2.7.28 MATH E

The Math E module executes a selected function on three input variables A, B, and C. The func-

tion to be executed by Math E is selected by entering a Function Code (FC) in datapoint B204. Nu-

meric values for parameter constants K1, K2, and K3 can also be entered into their respective

datapoints, which may affect the output as determined by the function code selected. The output

can be a numeric (C035) and/or a logic (L088) value.

The tables that follow list the input variables, parameters, and function codes. An illustration of the

Math E module follows the tables.
