I am troubleshooting a communications error problem. I responded to a blinking fault light on my
SLC 500 1747-l532 Series D Processor unit. After much deliberation drew the conclusion that the program was screwed up. Thankfully I had a backup copy on lap top made few years ago for just such an occasion.
I created a driver setup with rslinx Classic:
DH485 Sta:0 COM1
Comm Port COM1
Device SLC-CH0/Micro/Panelview
Baud 1200
Station 00
Parity NONE
Error Checking NONE
Stop Bits 1
Protocol FULL DUPLEX
Communications with the PC from lap top was good and a successful download of the backup program happened and the SLC 500 is now online and back in control of the assembly line.
My current issue is during the download there was a popup that said something to the effect “If I choose to continue communications will be interrupted click to approve. Now Rslinx does not see the SLC500 using same profile and cable. There are some additional timing edits I need to adjust but seems to be locked out.
