2.7.38 LOGIC H

The Logic H 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 H module follows the table. The function code (FC)

to be executed by the Logic H module is selected from the Logic Functions table at the bottom of

the page and entered into datapoint B239. The function codes are also provided in expanded form

on the next page.
