3.4 Software
The UN1020 device supports several operating modes and software features, such as
machine voltage regulator (Auto), field regulator (Manual), measurements monitoring
and others which are described in detail in this section.
There are three different SW function packages defined as BASIC and FULL packages
(and PSS as option only). The table below shows the configurations.
A set of basic software features is enabled by default in each UN1020 product and is
referred to as basic software package. There are optional software features which
extend the UN1020 capabilities and which can be enabled by password.

Once a password code has been acquired from ABB, an optional software feature can
be enabled using the CMT1000 software. A pre-configured device with selected
optional features can also be ordered by means of the product rubric number, and in
this case there is no need for software activation by password. More information
regarding the activation procedure can be found in Chapter 6.4.5 Menu Structure of
CMT1000.
The following sections explain the complete UN1020 software including optional
features. It is clearly mentioned at the beginning of the description if a software feature
is optional or not. The Panel and CMT1000 software are explained in Chapter 6 -
Operation.
After the configuration of the device, the parameters should be stored in the non-
volatile EEPROM memory; otherwise the changes are lost after restarting the device.
The command Save to the EEPROM is used to store parameters in the non-volatile
memory and is explained in Chapter 6 - Operation.
