In lookout pocess we have installed NI's ActiveX pumps. We are using Zetron 1700 controller and Zetron 1708 RTU's. In the properties of the ActiveX item I used the Remote URL option to point it to the output of our RTU. There are times that when we click on the pump to turn it on we get a comm failure. Now if I take the same ActiveX item turn off the Remote URL and then go to the connections of the ModBus and bind that output to the ActiveX item there is will work everytime. What could the problem be???
