3. Description of Function
The DSR Terminal user Interface is presented as shown in figure 15 and permits programming and
monitoring from 1 to 32 slave units connected through serial RS485 or a single unit connected through
RS232. The functions available are shown in table 20.
The DSR Terminal user interface is divided into 6 areas with different functions.
Transmit : Handles data transmitted towards slave units (DSR/DER1)
Receive : Displays a single datum requested from slave units (DSR/DER1)
Cyclic Read : Displays, almost in real time, four pieces of information memorised on consecutive
locations in the slave unit (DSR/DER1)
STATUS : Displays registries from 36 to 39 (measured voltage, measured frequency, active alarm flags
and configurations)
ALARMS : Displays active alarms (alarms and individual word alarm flags are shown in table 13).
COMMUNICATION : Displays the status of communication
The Configuration Menu
The Configuration Menu is indicated in figure 16; it permits setting of configuration flags of the DSR/
DER1 regulator (parameter P[10]).
File Menu
The
File Menu presents the single option of Exit, to close the DSR/DER1 Terminal user interface.
Up/Dw Menu
The
Up/Dw Menu is used to load and unload settings files to and from the regulator (which have the
extension .dat). The list of parameters is shown in table 6.
There are three possible options:
1. Upload Data The “Upload” window opens
•
The key Open allows selection of files with the .dat or .set extension, which must be loaded.
•
The Upload key unloads the parameters of settings files into the DSR/DER1 regulator; if the file has
been opened with the .dat extension, all of the parameters are updated, if the file has been opened
with the .set extension, only the parameters from 10 to 30 are updated, leaving those from 0 to 9
unaltered.
•
The key Done closes the Upload window
2. Download Data: The “DownLoad” window opens
•
The DownLoad key transfers the settings files to the personal computer.
•
The key SaveAll permits the operator to save the entire settings file (from 0 to 30) with the .dat
extension.
•
The key SaveSettings allows you to save the file with customised data (parameters from 10 to 30)
with the .set extension.
•
The key Done closes the DownLoad window.
3. DownLoad Alarm: The “DownLoad Alarm” window opens
•
The key DownLoad transfers the list of memorised alarms to the personal computer, as many times
as the alarms intervened and, for each of them, the duration of the last event and the overall duration.
•
The key Save allows the operator to save the alarms file with the .alr extension.
•
The key Done closes the DownLoad Alarm window.
