Dean - Just a thought, I don't know much about the CSMIO, but do you remember the issue we had with proximity switches and the PMDX? The BOB accepted both NPN and PNP switch inputs but was not auto detecting the correct type. We fixed it by adding resistors between the input terminals on the BOB. I doubt it's a similar problem, but just thought i'd throw that suggestion out there incase Charlie is using similar switches.

You having a laugh Si how could I forget that . . . . . . Cost me a nights sleep away from home and the remaining few strands of hair I had left. . Lol

Csmio inputs don't work like the PMDX and doesn't need to detect switch type as your free to use any logic at any voltage upto 30vdc. Your problem was with the PMDX rather than the switch and how it handles PNP logic.

Oh well, it was worth a shot. I guess it's the switches then, unless the length of the wire runs are causing some issues. Might it be worth trying a spare switch separately on shorter wiring into the csmio to test?

It was worth it though to see you dancing around my garden when we got it working though. (yes folks, Dean occasionally does a little dance when he's happy lol).

Thanks for the suggestions anyway


so what do we think the next step is? Run a 3 core wire and try that instead of having them all together?

Try some different switch and if so which ones? Are Any from rs sutable as it would be handy so I could pick one up to try tomorrow.

That's what I suggested earlier but using single core wire. Capacitance acts like a time delay and that's what you are getting.
Better still use a piece of CAT 5 twisted pair, it's imunity to noise is good.

Sorry I must have missed that I will give it a try.

We'll I tried 3 core shielded the full length and no luck I actually had to set the filter higher but still had the same effect. Running out of ideas, perhaps try a short run of cable just long enough to go straight from the box to the switch? Or try a different type of switch
