Dear Experts,
I want to learn how to communicate to a ModbusTCP slave device using a ModbusTCP master (SCADA) that are not on the same network over internet. The slave may have a GSM/GPRS modem or 3G dongle to connect to internet. One possible way I know of is using VPN, but I don't know how to exactly do it.
Can anyone show me the procedure or pointers on how to communicate to ModbusTCP Slave using ModbusTCP master over VPN. A big question to my mind is, how to setup VPN for the ModbusTCP slave? or how to find out the (dynamic) IP of the slave?
Thanks in Advance. This will help me in learning such things.
