Thank you in advance.

 

I have a K t/c into the - and + of my V200-18-E3XB snap in. I changed my jumpers as per included sheet.  I hardware configured it to MB1. After download/reset, and going online (glasses) and I look at MB1 it is still 0 value.  I also tried a different t/c to no avail. Do I need anything attached to CM or ACM? it is only a 2 wire t/c.

 

Sorry I am really green to this.

Did you run +24V and 0V to V2?  It's not obvious in the documentation that you have to power the module for any input to work.

Joe,

 

I figured it would be something simple that would make me hang my head  

 

Thank you Joe,

Don't hang your head!  As I said, it's not obvious.  I am so brilliant on so many things Unitronics because I've made so many mistakes working with the product for 15 years, including the one you experienced.  Trudge on to project success!

+1 to what Joe has said, although I'm not so brilliant!!  (Is there an emoticon for "grovel before master"?!!)

 

I well remember scratching my head years ago on the very same issue, .

 

At the time, I thought it was just me being stupid, but given that it looks like other people seem to be caught on this one, perhaps the literature should make it a bit more obvious.

 

cheers,
