7.7.3. Data Exchange Control

Figure 30. I/O data map, Data exchange control enabled
By default Data exchange control is disabled.
When Data exchange control is enabled, the first four bytes of process data on the PROFINET network contain
the data exchange control.
The Data exchange control holds 32 bits.
Each bit in the Data exchange control can be used to enable/disable data exchange for individual nodes on the
subnetwork.
When the bit is 1, it correspond to a node in the state Operational.
When the Data exchange control bit is 0, the node is put in the state Safe-Operational.
The node order in the Data exchange control 32 bit array always matches the Live List.
When the data exchange is enabled for the corresponding node, the control bit is 1.
