Arithmetic function

This function extension is available from version 06.00.00!
The integrated arithmetic function allows for easy arithmetic conversion of the process
value to be written or which was read into the format of the target parameter via
parameterisable factors and without the need for an additional arithmetic FB.
 In C01093, the interpretation of the wInHWord and wInLWord inputs can be set to be
able to write to parameters:
Arithmetic mode
0 No arithmetic
(Lenze setting)
1 In16Bit:
LW=+/-32767
2 In16Bit: HW=+/-;
LW=0..65535
3 In32Bit: HW_LW=
