Description
Stores the cyclic transmission status of each station (including
the host).
0: Executing cyclic transmission (including the station with
the maximum station number and smaller number as well
as reserved stations)
1: Cyclic transmission not executed

If a CPU module installed together with QJ71LP21S-25 is turned
OFF, detection of a data link error may take more time than
usual.
For immediate detection of a data link error, program an interlock
using the link relay (LB) in each station's send range.
For details, refer to the Q Corresponding MELSECNET/H
Network System Reference Manual (PLC to PLC network).
Stores the parameter communication status of each station.
0: Executing communication other than parameter
communication (including the stations with the maximum
station number and smaller numbers as well as reserved
stations)
1: Executing parameter communication
