*1 When index number 74 (“Type of analog input”) of the service data is “0”, this designation by process output data is valid. Note
that the process input data is fixed at 0 to 10 V input for “1”, -10 to 10 V input for “2”, 0 to 5 V input for “3”, 1 to 5 V input for “4”, 0
to 20 mA input for “5”, and 4 to 20 mA input for “6”.
