10/8 · And if you pull a processor out and put it back in under power, most of the time (in my observation) you will fault and have the default program show up. However, the serial port

1. The processor has Major Faulted. This is usually a programming error that has caused the processor to shut-down in the major fault state to 

1747-L551, 5/05 Processor Module (16K), Series B, Processor Revision 4, Functional Issue – These processors will fault when set to the RUN mode.

Backup options for increased fault tolerance through the ControlNet™ Hot Backup module or the PLC-5 Backup Communication module The SLC™ 500 control system migration is part of the proactive modernization plan we have for you. As our SLC™ 5/01, 5/02 and 5/03 8K series controllers are discontinued and no longer available for sale, to

SLC 5/03, SLC 5/04, and SLC 5/05 Modular Processors Catalog Numbers 1747-L531, 1747-L532, 1747-L533, 1747-L541, LED indicator on the power supply should be on and the fault

Posted 14 Jul 2010. Affected modules include 1747- L54X and 1747-L55X modules with date codes between 0504 and 0805 (May 2004 to August 2005). I do not think this one qualifies, however, it still sounds like the problem. I would call AB and see what happens. Posted 15 Jul 2010.

Solid Fault Light - This means that the PLC has a hardware issue. There is no recovering from this and the PLC will have to be replaced.

2022/3/16 · Instead of a DH-485 port, the SLC 5/04 has a built-in DH+ port for communication with other SLC 5/04 and PLC processors, operator interfaces, and programming terminals. Communication via the DH+ network is three times faster than DH-485 communication. SLC 5/05 processors provide a 10/100BASE-T, 10 or 100 Mbps Ethernet port.

BUENAS TARDES A TODOS. EL DÍA DE HOY ME SUCEDIÓ QUE AL IR A REVISAR UN SLC 5/02 SE ENCONTRABA EN FAULT LA CPU.
