Simple Network Management Protocol
The Simple Network Management Protocol (SNMP) is an Internet standard protocol and serves for the admin-
istration of nodes in an IP network.
Simple Network Time Protocol
The Simple Network Time Protocol (SNTP) is a protocol for the synchronization of clocks via the Internet. With
SNTP, client computers can synchronize their clocks via the Internet with a time server.
Simulation data format for single/multiple devices
You can export the simulation-related files of a SIPROTEC 5 device in the SIM format. This new functionality in
DIGSI 5 provides the ability to export the simulation data and simulate all the devices in the DIGSI 5 project for
test and commissioning needs. The simulation is achieved by importing the simulation file into a signal
processing and automation system which will then simulate the device/devices with the process data as in a
real-time system. This feature also ensures the testing of a device for various real-time system conditions.
Single Command
Single commands (SPC - Single Point Control) are process outputs which visualize 2 process states (for
example, On/Off) at an output.
Single-line diagram
A single-line diagram (SLD) is a simplified electric overview of the switchgear. Only 1 phase is shown instead
of all 3 phases of a line. Therefore, the diagram is called single-line.
Single-Line Editor
A Single-Line Editor contains a catalog of topological components to create a single-line diagram. The
customer may use the single-line elements to configure the topological view of his substation.
Single-point indication
Single-point indications (SPS – Single point status) are process indications which visualize 2 process states (for
example, On/Off) at an input.
SIPROTEC 5 device
This object type represents a real SIPROTEC device with all the contained setting values and process data.
SIPROTEC
The registered trademark SIPROTEC designates the product family of protection devices and fault recorders.
Slave device
A slave may only exchange data with a master after its has been requested to do so by this master. SIPROTEC
devices work as slaves. A master computer controls a slave computer. A master computer can also control a
peripheral device.
