How do I lock out a switch based on a condition?

Published date: 23 August 2019

Issue:
Looking for a way to prevent or lock out a switch with a PLC status bit.

Product Line:
Vijeo Designer (all versions)

Resolution:
In Vijeo Designer, the switch object has an Interlock property that can be set with a specific condition. Until the condition is true, the switch will not execute its defined operation. 

To configure the switch, double click on it to bring up the Switch Settings dialog.

1) Click on the Advanced Tab
2) Check the "Enable Interlock" checkbox
3) In the field, either create an expression or assign a BOOL variable.
4) Press OK.

Now the switch is deactivated until the condition or BOOL variable is true.
