Dedicated Instruction
Instruction Description
RIRD Reads the specified points of data from the buffer memory or the device in the CPU module of
the target station.
RIWT Writes the specified points of data to the buffer memory areas of the target station or the
device in the CPU module of the target station.
RIRCV Automatically performs handshaking with the intelligent device station and reads data from
the buffer memory areas of the specified intelligent device station.
Available for communication with modules that have signals for the handshake, such as
AJ65BT-R2N.
RISEND Automatically performs handshaking with the intelligent device station and writes data to the
buffer memory areas of the specified intelligent device station.
Available for communication with modules that have signals for the handshake, such as
AJ65BT-R2N.
RIFR Reads data from the automatic update buffer of the intelligent device station or the random
access buffer.
Available for communication with modules that have the automatic update buffer, such as
AJ65BT-R2N.
RITO Writes data to the automatic update buffer of the intelligent device station or the random
access buffer.
Available for communication with modules that have the automatic update buffer, such as
AJ65BT-R2N.
RDMSG Reads/writes parameters from/to the remote device station and reads the status of the remote
device station.
Available for communication with the remote device station that supports the message
transmission function, such as NZ2AW1C2AL.
RLPASET Sets the module parameters to the master station and starts up the data link.
