Parameter display and parameter set for analog value comparators:
Inputs
The function block inputs >I1, >F1, >I2, >F2, >OS and >HY can have the
following operands:
• Constants
• Markers MD, MW, MB
• Analog inputs IA01 to IA04
– IA01: terminal I7
– IA02: terminal I8
– IA03: terminal I11
– IA04: terminal I12
• Analog output QA01
• Actual value
