Communication Specification - Toshiba TOSVERT VF-AS1 Function Manual

4.4. Communication specification

This option occupies one station area of the buffer memory of the PLC.
There are remote I/O (RX, RY both 32 bits) and the remote register (RWw, RWr both 4
word) in the communication data for one station area.
