Input and output status settings when failure occurs
For the master/local module, status of input from a data link faulty station and output status of cyclic data if a stop error occurs
in the CPU module can be set.
Status Range where the settings are enabled
Input status of data link faulty station Whether to clear or hold the following RX and RY input data can be selected.
• Master station RX
• Local station RX and RY (only the input data from other stations)
Even if "Clear" is set, input data will be held for two seconds after
communication failure such as Ethernet cable disconnection.
The RWr and RWw input data are held regardless of the setting.
• Master station RWr
• Local station RWr and RWw (only the input data from other stations)
Cyclic data output when a stop error occurs in the CPU module Whether to clear or hold the RY data (only the output data from the own
station) of the master station and local station can be selected.
