The function block inputs I1 and I2 can have the following
operands:
• Constant.
• Markers MD, MW, MB.
• Output
…
QV> of a different function block.
Contacts
The contacts of the function block are evaluated in the
standard circuit diagram. A closed contact indicates:
Memory requirement
The function block requires 32 bytes of memory plus 4 bytes
per constant at the function block inputs.
Operation of the function block
The function block compares values present at the inputs >I1 and
>I2.
The following contacts close depending on the comparison result:
• >I1 greater than >I2, GT closes.
• >I1 equal to >I2, EQ closes.
• >I1 less than >I2, LT closes.
Parameters
Function, parameterisation in the function
block
CP..LT
>I1 less than >I2
CP..EQ
>I1 equal to >I2
CP..GT
>I1 greater than >I2
