Data Exchange Plc5/40 to Controllogix556 with controlnet

3 posts in this topic

Hi, everybody

I began to study Allen Bradley controllers. And faced with such a question. From the PLC 5/40 controller data is transmitted to the Control logix 5561 controller via the Controlnet protocol. I know that it is possible to transfer data through the MSG instruction. But in the controller program, I did not meet the instruction MSG, but the data is somehow transmitted. There is another way to transfer data? Is it possible to organize a transfer through RSNetworx? If so, where can I get information about this? thanks

It is quite possible RSNetworx for ControlNet has a scheduled transfer from one PLC to the Other.

You'll need to go online with the ControlNet Scanner and RSNetwox to determine this.

Been 15 years since I've had to do that so pardon I'm very rusty and probably not the best to guide you.
