Glossary
Online
If there is a communication connection between a PC program (for example, configuration program) and a
runtime application (for example, a PC application), the PC program is online. The PC program executes in
Online mode.
Order Configurator
One or more appropriate modules are suggested in the order configurator corresponding to the desired
protocol on a module. You will also find the available standard variants in the order configurator.
OSM
See Optical Switch Module.
Output data/output direction
Data is sent from the protocol master to the protocol slave.
Output Indication
Indications can be information provided by the device on events and states. The events and states are
provided via binary outputs, for example, startup of the processor system (event) or fault in a device function
(state). These are designated as output indications.
Parameterization
Comprehensive term for all setting work on the device. You can parameterize the protection functions with
DIGSI 5 or sometimes also directly on the device.
Parameter set
The parameter set is the entirety of all parameters that can be set for a SIPROTEC device.
Participant
In an inter-device communication group, up to 16 SIPROTEC devices suitable for this can communicate with
one another. The individually involved devices are referred to as participants.
Participant Address
A participant address consists of the name of the participant, the international dialing code, the local dialing
code and the participant-specific telephone number.
PDC
See Phasor-Data Concentrator
Phasor-Data Concentrator
PDC. This component collects the information of the PMU devices and makes it available to both other compo-
nents.
Phasor Measurement Unit
The Phasor Measurement Unit (PMU) is a measuring device for power systems. It is capable of taking phasor
measurements of voltages and currents in large, widely distributed networks.
