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.
Function of the function block
The function block creates the operation depending on the operating mode.
