Hi,

I am working on Scada system, we want to use 2 AB plcs in scada system.
One will be 4 KM away on site which will acquire and control analog data and send all this information to another PLC over ethernet optical fibre line at main station. At main station We want to interface it with Foxboro RTU. It works on DNP3 protocol. How can i interface this PLC to RTU using DNP3? previously DNP3 was not there in AB products but In newly luanched Micrologix1400 there is support for DNP3 on channel 0 and 1 but i really dont know how to send data to RTU on DNP3. Can anybody help? Anyone worked on DNp3 before?

Visit the page http://www.prosoft-technology.com/content/view/full/117 there you can find communication gateways that can help you to interconect AB SLC to DNP3.0. About DNP3.0 its a real ghost maybe you can get some training about it, visit http://www.subnetsolutions.com/ and look under services, there is a training schedule with dates and the cities where they provide the training courses.

I hope you can find this useful.

But Micrologix1400 has support for DNP 3. So no need to use Prosoft module for that.

I'm totally unfamiliar with DNP 3 (except as a vague concept) since it is limited to certain equipment used in the utility business, but the DNP 3 interface in the Micrologix 1400 will be using a MSG instruction. So I'd start by getting the latest copy of the Micrologix instruction set manual and looking for the MSG instruction to learn more. In addition, there may or may not be some tech notes on it. Head on over to the Allen Bradley library and look it up in the tech notes database.
