Communications Using Rx, Ry, Rwr, And Rww - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Communications using RX, RY, RWr, and RWw

This allows data communications in units of bits and in units of words between the master station and device station.
Master station and remote stations
■At unicast mode
1:1 communications between the master station and each remote station. Remote stations do not communicate with each

• Output from the master station
 The device of the CPU module turns on.
 The status data of the device of the CPU module is stored in the link devices (RY, RWw) of the master station by link refresh.
 The status data of the link devices (RY, RWw) of the master station is stored in the link devices (RY, RWw) of each remote station by cyclic data transfer
processing.
 The status data of the link devices (RY, RWw) of the remote station is output to the external device.
• Input from the remote station
 The status data of the external device is stored in the link devices (RX, RWr) of the remote station.
 The status data of the link devices (RX, RWr) of the remote station is stored in the link devices (RX, RWr) of the master station by cyclic data transfer
processing.
 The status data of the link devices (RX, RWr) of the master station is stored in the devices of the CPU module by link refresh.
