nIn1_a Integer analog VAR_INPUT Addition input

nIn2_a Integer analog VAR_INPUT Addition input

nIn3_a Integer analog VAR_INPUT Subtraction input

nOut_a Integer analog VAR_OUTPUT Signal is limited to ±32767.

Functional sequence

1. The value at nIn1_a is added to the value of nIn2_a.

2. The value of nIn3_a is subtracted from the calculated result.

3. The result of the substraction is then limited to ±32767.
