5.6 Working with function blocks
If, for example, you have set the output QV of the AR arithmetic function
block at input I1 of the T manufacturer function block, you should connect
a CP comparator in between in order to signal the occurrence of a neg-
ative value.
In most applications, a thorough simulation is enough to prevent any impermissible
values at the function block input.
Assigning operands at a manufacturer function block's output
The following operands can be assigned to the output of a QV manufacturer function
block:
l
Markers such as MD, MW, MB,
l
or the analog output QA.
Deleting operands at function block inputs/outputs
Position the cursor on the required operand.
Press the DEL pushbutton.
The operand is deleted.
