Table 2.2
2.4 Method of use
The counter states of the -1502 module are all represented by 4 bytes, and
the total number of bytes is represented by the total number of 4 states, which
are channel 1, count, channel 2 count, channel 1 frequency and channel 2
respectively
For example, when GC-1502 module is connected to PLC-400, four states
can be used as four IO variables and represented by four UDINTs.
Channel1Cnt AT % I0.0: UDINT; Channel2Cnt AT % I4.0: UDINT;
