Conditional Branch - Omron FH-3 Series Reference Manual

Set
Expression A
Expression B
YES
Destination unit
NO

Conditional Branch

Specify expression A and B for the branching conditions.
1
Set expression A and B separately.
Reference: Layout of Setting Expression Window (p.621)
2
Click [icon] to set up conditions.
Condition
If the value from expression A is equal to that from expression B, moves to the unit in which
A=B "Destination unit" is YES.
If not, moves to the NO unit.
If the value from expression A is equal to that of expression B, or if the value of A is lower than that of
A<=B
B, moves to the unit in which "Destination unit" is "YES". If A is larger, moves to the unit with "NO".
If the value from expression A is lower than the value from expression B, moves to the unit in which
A<B "Destination unit" is YES.
If A is equal to or greater than B, moves to the NO unit.
If the value from expression A is equal to that of expression B, or if the value of A is higher than that of
A>=B
B, moves to the unit in which "Destination unit" is "YES". If B is higher, moves to the unit with "NO".
If the value from expression A is higher than the value from expression B, moves to the unit in which
A>B "Destination unit" is YES.
If A is equal to or less than B, moves to the NO unit.
3
Set the branch destination.
Important
• In order to avoid measurement processing looping, for the branch destination, set a processing unit number that
is after the [Conditional Branch].
• Make sure to set "End" at the last branch destination to indicate the end of the branch.

Description
Set the evaluation expression that is to be the basis for
branching. Set the expression through calculation.
