Please help.
I have two separate projects.
Each project has a CPU 1585 with some inputs and outputs.
However, they are connected via a net switch. Each unit has its own IP address.
For maintenance purposes, is it possible to exchange specific information between the two units to perform a specific task?
Hello,
The most common way to exchange Data via 2 PLCs via a Ethernet Port is to use OPCua.
With the OPCuaFx you can realise realtime data but this requires supported PLCs and AR-Versions.
If you want to imlement a user Spezific Communication you can use AsTCP or AsUDP Library
If you are more into a PLC Redundancy topic you can have a look here.

Thank you, but is it done in the first project, the second project, or both?
here is one example, using OPCUA_any.
Hello,
Most of the Communications need to implement the sender and reciver software. So you will need a modification to both sides.
The only Communication i know which works for B&R PLCs without modification of a AS-Project / PLC is the Build in PVI/INA communication, which is also used for the online communication with Automation Studio. For the PLC there is the AsIMA library.
But normaly PVI is used from Windows systems via PVI Manager or Coustom-Programs using the PVI-API.
