Communications using RX, RY, RWr, and RWw
This function allows data communications in units of bits and in units of words between the master station and device station.
Master station and local stations
At unicast mode
1:1 communications between the master station and each local station. Local stations do not communicate with each other.
• Output from the master station
• Input from the local station
No.0, No.1, No.2: Station No.0 (master station), station No.1, station No.2
No.1, No.2: Send range: to station No.1, send range: to station No.2
No.1, No.2: Send range: from station No.1, send range: from station No.2
 The device is turned on by the sequence scan of the FX5 CPU module in the master station, and END processing is performed.
 The status data of the device of the FX5 CPU module is stored in the link devices (RY, RWw) of the FX5-CCLGN-MS by link refresh.
 The status data of the link devices (RY, RWw) of the master station is stored in the link devices (RX, RWr) of the local station by cyclic data transfer
processing.
 The status data of the link devices (RX, RWr) of the local station is stored in the devices of the FX5 CPU module by link refresh.
 The device is turned on by the sequence scan of the FX5 CPU module in the local station, and END processing is performed.
 The status data of the device of the FX5 CPU module is stored in the link devices (RY, RWw) of the local station by link refresh.
 The status data of the link devices (RY, RWw) of the local 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 FX5 CPU module by link refresh.
