4 Control operations can be carried out using the DIGSI
®
4 Tool. Connect a PC to the
PC-interface at front of the device on site, or communicate with the SIPROTEC
®
de-
vice using a modem and the service interface.
DIGSI
®
4 must operate in the On-line mode for this function.
• Select &RQWURO in the Navigation window and double click on %UHDNHU
6ZLWFKHV in the data window.
In the dialog window that follows, all relevant primary control equipment is displayed
in a table with the present status.
• Enter the intended device position in the Scheduled column. Answer the question
with <HV.
The password is requested, the interlocking conditions are checked, and the com-
mand is issued.
CFC Using the graphically supported design tool CFC for logic functions in DIGSI
®
4, infor-
mation can be logically combined. Command outputs can be derived from the output
of logic functions. The link of the output of the CFC functions to the respective device
outputs is determined in the configuration matrix.
Password Only authorized personnel shall perform control operations.
Control operations are
protected by passwords.
Interlocking Command outputs are subject to interlocking checks, which can be configured individ-
ually and graphically using the CFC logic too. Standard interlockings, such as ground
switch closed status indication are already contained in the basic settings of the device
when delivered from the factory.
Command Process-
ing Times
Details about the command output time, checkback indication monitoring time, etc.,
are entered within the framework of the settings.
Event Recording All control operations are recorded in the message list with date and time.
