68 Function Manual, 01/2011, 6SL3097-4AB10-0BP3
The CU305 CAN uses 9-pin Sub D X126 connectors for the connection to the CAN bus
system.
WARNING
Do NOT connect a PROFIBUS cable
Connecting a PROFIBUS cable to CAN connector X126 is highly likely to damage the
CANopen interface of the CU305 beyond repair.
You can use the connectors as inputs or outputs. Unused pins are plated through.
The following baud rates (among others) are supported: 10, 20, 50, 125, 250, 500,
800 kBaud, and 1 Mbaud.
The PC with STARTER is connected to serial interface X22 (RS232).
