Description
Checks the hardware inside the CC-Link IE
Controller Network module.
Checks the hardware of the communication circuit
of the CC-Link IE Controller Network module.
Checks the network cable connection status, line
status, and each station's parameter setting status
from the control station.
Checks the condition of the cable connected
between two stations (from OUT of the executing
station to IN of the other station.)
Checks if transient transmission data can be
properly routed from the own station to the
communication target.
Checks whether there is an error in the
communication route when the IP packet transfer
function is used.
Description
When a CC-Link IE Controller Network module of
the control system CPU detects a data link error, it
issues a system switching request to the control
system CPU.
