Set-up. Main plant PLC talks to 5 remote PLC over DSL line. at remote plants, each have cellular modems to connect to the internet. they all have cisco firewall with VPN connection established.
GE 90-30PLC which are using COMM_REQ SRTP channel commands. and these are communicating over ethernet through cellular modems. the data plan on the cellular modem has a limit of 5GB only.
The PLC have been communicating GOOD with the only exception that it is using a lot of DATA (maybe around 9-20 Mb/hr which puts it close to 5 gb/month or more.
how to slow it down.?
