PLC remote control

[kingkumak]

I need to implement the following application - it needs to be remotely connected via a Internet-11 PLCs*(with Ethernet on board) with one central controller (also with Ethernet on board). Drivers located in different parts of the city (central controller is used to collect data and send commands to PLCs, 11 PLCs connected under central control do not exchange information between themselves). Have you ever had such an application? What devices do you recommend? Both PLCs and industrial remote access devices (routers, etc.).

Whatever you prefer and are comfortable with of industrial equipment. Asking which equipment is "the best" is almost like asking what ice-cream tastes the best; it depends on the person.
