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)
