7-6 Using Datalinks with All Protocols

Note that certain drives may utilize 32-bit datalinks. In this case, Datalinks
are not supported by the adapter. The adapter will support only 15-bit
Datalink values.
Siemens P1 FLN Datalinks Out: A…D
P1 FLN devices work only with 15-bit integer values; therefore, these
points only show 15-bit values. If an adapter is connected to a host using
32-bit Datalinks, the adapter will be prevented from using Datalinks. The
DPI host determines if 16- or 32-bit Datalink values are used.

points only show 15-bit values. If an adapter is connected to a host using

DPI host determines if 16- or 32-bit Datalink values are used.
!
ATTENTION: Risk of injury or equipment damage exists. On
P1 FLN networks, 16-bit values are truncated to 15-bit values.
Unpredictable operation may result from using non-16-bit drive
parameters with the configurable points. Recognize the data
range limitation of P1 FLN and understand the data value ranges
of each parameter to be accessed over the network. Refer to the
drive user manual for information about drive parameter sizes.
