Explanation of example
The self−diagnosis error 100 is set when the execution condition (trigger) R0 turns on. For
FP0/FP−e/FP0R/FPΣ/FP−X, the ERROR (ERROR/ALARM) LED on the control unit blinks and for
FP2/FP2SH/FP10SH, ERROR LED on CPU lights, and operation stops.
(If a situation occurs in which you wish to set the self−diagnosiserror 100, set up the program so that input R0
turns on.)
When the execution condition (trigger) R1 turns on, self−diagnostic errors of error codes 43 and higher are
cleared.
