I have a SLC 500 (1747-L40C) in an ARPAC shrink wrapper. WWW_PLCJ－S_COM－PLC－技.术_网(可－编程控－制器技术－门户)
Weve been having issues connecting our laptop to the processor. We use RSLinx then go to the RSLogix500 program. WWW_PLC※JS_COM－PLC－技.术_网(可编程控※制器技术门户)
We use the AB_KT-2 DH-485 driver. This is the only SLC that we use that the baud rate is different. We have to change it to 9600. WWW_PL※CJS_COM－PLC－技.术_网

Anyhow, when I got to work tonight, the tech on 2nd shift was trying to connect to the SLC. WWW_P※LCJS_COM－PLC－)技.术_网
During his attempts to connect he was plugging/unplugging the connector on the front of the SLC. he said he saw a flash at one point then the CPU light started to blink. WWcW_PLCJS_COM－PLC－技.术_网

I read some of the threads in here so I think that the program got wiped out and everything is back to the factory defaults. WWW_PLCJS※COM－PLC－技.术_网(可※编程控※制器技术门户)
We do have the program backed up and also on a disc. WWW_P※LCJS_COM－PLC－)技.术_网

Ive been trying off and on for the last 5 hours to communicate with this thing so I can load the program into it but Im not having any success. WW.W_PLC※JS_C,OM－PL,C－技.术_网

I would try to reset the Slc processor to factory defaults. WWW_P※LCJS_COM－PLC－)技.术_网
Since you have a safe copy of the ladder code to download to the processor at will. P.L.C.技.术.网——可编程控制器技术门户

first of all, the SLC system that you’re working with is what we normally call a “fixed” or “brick” type system ... the User Manual for your system is here at this link ... note that this was written back in March 1996 - before RSLogix500 became the SLC programming language of choice ... so for any references to “Advanced Programming Software” (APS) that you run into, just substitute “RSLogix500 Software” instead ...

the sad thing is that I don’t think there is going to be much in that book which will help you ... I’m VERY concerned about this statement from your first post: WWW_P※LCJS_COM－PLC－)技.术_网
