I am used to programming with Ge Fanuc and older version of RS logix so I wondering if I am programming to recieve an analog wrong, they don't seem to have a lot of help files for just that, Attached is what I have programmed so far, I am just simulating an analog value from a process calibrator fluke741b, into a 1756-IF8 analog card, for a 1756 allen bradley Control Logix
I can read the 4-20ma signal with my other multimeter all through the loop.
I have looked at a allen bradley wiring scematic for the card, and follow it to the t.
The card is calibrated and is set to recieve the 4-20 ma signal
It has a high signal of 20
Low signal of 4
High engineering at 100
Low engineering at 0
I verfied that I am on the right channel.
The value as you can see is -25 whether I simulate 4 ma or 20ma
the address should be right to, it I put the source a of an
equal function block to local1:I.ch3data
