Manual Doc. No.: C.2931.21 / Rev. 1.0
CANopen-PN/2
3 Start-Up
After switching on the supply voltage, the CANopen-PN/2 starts automatically. During start up the
‘R’ LED (CANopen Status) turns on. When the device is started successfully ‘PWR’ LED (Power)
turns on and ‘R’ (CANopen Status) turns off again. This process takes about 10s.
The gateway is now ready to be configured by the PROFINET controller.
When the gateway has established a connection to the PROFINET network, the ‘CON’ LED
(PROFINET Connect) turns ON. When the CAN bus is not faulty, the ‘R’ LED (CANopen Status)
turns on, too.
After the PROFINET controller changes to state RUN, the data exchange is started automatically.
When the PLC changes to the state STOP, no more CAN frames are sent.
