Inputs
I1 and I2: At function block inputs I1 and I2 you write the values to be
associated. You can assign the following operands to function block inputs
I1 and I2:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
•
Analog output QA01.
•
Output
…
QV of a different function block.
Output
The output
…
QV> supplies the operation result. You can assign the following
operands:
•
Analog output QA01.
•
Markers MD, MW, MB.
