Ok, looks like we don't have a "communications" area in the forum anymore so I guess i'll place this here.
Has anyone had any luck reading/writing long integers (ML/XL). I have a Compact Logix L32E CPU hooked up to Comm 2 on the V570. I can get the regular integers (MI/XI) back and forth just fine, but when I try long integers my message blocks time out.
I suspect either something is wrong in the "mapping tables" that have been provided or that the V570 itself is not mapping the memory properly.
On a side note, I also noticed that for some reason I had to make the array used for storing the incoming V570 data one full element larger than it should need to be. (ie. Its seems as though if I ask the V570 for 8 integers it sends me 9 instead)
Another Side, Side note........
It would be nice to have a sepatate area in the forum dedicated to.....
There is a ton of valuable info on CAN in the old forum.
