2.17.6 Set Points for Measured Values
SIPROTEC devices facilitate the setting of limit values for any measured or metered values. Should any of
these setpoints be reached, exceeded or undershot during operation, the device issues a warning which is in-
dicated in the form of an operational message. This message can be configured to LEDs and/or binary outputs,
transferred via the ports and interconnected in DIGSI CFC. In addition you can use DIGSI CFC to configure set
points for further measured and metered values and allocate these via the DIGSI device matrix. In contrast to
the actual protection functions the limit value monitoring function operates in the background; therefore it may
not pick up if measured values are changed spontaneously in the event of a fault and if protection functions are
picked up. As a message is only issued upon multiple exceeding of the limit values, such limit value monitoring
does not react as fast as the trip signals of protection functions.
Applications
• This monitoring program works with multiple measurement repetitions and lower priority than the protection
functions. For that reason, in the event of a fault it may not respond to fast measured value changes before
protection functions are started and tripped. This monitoring program is not suitable for blocking protection
functions.
