4.3.2 Setting run condition
When the [Macro] check box is selected, you can enter a conditional expression and then use it
to control operation of an output port. Enter the desired conditional expression in the [Macro]
box.
-
Specify an operation condition for each output port.
-
An output port that has not been set is regarded as a port available for direct control.
-
The final value obtained from a logical operation on the listed expression becomes the
state of an output port.
-
If the operation condition expression is cleared, a port becomes available for direct
access.
-
Operation condition expressions can be specified as follows:
1) Port No. + Logic Expression (&,|) + Port No.
2) Logic Expression (!) + Port No.
3) Port No. + Logic Expression (&,|) + Logic Expression (!) + Port No.
(Logical operator "!" can only be effective before the relevant port no.)

-. Input #1 AND Input #2
I1&I2
-. Input #1 OR Output #2
I1|O2
-. The Inverse of Input #1
!I1
-. Output #2 AND Output #3 AND the inverse of Output #4
O2&O3&!O4
-
A single logical expression can contain up to 21 ports.
-
If a port is directly set to ON when its operation condition is not met, it goes into
standby state.
-
A port goes into the ON state if its operation condition is met and into OFF and standby
states if not.
-
If a port is directly set to OFF, it does not operate even if the operation condition is
satisfied.
