Hello, I'm looking for some insight on data usage for Allen bradley IP messages. I have a setup of 4 total Micrologix 1400s. One is the master that polls the rest for data. The master polls once a minute to grab 2 n7 registers from each of the 3 remote PLCs. These are connected together via a vpn setup in a cellular radio from Microhard. The connection works but the data usage is extreme, around 500mb a month. I have never before tried to use Allen bradley IP messages over cell so I am unfamiliar with eh data it uses. I am looking for any help from someone that might have experience using a cell modem vpn and might know if the data usage is correct. Perhaps I should change the setup to use serial instead of ethernet for the communication? Maybe that uses less data? I'm looking for any help on this. Thank you.
