Field devices Generic term for all devices assigned to the field level: Protection devices, combina-
tion devices, bay controllers.
Bay controllers Bay controllers are devices with control and monitoring functions without protective
functions.
Chatter blocking A rapidly intermittent input (for example, due to a relay contact fault) is switched off
after a configurable monitoring time and can thus not generate any further signal
changes. The function prevents overloading of the system when a fault arises.
FMS communica-
tion branch Within an FMS communication branch the users communicate on the basis of the
PROFIBUS FMS protocol via a PROFIBUS FMS network.
General interroga-
tion (GI) During the system start-up the state of all the process inputs, of the status and of the
fault image is sampled. This information is used to update the system-end process
image. The current process state can also be sampled after a data loss by means of
a GI.
Device container In the Component View, all SIPROTEC 4 devices are assigned to an object of type
Device container. This object is a special object of DIGSI Manager. However, since
there is no component view in DIGSI Manager, this object only becomes visible in con-
junction with STEP 7.
GPS Global Positioning System. Satellites with atomic clocks on board orbit the earth twice
a day in different parts in approx. 20,000 km. They transmit signals which also contain
the GPS universal time. The GPS receiver determines its own position from the
signals received. From its position it can derive the running time of a satellite and thus
correct the transmitted GPS universal time.
