P1 – Floor Level Network (FLN)
This appendix provides information about controlling a PowerFlex 400 drive,
setting its Reference, and accessing its parameters through configurable points
when the P1-FLN protocol is selected. The P1-FLN protocol is a serial
communication protocol used by the Siemens APOGEE® system.
Understanding P1-FLN The P1-FLN master performs read and write commands to certain points, and
the internal P1-FLN protocol firmware transfers/translates the data between
these points and the drive.
When a read or write command occurs to a certain point, data in the point is
refreshed from or transferred to the drive.
The P1-FLN master also performs cyclic polling of all the virtual objects.
P1-FLN Points
A P1-FLN node may contain up to 99 points.

ATTENTION: Risk of equipment damage exists. If a controller is programmed
to write parameter data to Non-Volatile Storage (NVS) frequently, the NVS
will quickly exceed its life cycle and cause the drive to malfunction. Do not
create a program that frequently uses configurable outputs to write
parameter data to NVS unless C107 [Comm Write Mode] is set to option 1.
