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).
