5.3 Profibus DP protocol
1. Setpoint and material number:
2. Other values:
The controller requires at least 100 ms to accept. It can be accepted by waiting
this period or also by reading back current values. Reading back is done by setting
the corresponding read-ID.

The fieldbus is always the sole determinant source when the ID in the telegram
assigned to the value is transmitted from the master to the controller. Any
values from other sources are then overwritten in the next fieldbus cycle.
If you want to use the fieldbus to change the value, set the desired value in the
fieldbus protocol and then transmit it to the controller together with its ID. To
allow other sources to specify, the IDs for setpoint or material number have to
be set to zero or the ID on of a different value in the fieldbus telegram. That
means that the specification IDs determine which source has priority.
The controller accepts the manual tare of the scale displayed and the data
PLS-AIN-1 - PLS-AIN-4 after changing the corresponding values.
