Major faults Chapter 1

This section provides the steps for creating a fault routine to operate as the

controller fault handler. Program tags are automatically created during this

process.

Important:

When you program the fault handler, remember that any instruction that is skipped as part of the fault-

handling program does not run when the main tasks and associated programs run.

For example, if your fault handler skips a JSR instruction that is causing a major fault, then that JSR

instruction, including all of the programming within the subroutine, does not run.

When an instruction generates an error due to a fault (for example, a COP with an indirect addressing

programming error), the instruction is skipped and does not run. This occurs with all instructions.

1. In the Controller Organizer, right-click Controller Fault Handler and

choose New Program.

2. On the New Program dialog box, in the Name field, enter a program name.

Verify that the Schedule in field is set to Controller Fault Handler.

3. Click OK.

Create a routine for the

Controller Fault Handler
