Configuring The Em Dp01 - Siemens Simatic S7 Series System Manual

8.5.1.3

Configuring the EM DP01

Procedure
1. To use the S7-200 SMART EM DP01 PROFIBUS DP module as a DP device, you must
set the station address of the DP port to match the address in the configuration of the
DP master. The station address is set with the rotary switches on the EM DP01.
2. You must power cycle the S7-200 SMART CPU after you have made a switch change in
order for the new DP device address to take effect.
Result
The DP master device exchanges data with each of its DP devices by sending information
from its output area to the DP device's output buffer. The DP device responds to the
message from the DP master by returning an input buffer which the DP master stores in an
input area.
