Set Points for Measured Values
SIPROTEC devices facilitate the setting of limit values for some measured and metered values. If any of these
limit values is reached, exceeded or fallen below during operation, the device issues an alarm which is indicat-
ed in the form of an operational message. This can be allocated to LEDs and/or binary outputs, transferred via
the interfaces and linked in DIGSI CFC. The limit values can be configured via DIGSI CFC and allocated via
the DIGSI device matrix.
Applications
• This monitoring program works with multiple measurement repetitions and a lower priority than the protec-
tion functions. Therefore, it may not pick up if measured values are changed spontaneously in the event of
a fault, before a pickup or tripping of the protection function occurs. This monitoring program is therefore
absolutely unsuitable for blocking protection functions.
2.20.6.1 Setting Notes
Setpoints for Measured Values
Setting is performed in the DIGSI configuration Matrix under Settings, Masking I/O (Configuration Matrix).
Apply the filter "Measured and Metered Values Only" and select the configuration group "Set Points (MV)".
Here you can insert new limit values via the Information Catalog which are subsequently linked to the mea-
sured value to be monitored using CFC.
This view also allows you to change the default settings of the limit values under Properties.
The settings for limit values must be in percent and usually refer to nominal values of the device.
For more details, see the SIPROTEC 4 System Description and the DIGSI CFC Manual.
