CPU Unit Errors
The ERH indicator will light when the ID Sensor Unit cannot operate because an error occurred on the I/O bus
to the CPU Unit or when data cannot be refreshed as a Special I/O Unit.
Both ERH and RUN Indicators Lit
The ERH and RUN indicators will light when an error occurs on the I/O bus or a WDT (watchdog timer)
error occurs in the CPU Unit, preventing data from being correctly refreshed for the ID Sensor Unit as a
Special I/O Unit. If this happens, either turn the power supply OFF and ON or restart the system. Refer
to the
SYSMAC CS/CJ-series Programmable Controllers Operation Manual
for details.
