4.1.3 Hardware and software requirements
The following hardware and software items are required in order to communicate with 3WN1/3WS1 circuit-
breakers via PROFIBUS-DP:
Hardware:
••
Circuit-breaker Version MLFB
Fixed-mounted 5 3WN1xxx-xxRxx-xxxx - Z = F01 *
Fixed-mounted 8 3WN1xxx-xxVxx-xxxx - Z = F01 *
Draw-out 5 3WN1xxx-xxRxx-xxxx - Z = F01 *
Draw-out 8 3WN1xxx-xxVxx-xxxx - Z = F01 *
* Circuit-breaker incl. communication-capable overcurrent release and connecting cable
• Overcurrent release version 5 : 3WX31415JC12 or (MLFB for ordering)
• Overcurrent release version 8 : 3WX31416JE12 (MLFB for ordering)
• DP/3WN1, 3WS1 interface module : 3RK1002-0BB00-0AA0
(including circuit-breaker connecting cable)
(ET 200 U used in the example: Power supply : 6ES5 931-8MD11
ET 200 U : 6ES5 318-8MB12
Bus module : 6ES5 700-8MA11
Standard DIN rail : 6ES5 710-8MA11
Digital inputs : 6ES5 431-8MA11
Digital outputs : 6ES5 450-8MD11)
Software:
•• 3.5" diskette with type/GSD file for the software connection of 3WN1/3WS1 to
PROFIBUS-DP (bus configuration). This diskette is supplied with the interface.
• Software for configuring the PROFIBUS-DP bus: "COM-PROFIBUS"
(for SIMATIC S5 as bus master)
Order number: 6ES5 895-6SE12 (Individual license, Catalog ST50 1997)
Manual order number: 6ES5 998-3ES12 (Catalog ST50 1997)
4.2 Functionality and bus connection
The following circuit-breaker output data can be read from 3WN1/3WS1 via PROFIBUS-DP:
Circuit-breaker key data (e.g. circuit-breaker size)
Operational states (e.g. switching state, "Tripped" signals)
Operational data (e.g. actual phase current I
L1
)
... and input data can be written to the circuit-breaker
• Execute switching actions (switch circuit-breaker ON or OFF)
