Using Datalinks with
Siemens P1 FLN This section presents information about using Datalinks with Siemens P1
FLN networks. For information about using Datalinks for Modbus networks
or Metasys N2 networks, refer to the
Using Datalinks with Modbus or
Using Datalinks with Metasys N2 sections in this chapter.
DLNK A1 OUT to DLNK D2 OUT contain the Datalink Out A1 to D2
parameters from the drive. DLNK A1 IN to DLNK D2 IN contain the
Datalink In A1 to D2 parameter values to the drive.
For example, a PowerFlex 70 or 700 drive enabling Datalink A for the
adapter and configuring drive Parameter 310 - [Data Out A1] to “1” will
provide drive Parameter 1 - [Output Frequency] at the DLNK A1 OUT
point. Configuring Parameter 300 - [Data In A1] to “140” in the drive will
transfer the value of the DLNK A1 IN point value to drive Parameter 140 -
[Accel Time 1] when accessed.
