I have a SLC 500 (1747-L40C) in an ARPAC shrink wrapper. Weve been having issues connecting our laptop to the processor. We use RSLinx then go to the RSLogix500 program. 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. Anyhow, when I got to work tonight, the tech on 2nd shift was trying to connect to the SLC. 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. 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. We do have the program backed up and also on a disc. 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. I would try to reset the Slc processor to factory defaults. Since you have a safe copy of the ladder code to download to the processor at will. You can find the procedure on page # 1-11 (pg27 of 291) At http://literature.rockwellautomatio...um011_-en-p.pdf 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: | |
