2.1.1.2 Setting Notes
Setting the Functional Scope
Your protection device is configured using the DIGSI software. Connect your personal computer either to the
USB port on the device front or to port A or port B on the bottom side of the device depending on the device
version (ordering code). The operation via DIGSI is explained in the SIPROTEC 4 System Description.
The Device Configuration dialog box allows you to adjust your device to the specific system conditions.
Password no. 7 is required (for parameter set) for changing configuration parameters in the device. Without the
password the settings can only be read but not edited and transmitted to the device.
Special Features
Most settings are self-explanatory. The special cases are described in the following.
If you want to use the setting group change function, set address 103 Grp Chge OPTION to Enabled. In this
case, you can select up to four different groups of function parameters between which you can switch quickly
and conveniently during operation. Only one setting group can be used when selecting the option Disabled.
The synchronization function is activated in address 161 25 Function 1 by the setting SYNCHROCHECK or
it is set to Disabled.
Under address 182 74 Trip Ct Supv it can be selected whether the trip-circuit supervision works with two
(2 Binary Inputs) or only one binary input (1 Binary Input), or whether the function is configured
Disabled.
In address 617 ServiProt (CM) you can specify for which purpose port B is used. T103 means that the
device is connected to a control and protection facility via serial port, DIGSI means that you are using the port
to connect DIGSI or you are not using port B (Disabled).
The flexible protection functions can be configured via parameter FLEXIBLE FUNC.. You can create up to 20
flexible functions by setting a checkmark in front of the desired function. If the checkmark of a function is re-
moved, all settings and configurations made previously will be lost. After re-selecting the function, all settings
and configurations are in default setting. Setting of the flexible function is done in DIGSI under„ Parameters“,
„Additional Functions“ and „Settings“. The configuration is done, as usual, under „Parameters“ and „Configura-
tion“.
