Going Online with an SLC5/04

6 posts in this topic

Hi everyone, We need to get online with our client's Allen Bradley SLC5/04 to do some programming changes. Unfortunatly......SOMEONE..........has reconfigured the RS232 port as DH485 and lost their DH+ PMCIA card !!!! We cannot gain access through the RS232 port ! Any ideas ? Last resort is to remove the battery, wipe the memory and reload the program again. ANY help would be very much appreciated. Richy.

Configure in Rslinx driver for 1747-PIC /AIC+ driver since the rs232 port as DH485 you can get online with this driver once you done change to DF1

I have used rpraveenkum's idea before with mixed results, sometimes it works, sometimes not. Pick the DH485 driver and use the same cable you use for DF1. It's worth a shot.

If you have another SLC 5/04 connected via DH+, you can go to that SLC and set up a DF1-DH+ pass thru to the other SLC. There is an excellant how to posted by Ron Beaufort here: LINK

Building on Ken's idea if the SLC5/04 DH+ hits a ControlLogix Gateway or PLC you can pass thru it from Ethernet or RS232. Minimal setup required.
