I and my team have converted 4 Raspberry pi’s into PLC’s and these devices are in 4 different locations. The process for one Raspberry pi is coded in ladder logic using codesys and connected to ignition through opc ua. Now i need to connect all these devices which are in different cities or get the tags from all these 4 devices from different cities to a single ignition gateway. Can anyone please help me with this?
Thank you in Advance
