5.4.2 Modbus accessrules
The Modbus should have access rules that indicate which IP addresses have access to the Modbus registers.
Various different access profiles can be created. A Modbus profile has to be linked to each access profile. This
allows it to be determined which application can be associated with which Modbus registers.
