LINE 10: Assigns the I/O pathname to the power supply.

LINE 20: Declare a common block for the I/O pathname. The COM statement must be used for the @Ps variable to preserve its value for use in the service routine.

LINE 30: Returns the power supply to its power on state, unmasks output 1’s and output 2’s OV status bits to generate faults, and enables the service request capability on all outputs.

LINE 40: Define interrupt at interface 7, with GP-IB priority 1.

LINE 50: Enable interrupt at interface 7 for service request type interrupts only.

LINE 60: Sets the overvoltage of outputs 1 and 2 to 4 volts.

LINE 70: Sets the voltage of outputs 1 and 2 above the OV setting so that both outputs will overvoltage when the program is run.

LINE 80: Waits for the computer to receive the interrupt. This simulates conditions that would normally exist when a program is running.

LINE 120: Defines the error handling routine.

LINE 130: Disables interrupt capability while processing.

LINE 140: Brings in the common block for the I/O pathname.

LINE 150-180: Conducts a serial poll. If bit 0 in serial poll register indicates a fault for output 1, output 1 is disabled and the overvoltage circuit is reset.

LINE 190-220: Checks bit 1 in serial poll register for a fault on output 2. If true, output 2 is disabled and the overvoltage circuit is reset.

LINE 230: Reads fault registers to clear FAU bits in serial poll register.
