Appendix C Error Codes
RSLogix 500 Error Report
Example
In this example, Offset 1=9 is invalid.
To learn what the error code means, follow these instructions.
1.
Download the project to the controller.
In this case, it is the MicroLogix 1500 controller.
2.
Place the controller in Run mode.
The controller’s fault indicator blinks red.
3.
In the software, choose Fault from the pull-down menu in the upper left
corner.
Choosing Fault provides the status window with error code 179h.
4.
In the project space, choose Controller>Function Files>IOS tab.
This IOS tab corresponds with the module number in the rack and returns
the error number. The RSLogix 500 software explains the error.
IMPORTANT
If a 1769 I/O module fault occurs, you must cycle power to the controller after
clearing the major fault. I/O communication is not restored until after the
power cycle.
Never use the fault handling routine to clear local I/O faults. Clear local I/O
faults manually on a per instance basis, and then cycle power to the controller.
