Acquisition interpreters can reference an acquisition of the data pool and forward the data after manipulation.
The following settings can be made:
Acquisition
Acquisition
Selection of the acquisition used from the data pool.
Modify
Bitmask
In this field a value can be entered with which the display value is masked, provided it is not of the type floating point. This means that the value of the channel is ANDed with the binary value of the mask. This helps you, for example, to observe individual bits of a status byte.
Offset
A free offset can be added to the function value of the channel in the offset field.
Scalefactor
The display value of a channel can be changed with the scale factor.
Unit
This property enables the physical unit to be configured individually for the X-acquisition and the Y-acquisition of the channel. This can be done with the aid of the "Unit Wizard", which can be opened using the button on the right in the field. A further option is to define the units beforehand as attributes in the PLC code. These are then read out directly and entered in the Unit field. Detailed information on the units and their configuration options can be taken from the chapter .
