Automatic Recovery to Duplex Operation by Self-diagnosis
Note
After the mode has been switched from Duplex Mode to Simplex Mode due to
an operation switching error or a duplex error, an automatic attempt is made
to return to Duplex Mode if this function has been enabled in the PLC Setup.
This function is mainly useful for momentary or incidental disruptions (to
memory, bus, etc.) due to factors such as noise, rather than for hardware
breakdowns.
When this automatic recovery function is executed, it does not return standby
status to active.
