    Parameterizing 7.2 Protection against tampering 7.2.4 Device access control (IP allowlist) The IP allowlist is a configurable access protection. If the IP allowlist is activated, Modbus TCP write commands are only accepted if the remote station is located in the same subnet. The IP allowlist can be activated on the device in the "Communication"...
