SIMEAS R-PMU
SIMEAS R-PMU is a device that contains triggered fault recorders and continuous recorders as well as an inte-
grated Phasor Measurement Unit (PMU). The PMU measures phasors and makes them available in a database.
This is a high-precision measurement of the vector quantities of voltage and current in terms of amplitude,
phase angle, and time synchronization.
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.
Single command
Single commands (EB) are process outputs which visualize 2 process states (for example, On/Off) at an output.
Single-point indication
Single-point indications (SI) are process indications which visualize 2 process states (for example, On/Off) at
an input.
SIPROTEC
The registered trademark SIPROTEC designates the product family of protection devices and fault recorders.
SIPROTEC 5 device
This object type represents a real SIPROTEC device with all the contained setting values and process data.
SIPROTEC 5 variant
This object type represents a variant of an object of the SIPROTEC device type. The device data of this variant
can differ from the device data of the original object. However, all variants derived from the original object
have its VD addresses. Therefore they always correspond to the same real SIPROTEC device as the original
object. In order to document different working states during parameterization of a SIPROTEC device, you can
use objects of the type SIPROTEC variant, for example.
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.
Slow-Scan Recorder
The Slow-scan recorder is, just like the Fast-scan recorder, a triggered recorder. It records measured values
with the set averaging time. SPS indications can still be recorded. Longer record times are possible using the
Slow-scan recorder.
