Appendix
G
P1 – Floor Level Network (FLN)
Appendix G 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.
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.

Understanding P1-FLN
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.
