The vendor is supposed to be getting a 'refurb' unit together for the customer for $$$$, but I have seen several on ebay for +/- $200
So then, if that's the case would you expect that any of these PLC's of the same vintage will have the same issue?
Is his ship sinking?

Anyone out there familiar with the Telemecanique Modicon TSX Nano 07 series of logic controllers? This PLC is installed in a bindery machine and a few weeks ago it failed, error LED on, no activity.

Externet, I have been following this thread, and added a few comments, but the question now is... Why do you want to measure this minuscule magnetic field? I would think that the earth's much larger magnetic influence, and the clutter all else around this magnet's minor field, would swamp it complet...

Years ago it was purported that they could tell what was being typed on an IBM Selectric typewriter by the line current pulses from the motor related to the mechanical movements. After the enginers went the limits with filter and suppression ideas, some tech hung a flywheel on the motor shaft an the...

OK, Here's the deal Get an old CRT TV, place it near the magnet, use wireless linking of a video camera looking at the CRT screen to your remote location, and observe the color distortion caused by the magnet to confirm movement. Use a hall effect switch, and a siren on the roof. OR.. we could work ...

I shipped years of the tabloid sized N&V to another member years ago.
Do I miss them....except for the nostalgia value, not too much.

Hi, No compression or encryption. It is an older Maxtor network drive. All systems and software have no problem accessing the files. I feel it is because it is a network drive and maybe here once was a version to handle file sharing and locking. I am not tying to use multiple users, just to access t...

Hi Dale,
I'll try that tomorrow but I suspect it will be the same. The file associations work because clicking the file in the NAS file launches the data base program, then it crashes while loading.
Will try anyway and let you know.
Thanks!
