Creating a User Fault Subroutine
To use the user fault subroutine:
1. Create a POU.
2. In the User Interrupt Configuration window, configure this POU as a User Fault routine.
User Interrupt Instructions
STIS - Selectable Timed Start
STI0 is used in this document to define how STIS works.
Instruction Used To: Page
STIS – Selectable Timed Start
Use the STIS (Selectable Timed Interrupt Start) instruction to the
start the STI timer from the control program, rather than starting
