Problems with processor SLC 5/04

[stefan2821]

I'm using a processor SLC 5/04 with DH+ interface (1784-U2DHP), I see that I'm connected, but when I want to go online or download the program I have an error: Corrupted processor! What can I do??
Thanks!

Try going thru the serial port using a DF1 connection, see if the DH+ parameters are correct and match your programming tool.

I've checked the parameters for DH+ and are the same in all parts (RSLinx and COM port). In this moment I don't have a serial cable, but I'll buy one and see if is going...

This error can be solved by installing a new version of RSLogix 500 (v7.2) and RSLinx (v2.57).

If all else fails, the serial link is always the backup.

I vaguely remember a similiar problem with a SLC5/04. I had one that was running a program but like you whenever I tried to down load the program I received the corrupted message yet I knew the processor was running properly. I remeber that it was finally resolved by contacting my local AllenBradley distributor which was able to find the older version of the software which was able to view the processor. Maybe if you contact AllenBradley they might be able to look it up and send you the older version to try out. I think there was an issue with one version of the older software that once a program was downloaded to the PLC with that version it could not be downloaded with later versions.

@Dave. Yes, the problem was solved by installing the new version of RSLogix and RSLinx. After that, everything works ok.
