Note: Always 1.
Read data
Comparison Operator
0: ≤ (Comparator bit turns ON when
8-digit counter PV ≤ Comparison data 2.)
1: ≥ (Comparator bit turns ON when
8-digit counter PV ≥ Comparison data 2.)
[STX]000000101CA000002001 The bit position is specified when reading. In
this example, the bit 02 is specified when
reading the status of Work Bit M2.
[STX]00000010100000000001 The response says that the specified Work
Bit is ON (1).
