Maximum data transfer rate and cable length with a PD connecting cable
You can obtain a maximum data transfer rate of 1.5 Mbaud using the PD
connecting cable. The cable length may not exceed 3 meters.
The PD connecting cable should only be connected for an extended period of time
during startup and service.
Data transfer rates over 1.5 MBaud require an active connecting cable for the PD
connection (order number: 6ES7 901-4BD00-0XA0).
