CC-Link Instructions

Reading data from the target station
Instruction symbol Processing details
G.RIRD Reads data of the specified number of points from the buffer memory area of the target station or
the device in the CPU module on the target station.
GP.RIRD
Writing data to the target station
Instruction symbol Processing details
G.RIWT Writes data of the specified number of points to the buffer memory area of the target station or the
device in the CPU module on the target station.
GP.RIWT
Reading data from the buffer memory of the specified intelligent device station
Instruction symbol Processing details
G.RIRCV Automatically performs handshake with the specified intelligent device station, and reads data from
its buffer memory.
GP.RIRCV
The instructions can be used for communications with a module supporting a handshake signal
such as AJ65BT-R2N.
Writing data to the buffer memory of the specified intelligent device station
Instruction symbol Processing details
G.RISEND Automatically performs handshake with the specified intelligent device station, and writes data to
its buffer memory.
GP.RISEND
The instructions can be used for communications with a module supporting a handshake signal
such as AJ65BT-R2N.
Reading data from the automatic update buffer
Instruction symbol Processing details
G.RIFR Reads data from an automatic update or random access buffer.
The instructions can be used for communications with a module having the automatic update buffer
GP.RIFR
such as AJ65BT-R2N.
Writing data to the automatic update buffer
Instruction symbol Processing details
G.RITO Writes data to an automatic update or random access buffer.
The instructions can be used for communications with a module having the automatic update buffer
GP.RITO
such as AJ65BT-R2N.
Setting network parameters
Instruction symbol Processing details
G.RLPASET Sets network parameters in the master station and starts up the data link.
GP.RLPASET
Performing a message transmission to a remote device station
Instruction symbol Processing details
G.RDMSG Reads/writes parameters from/to the remote device station and reads the status of the remote
device station.
GP.RDMSG
The instructions can be executed to a remote device station, for example NZ2AW1C2AL, that
supports the message transmission function.
