Step 5:
Connect the 24 V DC voltage supply (DIN 19240) to the interface module: The interface module is
fitted with a 4-pole screw terminal to facilitate the through connection of the 24 V supply.
Note: In order to switch the 3WN6 circuit-breaker ON and OFF via PROFIBUS-DP, a 24 V DC
supply must be connected to auxiliary plug X400.6 (cf. Fig. 5, page 32 and Fig. 6, page 32 in Step
2). For all other functions (monitoring, remote parameterization), the 24 V DC supply to the interface
module is sufficient for supplying the communication electronics of the circuit-breaker.
Step 6: Bus configuration
If SIMATIC S5 is the bus master, the bus can be configured quickly and easily using either a PC or
a SIMATIC programming device (PG) in conjunction with the COM-PROFIBUS or COM 5431
programs. In the case of other bus masters, the appropriate devices and/or supplier-specific tools
must be used.
The object of bus configuration is to define the 3WN6 device data, the 3WN6 bus address and the
3WN6 data area (I/O area) in the bus master. The 3WN6 device data can be read into the master in
the form of type or GSD files. The following list outlines which file is required for which master:

Step 7:
The bus address defined for 3WN6 in Step 6 can be set on the front panel of the DP/3WN6
interface module by means of 2 rotary switches (range 00 - 99). The rotary switch on the left (x10)
sets the tens and the rotary switch on the right (x1) sets the units for the address.
The baud rate cannot be set on the interface. It is automatically adjusted in line with the baud rate of
the bus master (e.g. SIMATIC S5).
Note: The communication connection to the circuit-breaker is automatically set up when the
DP/3WN6 interface module is connected to the voltage supply. This power supply also activates the
circuit-breaker overcurrent release (in the case of draw-out circuit-breakers in the connected and
test positions). This permits the functionality of the slave "3WN6 circuit-breaker" to be checked and
guaranteed. In the case of draw-out circuit-breakers in the disconnected position, the circuit-breaker
state is detected using a separate microswitch (circuit-breaker detection signaling switch S20) in the
guide frame. This is then signaled to the operational DP/3WN6 interface (see also DP/3WN6 user
guide) in the form of a diagnostic message. Communication with the 3WN6 via the bus is not
possible in this case. The presence of the circuit-breaker is merely checked.

The type and GSD files are also available under the following modem number: 0911-737972

The maximum possible baud rate corresponds to the maximum baud rate of the slowest field device.
