My CPU 534 14B doesn't work. Run led flash 7 times. no possible MB+ connection, ERROR code meanings: 300 EXEC not loaded or 301 EXEC Checksum. It was working well then nothing can't even communicate with it. reset power without battery, download an other firmware (EXEC) 1.11 instead of 1.16, same problems. Someone can help on that case? I'm using NXT as programming software.

Hello all, first post here, and thanks in advance for the help. I'm a fairly green SCADA and controls designer and although I worked fairly extensively with these systems in the past, I followed a sightly different career path for the last several years and haven't had my hands on a PLC that whole time. Started a new job and am rebuilding my knowledge with it. Fortunately my company afforded me a PLC to take home and mess around with for this purpose. I feel pretty dumb as I am struggling to even connect with it, haha. Here are the stats: Backplane: TSXRKY4EX (end caps are securely in place) Power supply: TSX PSY2600 Processor: TSX P57 6634 First I attempted to connect via ethernet, using the IP address sticky-noted to the front of the processor: 10.1.1.80. No luck, "PLC address is incorrect, or PLC is busy, yadda yadda". As I understand, the default IP address can be converted from the MAC address. The last two MAC address numbers were: CF.87, which gave me the address 85.16.207.135. Same result with this. I tried pinging both address from the command console and had no luck there either. I happened to have a USB to unitelway adapter (Telemecanique brand) and attempted using that as well, Address:SYS.. Media:Unitelway. No luck, same answer. After a lot of frustration and hours spent scouring the internet for answers, I took the nuclear option and pulled the battery (while unplugged) and replaced after 30 or so seconds. I was assuming this would clear the memory and reset the IP to default (85.16.207.135), afterwhich I could reconfigure and start fresh. Unity still can't connect nor can I ping it. It should be noted that I am using Unity Pro XL Version 8.0, on a VMware image. I did attempt pinging from both the VM and the host machine, both can ping other known devices so connection by the VM through the host shouldn't be the problem. Neither the VM or the host recieved a ping reply from the PLC. Any help would be GREATLY appreciated. I feel I have exhausted all options and I hope I didn't shoot myself in the foot by pulling the battery. As far as whatever program was on it before is irrelevant, the PLC was given to me to do with whatever I wish, so memory loss wasn't a danger. I just need to connect to it. Thanks!!
