Posted 6 May 2016 I hope to be able to provide more information, but for now this is what I have. I have a SLC5/05 that faults whenever a graphic display is pulled up from a Cimplicity HMI. So, the PLC is not faulted while all harnesses are connected to the I/O modules, and while the Ethernet cable is plugged in, but it appears to fault when a corresponding graphic is called up that includes tags from the particular processor. There are two PLCs on the network, and I am not certain if they share data between each other or not, or if the data is just being shared to a common Cimplicity HMI. Another strange thing is that one of the PLCs on the network is using a MSG instruction to pull data from what appears to be the PLC that continues to fault, but the IP address configured in the MSG instruction does not match.

Posted 9 May 2016 Go online with the SLC, make the fault condition occur (by pulling up the Cimplicity HMI screen), then drill into the SLC properties to find out exactly what the fault condition is. Do you know how to pull up the processor properties to determine the fault code? http://besser.com/uploads/support/SB02-4.pdf Share this post Link to post Share on other sites
Posted 9 May 2016 Thanks Kaiser. I know how to pull up the fault code from the processor properties. Thanks for the comprehensive SLC-500 error codes service bulletin. Share this post Link to post Share on other sites
