INTSUSPEND - Suspend Interrupts
All of the BRX PLCs and BRX HSIO modules (BX-HSIO1, BX-HSIO2) support hardware interrupts and timed events that can be used to initiate the execution of an Interrupt Service Routine (ISR). These interrupt events must be programmed through an Interrupt Trigger that specifies the type of trigger with the required triggering conditions, and which Interrupt Service Routine to execute when that trigger is fired.
The Suspend Interrupt instruction stops normal processing for ALL of the Event, Register Match, and Timer interrupts. Any hardware or timer interrupts that occur while the interrupt processing is suspended will be lost.
Input Leg selects which of the following power-flow conditions will cause this instruction to run:
- Edge Triggered
means the instruction will run to completion each time the input ladder logic
transitions from OFF to ON.
- Power flow enabled means the instruction will run repeatedly as long as the input ladder logic remains ON.
