1.3 PROFIBUS interface
Note
Connector with 180° cable outlet
Use the bus connector with a 180° cable outlet if you want to use the lower PROFIBUS
connector (PB2, slave only) or both PROFIBUS connectors at the same time. You can obtain
these connectors, for example, under the following order numbers:
• 6GK1 500-0FC10
• 6GK1 500-0EA02
PROFIBUS network
The physical link between the PROFIBUS interface and the PROFIBUS network is via a
floating RS-485 interface that is part of the module. Depending on the network configuration,
data rates of 9.6 Kbps up to a maximum of 12 Mbps are possible in the PROFIBUS network.
