I swapped out a 1771 ofe1 with a 1771 ofe2/b. Got the config in and the btw/btr rslogix created.
I am having an issue with the scaling registers. 4095 max keeps pushing 16533 to the data file registers of the btw. Conversely, if I change the value in the data file to 16533 it pushes 1655 to the max scale of that channel in the i/o config.
Any idea where/how this is happening? It is set for BCD data type. I tried two's complement binary option without much change.
This is what I believe to be causing my issues with output current not stepping in a linear fashion. I have to be around half of the scale to get 20mA to drop. It seems a little better on low end but still doesn't oscillate with changing values in btw data file registers.
Ladder 2 rungs 255/256 in attachment.
Any ideas/insight would be appreciated.
Thanks!,
Ben
