Compatibility of AC010 devices with logic relays

New functions were added to the parameter display of the
CL-LSR/CL-LST and CL-LMR/CL-LMT. The AC010 parameters
can be found at the following points.

h
The analog comparator of the CL-LSR/CL-LST and CL-LMR/
CL-LMT operates internally in the value range:
–2147483648 to +2147483647
This ensures that the correct value is always calculated.
This is important for multiplying values (I1 × F1 or
I2 × F2).
Example:
I1 = 9999, F1 = 9999
I1 x F1 = 99980001
The result is within the value range.
h
If no value is entered at F1 or F2, only the value at I1 and
I2 is used (no multiplication).
h
If the value of a counter relay exceeds the value 9999, the
value of the counter is shown in the display of the analog
value comparator minus 10000.
Example: Counter actual value =10233
Display of the analog value comparator: 233 (10000 is
displayed as 0).
