Stores the input data (word unit) sent from the slave station to the master station (FX5-ENET) with cyclic transmission.
Remote register (RWw)
■Remote register (RWw) (Un\G3024 to Un\G4047)
Set the output data (word unit) to be sent from the master station (FX5-ENET) to the slave station with cyclic transmission.
Cyclic transmission status of each station
■Cyclic transmission status of each station (Un\G4100 to Un\G4101)
Stores the slave station cyclic transmission state for each station No.
• Only the bit of the start station number turns on.
• The status is not stored for the reserved stations and the station numbers after the maximum station

• Use this buffer memory as an interlock for cyclic transmission. (Page 39 Interlock Programs of Cyclic
Transmission)
