Understanding Interrupt Routines 11-7
Subroutine File 5 - Executed for Error 0034h
If the accumulator value of timer T4:0 is negative, the major error halted bit,
S:1/13 is unlatched, preventing the processor from entering the Fault mode.
At the same time, the accumulator value T4:0 ACC is cleared to zero and
output O:2.0/0 is energized. Fault code 0034h is displayed in the status file.
If the preset of timer T4:0 is negative, S:1/13 remains set and the processor
enters the Fault mode (O:2.0/0 will be reset if previously set). Also, if either
the preset or accumulator value of any other timer in the program is negative,
S:1/13 is set and the processor enters the Fault mode. If previously set,
O:2.0/0 is reset.

The following rung toggles an output every time an error code of 0034h has occurred in the processor assuming the reason for the error
was a negative value in timer T4:0.
The following run returns program execution back to the main program.
