IT security with Modbus
Different vendors often provide equipment with Modbus for connection to the DCS system, and at the same time provide ethernet/GSM or others for remote access.
Modbus by itself have no build in security. Are there any IT security measures build in using Modbus RTU on the AC800M COM3 port or on the CI853 ports? Any settings for restrictions, authentification, username/passwords, etc?
