Siemens 7SR51 - 2.1 Introduction

Introduction
The device includes protection, supervision, control, data communications and real time clock functions.
The protection, control and supervision functions that can be included in the device are dependent on the
7SR5 device type and it’s hardware configuration. The functionality available to a user is included in the device
Function Template.
Function templates comprise Function Groups (FG) and within each FG there may be a number of Func-
tion Elements (FE).
7SR511 overcurrent devices include a number of FG each containing a number of FE. The maximum function-
ality is tabulated in Figure 2-4 (overcurrent) and Figure 2-5 (directional overcurrent).
7SR5 device function groups and elements can be added or removed only by using the Reydisp Manager 2
(RM2) software configurator tool.
FG and FE that have been included from the RM2 configurator can be enabled/disabled.
