Hi,

As I understand you already have "scada center"?

You just need device between PLC and "Scada center"? If so, how device with PLC will be connected (via LAN, via RS232 or something else)?

- "the comunications between SCADA and PLC will be made with the protocol Modbus TCP/IP. The interface at the PLC is Modbus TCP. From Teltonika I need sn device with wich I can make the comunications between SCADA and those 30 PLCs."

"The interface at the PLC is Modbus TCP." you mean via ethernet cable?

Seems like basically you just need router with internet connection?

How you connect to PC and read data  directly from PLC? What wires you are using? What software? What parameters you set in that software?
