Subject: [Emc-users] 7i84 Trouble?
I am working at trying to set up a 7i84 io card on a machine that I am
refitting and I'm having some trouble with it.
The outputs all seem to be working correctly, but I can only seem to get
half of the inputs to work. I have 24v DC to all of the Vin terminals.
The inputs on TB2 seem to all be ok. But the ones on TB3 are not. In Hal,
the 1st 8 inputs (0-7) all read false (no mater what I connect to them, and
the 2nd 8 all read true (8-15) no mater what is connected to them.>
The 7i84 is connected to the SS port on a 7i85S that is connected to a 5i25.
Any ideas what I might have messed up? My best guess is that while I was
wiring up and testing limit switches I may have had a stray loose wire with 24v
touch against some place it shouldn't have. (In hind sight, I probably should
have turned off the 24v while I was working on that.)
Do you have both VFIELDA and VFIELDB connected? sounds like an issue there
