Wiring of the function block
An arithmetic function block does not require an enable or
start signal and is therefore not wired in a coil field of the
standard circuit diagram. The function block is provided with
the two Boolean outputs mentioned above for controlling
the calculation result that you wire as contacts in the
standard circuit diagram. Example of an arithmetic function
block:

Wiring the function block contacts
Parameters
When using the function block in the circuit diagram for the
first time, use OK to automatically enter the general display
of function block parameters, as shown in the figure on the
left. Enter the function block settings here. The display
contains the following elements:
