Parameter display and parameter set for the comparator
function block:
Inputs
The function block inputs
>I1 and >I2 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
… QV> of another function block
Contacts
• CP01LT to CP32LT, (less than)
Contact (make contact) switches to status 1, if the value on
>I1 is less than the value on >I2; >I1 < >I2.
• CP01EQ to CP32EQ, (equal to)
Contact (make contact) switches to status 1, if the value on
>I1 is equal to the value on >I2; >I1 = I2.
• CP01GT to CP32GT, (greater than)
