Process data exchange

Both screens for the process data exchange access the idb_Process_Data data
block (DB11).

Control and status word

The bit commands, which you can partially specify via the digital input module, are
displayed in the 16 bit wide control word.
Figure 4-2
The current state of the SINAMICS G is given via the also 16 bit wide status word.
Manual mode
Using the "Manual mode" button enables activating the manual mode of the block.
Instead of switching to the control signals pending at the block, in this example to
the digital inputs, this mode switches to an internal control word specified via HMI,
for example. Also, an internal value is used instead of the pending setpoint value.
This enables a simple manual/automatic switch-over.
