8 Modbus tables
8.1 Numbering of Modbus-Registers
The numbering of the Modbus registers starts with 0 as it is transmitted over the wire. In case your PLC
is using Modicon addressing you have to add 1 to the addresses as provided in the following tables.
8.2 Factory default values
If not otherwise specified in the tables the default value of a parameter is 0.
