Inputs:
With the function ”freely assignable inputs” each analog input of the comparator
can be assigned to a ”terminal signal” from the table according to C145. The input
values are compared in the range of  200 %.
With the function ”freely programmable digital inputs”, the reset input can be
connected with a signal source according to the table under code C112.
”Analog” output:
With the function ”freely assignable inputs” the inputs C580 for comparator 1 and
C590 for comparator 2 can be used for further processing tasks. It is possible, for
example, to compare the signal at the analog input terminal 8 with a limit value and
provide the main set-value.
”Digital” output:
With the function ”freely assignable digital outputs”, the result of the comparator
can be assigned to an output according to the table under C116.
