Reaction with the default settings
The module parameter Input analogue−value data format"
possesses the default setting VZ + 12 bits right−justified"
(compatible with valve terminal type 03). With this setting the
analogue values will be saved in the input word as follows:
D8
B11 B10 B9 B8
MSB
The channel−specific parameters Lower limit" and Upper
limit" possess the following default settings:
Lower limit = 0
Upper limit = 4095
These correspond to the scaling end values (data range) of
the default data format.
