8.1 Serial compatibility with URDR0001
In existing plants where it is necessary to replace an URDR0001 it is possible to install a new URDR001A
enabling the Modbus register’s compatibility.
To enable the Modbus register’s compatibility with the URDR0001, simply enter the password 0243.
To return again to the URDR001A Modbus mapping, enter the password 0244.
The new register map is the following:
