable Devices, And Precautions - Mitsubishi Electric MELSEC-Q Series User Manual

CHAPTER 9
Dedicated instructions facilitate programming for using intelligent function modules.
A master/local module can perform the following operations by using dedicated instructions.
• Transient transmission to a master station, local station, and intelligent device station
• Network parameter settings for a master station
• Message transmission to remote device stations

DEDICATED INSTRUCTIONS
Instruction
Reads data from the buffer memory areas of the target station or the
G(P).RIRD
device in the CPU module of the target station.
Writes data to the buffer memory areas of the target station or the
G(P).RIWT
device in the CPU module of the target station.
G(P).RIRD Reads data from the buffer memory areas of the target station.
G(P).RIWT Writes data to the buffer memory areas of the target station
Automatically performs handshaking with the target station and
reads data from the buffer memory areas of the target station.
G(P).RIRCV
The instruction is available for modules that have interlock signals
for the handshake (e.g. AJ65BT-R2(N)).
Automatically performs handshaking with the target station and
writes data to the buffer memory areas of the target station.
G(P).RISEND
The instruction is available for modules that have interlock signals
for the handshake (e.g. AJ65BT-R2(N)).
Reads data from the automatic update buffer of the target station.
G(P).RIFR The instruction is available for modules that have the automatic
update buffer (e.g. AJ65BT-R2(N)).
Writes data to the automatic update buffer of the target station.
G(P).RITO The instruction is available for modules that have the automatic
update buffer (e.g. AJ65BT-R2(N)).
Sets the network parameters to the master station and starts up the
G(P).RLPASET
data link.
Reads/writes parameters from the master station to the remote
device station and reads out the status.
G(P).RDMSG The instrunctions can be used with the remote device station, for
example NZ2AW1C2AL, that supports the message transmission
function.
