A custom function was written for counting pulses from the ncoder via FM350-1 counter Module. It works most of the times, however sometimes the output "ErrorNotify" from the function is high. At this time "ErrorType =2" and "INTErrorCode = 5" which means the FM350-1 module gives out Operator Error with description "only Parameter Assignment control bit may be set". Once this error occurs it cannot be acknowledged using OT_ERR_A bit. System is shutdown untill the error is resolved. The problem gets solved after sometime automatically. The pulses from encoder are counted by the module during this error, however "SetCount Zero" bit is high and it does not reset the internal counter of the module. The PDF copy of this function is attached herewith. Can anyone help finding error in this function which causes this problem infrequently? The counter module FM250-1 was also replaced, still the problem repeats infrequently. Note: M0.0 in this function is defined as always false signal in PLC.
