I'm New here. Lots of good info here. Look forward to learning. Did some searching for help with a problem I have but did not find anything yet.
Using a Siemens 810M under the General Numeric Brand Name. About 17 years old hooked to a Motion Masters CNC Router. Using BeachCam to upload/download data. (Old DOS based but it works)
About 16 months ago we lost the ability to download from the controller to the computer. Everything else worked fine. Now the Upload does not want to work. (Everything else appears to still work just fine.) Literally I left one evening with it working and the next evening it did not. Machine was shut off the time in-between.
Any tips on troubleshooting this? We have used the same cable, same software and same communication specs all along. I have already rung out the cable along with its jumpers. I am pretty sure the computer's I/O port is working. My only positive clue that the controller may be talking to the computer is at one point i had the controller in "data in" mode (DIO) and shut the computer off. I immediately received an alarm at the controller.
I do have a call into Siemens but so far nothing from them.
Any ideas? I plan to get a Serial port checker to be 100% certain on the computer end. I have no problem getting into the computer to ring things out. Will ring out the 25 Pin D-Sub next. Have access to electrical test equipment if there are any ideas out there. If need be I can post the communications specs on the PC end as well as the controller end.
Thank you for the help.
