Precautions for the PLC link communication function
• When the PLC link communication function is used, RS-485 communication
with the host device cannot be used.
• Do not connect anything other than the C1M and one PLC unit to the RS-485
communication line.
• Set the C1M addresses from 1 to the maximum number of connected C1M units.
The maximum number of connected C1M units can be selected from 8 (default),
16, 24, and 31.
• The PLC’s device ID and the C1M’s station address must be different.
• Do not use 255 or 254 as the device ID of the PLC.
• New settings will apply after the power of the device is turned off and back on. If
you have changed the settings, turn the power off and back on.
• Use the required number of consecutive registers on the PLC.
• Different protocols cannot be used at the same time.
