Configuring the EM DP01 I/O
You can configure the EM DP01 I/O by using pre-configured or universal module I/O
configuration selections. The EM DP01 configuration allows for two slots so that you can
have more than 128 bytes of data transferred between the DP master and the
S7-200 SMART CPU. This makes it possible for you to configure the maximum of 244 bytes
that PROFIBUS allows. Two possible I/O configuration combinations are shown in the
following examples.
32 Bytes In/Out and 8 Bytes In/Out configuration
In this example, slot one contains the "32 Bytes In/Out" pre-configured I/O selection, and slot
two contains the "8 Bytes In/Out" pre-configured I/O selection.
In the "Properties"", "General" tab area navigation, click on "Device-specific parameters" to
display the "I/O Offset in the V memory" field. Here, you can assign the starting address of
the section of V memory reserved for this operation.
