Digital input, packed data type
If the datatype is P (= Packed), the SPA message format FirstCh/LastCh and
FirstDno/LastDno is used. The datatype numbering of Ch and Dno has to be
consecutive when the data type is packed.
The packed data type allows the gateway to read multiple binary data by using one
SPA command:
• Enabling faster updating of data, which is always polled and not updated by
events.
• Consuming less bytes on the profibus side.
This data is packed in 2 bytes in the profibus side. The first data is in bit number 0
and the second in bit number 1 and so forth.
Analog output
When you have opened a template with an analog output into the main window, you

Fig. 5.4.8.4.-1. The fields that you cannot configure are dimmed.
3. To save the new settings, click OK. To cancel, click Cancel to discard all
changes.
