Hello everyone.
I'm not overly familiar with PLCs. I know how to read through them and adjust them and do some minor programming, but other than that, I'm new to them.
Anyway, I've been sent to a jobsite, to correct a few mechanical issues and one PLC issue. I've used the ladder logic at this job site - I was actually the first one to upload it - many times without issue, so I know the processor and laptop are compatible.
Most times I travel with a programmer or I have the code to just upload. This time though, I need to get on to the processor, download the current program, and change one line in the code.
My problem is, that I cannot get my laptop to recognize the processor. It keeps looking for the last project I worked on (different site all together) and coming back with a "No response from processor" error.
I've done some searching online, and I'm going to go through this webpage tomorrow:
Just wondering if there is something simple I'm overlooking or if there is a more complicated issue causing this problem. Normally I'd be able to call back to the office, but the only one who would know is away and not available (hence sending a virtually useless programmer to site).
Cheers and thanks for any help.
