alarm code in the remote I/O mode or remote I/O mode 2.
In the position/simple direct mode, a simple alarm code is output to input address n+2.
In the half direct mode or full direct mode, an alarm code is output to input address n+6.
[1] Check the alarm code using the PLC’s monitor function, etc., or connect the RC PC software or teaching
pendant and check the code on the status monitor screen.
[2] Use the identified alarm code as the key to search the alarm list provided in the operation manual for the
controller.
