10.4 Operator error
Operator errors events
Operator errors develop as a result of improper operation of the module caused by the
incorrect input of control signals.
Objects which indicate operator errors
FC CNT_CTL1 enter the operator error numbers in the DB. FC CNT_CTL1 sets output
parameter OT_ERR to indicate the occurrence of an operator error. You can access this
data word in your program using the variable identifier `OT_ERR_B'.
