Thanks for the post. It doesn't sound dumb at all. I've had similar things happen too. I had the program in the processor set both ways with no change in outcome at all. I have not tried checking the box and then burning the eeprom... It seems like that box checking doesn't do squat.
I have started trying to use a memory module for MicroLogix 1100 programming but it will not overwrite the current channel configuration even when the "Memory Module Over-Write Protected" box is not checked. Does anyone know how to get the channel configuration to be overwritten?
Interesting that you should mention ControlLogix. We have gone through that donkey ride about three times here. It always turns out to be more expensive, not to mention that it would cause us to have to move up to a larger enclosure.(we commonly have 34 analog inputs) There is also the battery...
I have received info from Rockwell that indicates what resisters to use for which conversion (simple application of Ohm's Law).
1) A channel of a 1746-NI16V can be configured to function to respond to a current input as follows:
Wanted Select
Current This NI16V
Input...
The answer is actually "Yes." I was quite aware that the card was a current input card and yes you can drive it with a 1-5 volt input and have great results... as long as the device your driving it with can actually drive the 250 ohm input impedence. That's where the problem lies. The...
We commonly use the High density 1746NI16I in our product to measure 4-20 ma analog signals. One of our recent customers has thrown in a set of 1-5 volt signals for us to try to use. Since the input impedence of the card is 250 ohms, wouldn't the fact that the signal is 1-5 volts be transparent...
