The Pd/Op Accesses The Et 200S Via The Dp Interface In The Dp Master; The Pd Directly Accesses The Et 200S - Siemens SIMATIC ET 200S Manual

Examples for the connection of the PD/OP on the ET 200S
S The PD/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 4-3
S The PD is directly connected to the ET 200S (you don't add the ET 200S to the
PROFIBUS network until later).
Note: Depending on the DP interface (active/passive), a special setting is
required in STEP 7 (see Section 4.4).
Figure 4-4
S The PD can also be a direct DP node, although a spur line (e.g. PD connecting
cable) is not permissible with a transmission rate greater than 1.5 Mbaud. This
requires an active spur line.
