Siemens 7SR51 - 4.1 Introduction

Introduction
The device includes configuration 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 termed the 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 Function Groups each of which may contain one or more
Function Elements. The maximum functionality is tabulated in Figure 4-1(overcurrent) and
Figure 4-2(directional overcurrent).
Function groups and elements can be added or removed only by using the Reydisp software configurator tool.
Function groups and function elements that have been included can be Enabled or Disabled using Reydisp
or from the device fascia:
•
Protection and automation function elements, (see 5 Protection and Automation Functions ).
•
Supervision function elements, (see 6 Supervision Functions ).
•
Control function elements, (see 7 Control Functions).
From the device fascia the protection, supervision and control function groups are enabled and disabled in the
Settings > Functions > Function Config menu, (see 4.3 Function Configuration ).
