PN/CAN Gateway, PROFINET/CANopen Slave | Version 2 | 1/26/2021 35
8 Internal SDO
Some SDOs have functionality in the PN/CAN Gateway that influence the behavior of the gateway or
represent it´s state.
8.1 Start-up behavior SDO 2FFF
This SDO is used to configure the start-up and restart behavior of the PN/CAN Gateway. It can be set
accordingly in the EDS/DCF file. Only subindex 0 is available.

1 = PLC Run is needed for “Operational”
2 = NMT limitation by PLC active
8.2 Status SDO 2FFE
Contains the first two bytes of the PN/CAN Gateway status as shown in the PLC (see chapter 7.2).
