Specifying the active configuration via DP/V1
For DP/V1 the activation status can be accessed via index 6. Index 7 is not supported here
because it was specifically optimized for access via the process data interface.
Access via index 6
Please observe the structure of index 6 when accessing it:
In this example there are 7 connected terminals. Terminals 1, 2, 3, 4, and 7 should be active.
Terminals 5 and 6 are inactive.
The resulting data for object 6 is as follows:
F2

, 00

These 8 data bytes are transmitted via DP/V1 in the following.
Two corresponding examples:
If, as described in this example, the configuration and the available terminals differ,
because, e.g., two terminals are not connected, the bus is read in continuously until it is
matches the configuration. The activation status on index 6 is evaluated automatically.
If the active bus configuration is extended and if previously inactive terminals are attached
at the end, these terminals are first activated via index 6. Next time the bus is started, the
new terminals are integrated into the data traffic. The bus can be started via index 4, bit 0.
Please note that during a restart the terminal output data is reset to its terminal-specific reset
values.

If a new activation status is described via index 6, it only becomes valid when the bus is
restarted.
