7.5.2 Arithmetic blocks
Purpose
With the arithmetic blocks two different signals can be arithmetically connected to
meet different application requirements.

1. Inputs
With the function ”freely assignable analog inputs” each input can be assigned to
a ”terminal signal” from the table in C145. If signals are assigned to the inputs, the
input codes are for display only. If the inputs are not assigned, constant values can
be assigned via the input codes. These values can also be save via C003.
2. Outputs
With the function ”freely assignable analog inputs” (see code C146), arithmetic
block outputs (signal sources) can be assigned to certain targets. If the arithmetic
block is assigned to another input or code, the access to this code via keypad or
interface is no longer enabled.
The output signal is limited to max. 200%.
The arithmetic blocks can also be output via the monitor output as analog voltage.
