Part Number Decoder | MicroLogix 1400 controller 1766L32BWA
Decoded from the Rockwell Automation catalog-number structure. Series and firmware revision are printed on the product label, not encoded here. | ||||||||
Series & Revisions | Series B in stock; other series on request. Series notes: A later series runs the existing program after the processor type is changed in RSLogix 500. An earlier series may not if the program uses features from a newer OS/FRN. | ||||||||
Intended Use | Intended for small standalone machine and remote-site control applications. MicroLogix 1400 controllers run pump stations, lift stations, small packaging and OEM machines and remote telemetry panels, with built-in Ethernet, serial ports, a front LCD and data logging in a brick-style unit expandable with 1762 I/O. | ||||||||

Fault code reference
1766-L32BWA Fault Codes
44 codes · 1766-RM001
Fault codes a MicroLogix 1400 controller reports on the controller LCD and status word S:6 in RSLogix 500 / RSLogix Micro (hexadecimal), as documented in Rockwell Automation publication 1766-RM001. Use them to narrow a problem down to the unit, its wiring or the application before sending it in for repair.
| Code | Fault | What it indicates |
|---|---|---|
| 0001 | NVRAM error | Program memory was corrupted (power loss during download, noise, failing battery) and the default program was loaded. |
| 0002 | Unexpected reset | The controller reset unexpectedly due to noise or an internal hardware failure; the default program is loaded. |
| 0003 | Memory module program corrupt | Memory module memory error; can also appear when going to Run mode. |
| 0004 | Memory integrity error | ROM or RAM became corrupt at power-up or during the background integrity check. |
| 0006 | Memory module hardware fault | The memory module hardware faulted or is incompatible with the operating system. |
| 0007 | Memory module transfer error | Failure during memory module transfer. |
| 0008 | Fatal internal software error | Unexpected software error; cycle power and reload the program. |
| 0009 | Fatal internal hardware error | Unexpected hardware error; cycle power and reload the program. |
| 000A | OS missing or corrupt | The operating system required for the user program is missing or corrupt. |
| 000B | Base hardware fault | The base hardware faulted or is incompatible with the operating system. |

Where the manual's only remedy for a code is to replace the unit or module, the code is pointing at a hardware fault inside that part. Those are the faults NJT Automation repairs at component level, so a repair quote is usually the first thing to check before buying a replacement.
