The Setup program can be used to carry out two
mathematical calculations or logical combinations of
various signals and process variables from the
controller. The formula is created by means of a
formula editor.

With math formulae, the calculated result is presented
through the two signals „Math 1“ and „Math 2“ of the
analog selector. With logic formulae, the result of the
logical combinations is available through the signals
„Logic 1“ and „Logic 2“ of the binary selector when
configuring the binary functions.
