Troubleshooting Methods
There are three methods to verify the content of an error should one occur in
the system: from the phenomenon, by error code, and by the monitor function
of a peripheral device. The causes can be quickly verified by using each of
these methods in accordance with the situation.
Phenomenological Verification
This is the execution of causal analysis and recovery by observing the LED
display on the front of the module and the operational status of each device.
Verification by Error Code

code upon error generation. Errors are classified into the following types:
