Yes it is possible. You can add the function SetValue when a Tag in one PLC changes value. Open the properties of the tag and find the Event ChangeValue. Then add the function SetValue. Lat the target be the other Tag in the other PLC, and the value the Tag in the 1st PLC. However, only use this for non-critical dataexchange. Shutting down the PC or panel will halt the datexchange. For critical data exchange I recommend the Profibus via for example a Profibus DP/DP coupler.
