ET 200S in the PROFIBUS Network
Examples for the Connection of the Programming Device/OP on the ET 200S
The programming device/OP is connected to the PROFIBUS-DP interface of
the DP master, but can be connected just as well to any other station in the DP
network, including the ET 200S.
Figure 3-2
The programming device is connected to the ET 200S on a stand-alone basis
for commissioning (you don't add the ET 200S to the PROFIBUS network until
later).
Note: A special setting must be made in STEP 7 for the stand-alone operation
of the ET 200S with the IM 151/CPU if there is no active PROFIBUS node on
the bus except the programming device (see Section 3.4).
Figure 3-3
The programming device can also be a direct DP node, although a spur line
(e.g. programming device connecting cable) is not permissible with a
transmission rate of 12 Mbps.
