Data strings
In der Slot/Index table some data types, e.g. DS-33 are marked by an asterisk. These are data strings
according to the PROFIBUS-PA specifications part 1, Version 3.0. They contain several elements,
which are addressed by an additional subindex. The following table gives an example.
5.5.7 Scaling of the output data
The on-site display and the digital output are working independently of each other.
On-site display
The on-site display always displayes the main value V0H0 directly from the Transducer Block.
Digital output
For the digital output this value is rescaled in two steps:
L00-FMUx3xxx-05-00-00-en-001
1. In a first step, the main value is mapped to the interval [0;1]. PV_SCALE_MIN and
PV_SCALE_MAX determine the limits of this mapping.
