I'm a trying to do a project with a Micrologix 1100 Ser A for a school project. I know a little ladder logic, but haven't ever used AB PLCs.
I purchased this one off of Ebay. First I tried to get the ethernet connected to my laptop. I tried connecting it with both a normal ethernet and crossover cable as well as to my router. The bootp server didn't show anything.
So I found a serial cable (1761-CBL-PM02) and connected it directly using the RS232 DF1 driver. I used a desktop with two COM ports to avoid USB adapter complications. RSLinx isn't showing anything - I've tried both com ports. It does seem to detect that something is connected but the auto configure always results in a timeout. Also what's odd is when I right click on my own computer and go to device properties I get an "unable to establish communications with the selected device" error. I have no clue if that means anything.
Also, there is an error on the PLC. But it's code 1 which I assume probably has something to with the program currently loaded on it. But I was having a little trouble figuring it out based on the manual.
Any tips would be appreciated. I wrote the person on Ebay but they've got like 2 weeks to respond and I'm already behind in this project. I really can't afford to lose any more days trying to figure out how to get this thing connected. It should've been much easier.
