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 (N/O 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 (N/O contact) switches to status 1, if the value on
>I1 is equal to the value on >I2; >I1 = >I2.
• CP01GT to CP32GT, (greater than)
Contact (N/O contact) switches to status 1, if the value at
>I1 is greater than the value at >I2; >I1 > >I2.
Memory requirement of the counter relay
The comparator function block requires 32 bytes of memory
plus 4 bytes per constant on the function block inputs.
CP02 +

>I2
CP02 Analog value comparator function block number 02
+ Appears in the parameter display
>I1 Comparison value 1
>I2 Comparison value 2
