If a CPU module installed together with the CC-Link IE Controller Network
module with external power supply function 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.
( Page 275, Section 8.1.3)
When group cyclic transmission is used, a station whose shared group is
different from the group of the own station is detected as a cyclic transmission
error station. (Including reserved stations)
(Condition)
• Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error is held.
• The station No. later than the largest one are excepted.
