Setting the toggle bit:
The flag NA has to be set before the application is started. In case it is not set, the
flags have to be read out until this flag has been set to 1.
The flag NA indicates that the master is in normal operation mode.
Normal operation mode is necessary to run the application safely.
If a command of the command interface is used via PROFIBUS DP V1, it is not
necessary to use the toggle bit.
The flag NA indicates that the master is in the normal operating mode which is nec-
essary for the application to run safely.
