2.7.19 LOGIC C
The Logic C module executes a selected function on two input variables A and B to produce an out-
put. Input variables A and B, as well as the output, are all logic values (0/1). The table below lists
the input variables; an illustration of the Logic C module follows the table. The function code (FC)
to be executed by the Logic C module is selected from the Logic Functions table at the bottom of
the page and entered into datapoint B172.
