■
Overview
The 3WL / 3VL for SIMATIC PCS 7 library is a block library for the
3WL and 3VL circuit breakers. It allows seamless integration of
the circuit breakers into the PCS 7 process environment.
The 3WL / 3VL for SIMATIC PCS 7 library consists of a driver
block, a diagnostics block, and the faceplates. The blocks in the
SIMATIC S7 supply current, power and energy data to the face-
plates in the user interface of the process control system, gener-
ate signals and ensure connection to the PCS 7 maintenance
system.
Faceplates
Faceplates serve as a user interface for operating and monitor-
ing and make it easy for the circuit breaker to be displayed and
operated as a PCS 7 object.
The 3WL / 3VL for SIMATIC PCS 7 library provides for continual
plant transparency. Critical plant states are recognized quickly
and costs due to outages avoided. System availability is perma-
nently increased.
This transforms the circuit breaker into an integral component of
PCS 7.
The operating systems supported are the same as those for the
SIMATIC PCS 7.
■
Benefits
•
Full integration of the 3WL/3VL circuit breaker into the PCS 7
process control system through PROFIBUS DPV1 using a
certified PCS 7 option
•
Remote switching and monitoring
•
Read-out of maintenance information
•
Automatic information in case of overload, short circuit and
faults
•
Reading out and displaying device data
•
Limit value monitoring by the driver block
•
Resetting of values on the device (min/max values)
■
Application
The 3WL/3VL for SIMATIC PCS 7 library is used in all areas in
which PCS 7 is used. Full integration in PCS 7 means that there
is no need for a special system environment. Predefined mod-
ules and symbols give you the assurance of building on tested
and certified product components.
