Using DeltaV V14 to send a DO signal to the dry contacts of a Rosemount 702DX42 wireless transmitter over a Rosemount 1410S wireless gateway.

I am trying to determine if I can indeed use the dry output contact capability on a 702DX42 Rosemount wireless transmitter (across the 1410S Rosemount Gateway) from  DeltaV to pulse an open command on a remote entrance gate. (24v)

I have heard:

"yes", "no" and " I am not sure".

Anyone?

  I don't have that particular model of 702 to test that it actually works, but all of my research points to it's possible. Here are a few things that you will probably find helpful. The block you would use in DeltaV is a SHDO - Smart HART Discrete Output. It appears the block was added in v13, so it should be available for you in v14. There is a bit of lag with wireless, though it should be possible to get it to just a few seconds assuming that you have a good network design. You'll have to evaluate whether the lag is acceptable for your application.

  In reply to Matt Forbis:

  This is an access gate at the edge of the facility. (In range) absolutely no issue with lag. If I cannot find a “loaner” I may have to beg forgiveness and purchase it quietly.
