Description

Probable Cause

Recommended Action

xx55

A discrete I/O module required for the user
program is detected as having the wrong
I/O count.

This code can also mean that a specialty
card driver is incorrect.

If this is a discrete I/O module, the I/O
count is different from that selected in
the I/O configuration.

If this is a specialty I/O module, the card
driver is incorrect.

If this is a discrete I/O module, replace it
with a module having the I/O count
selected in the I/O configuration. Then,
clear the fault and run, or

change the I/O configuration to match
the existing module, then reload the
program and run.

If this is a specialty I/O module, refer to
the user manual for that module.

xx56

The rack configuration is incorrect.

The rack configuration specified by the
user does not match the hardware.

Correct the rack configuration, reload the
program and run.

xx57

A specialty I/O module has not responded
to a Lock Shared Memory command within
the required time limit.

The specialty I/O module is not responding
to the processor in the time allowed.

Cycle rack power. If this does not correct
the problem, refer to the user manual for
the specialty I/O module. You may have to
replace the module.

xx58

A specialty I/O module has generated a
generic fault. The card fault bit is set (1) in
the module’s status byte.

Refer to the user manual for the specialty
I/O module.

Cycle rack power. If this does not correct
the problem, refer to the user manual for
the specialty I/O module. You may have to
replace the module.

xx59

A specialty I/O module has not responded
to a command as being completed within
the required time limit.

A specialty I/O module did not complete a
command from the processor in the time
allowed.

Refer to the user manual for the specialty
I/O module. You may have to replace the
module.

xx5A

Hardware interrupt problem (“stuck”).

If this is a discrete I/O module, this is a
noise problem. If this is a specialty I/O
module, refer to the user manual for the
module.

Cycle rack power. Check for a noise
problem and be sure proper grounding
practices are used. If this is a specialty I/O
module, refer to the user manual for the
module. You may have to replace the
module.

xx5B

G file configuration error – user program G
file size exceeds the capacity of the
module.

G file is incorrect for the module in this slot.

Refer to the user manual for the specialty
I/O module. Reconfigure the G file as
directed in the manual, then reload and
run.

xx5C

M0–M1 file configuration error – user
program M0–M1 file size exceeds capacity
of the module.

M0–M1 files are incorrect for the module in
this slot.

Refer to the user manual for the specialty
I/O module. Reconfigure the M0–M1 files
as directed in the manual, then reload and
run.

xx5D

Interrupt service requested is not
supported by the processor.

The specialty I/O module has requested
service and the processor does not
support it.

Refer to the user manual for the specialty
I/O module to determine which processors
support use of the module. Change
processor to one that supports the module.

xx5E

Processor I/O driver (software) error.

Corrupt processor I/O driver software.

Reload program using A-B approved
programming device.
