h the uncontrolled master station is not performed.
Specifying the number of occu
pied stations that cannot be ha
ndled
When the master station specifies the number of occupied stations that cannot
be handled by the SJ-Ether, the relevant bits are turned on.
Communication with the master station is not performed. The system is in th
e unlocked state.
High load conditions
When the load on the CC Link IEF Basic communication process is large an
d there is a fatal problem with the main scanning process of the PLC, the rel
evant bits are turned on.
Communication continues.
