Hello everyone, I have to put in communication two RPI with Codesys.
The two have to exchange some variables between them.
What is the simplest and cheapest solution?

Thankyou in advance

hi,
cheapest... -> none of them have extra costs every licenses included!

The options are:
Networkvariables (UDP)
ProfinetController - Profinet Device
Modbus TCP / Master - Slave
Ethernet/IP Scanner and Adpater
Netbase Services (see store example plc chat)

Ok i understand but if i want use ModBus TCP i need one Master License like this:

And this license is included or no?!?!
For me i understand is not included, then i need one for master and slave is included.
