4.5.3 EtherCAT combined with PROFIBUS
The "Controller-based Automation" system supports further bus systems in the optional mixed
operation in order to make it possible to integrate further field devices.
The EtherCAT bus system can be used in combination with PROFIBUS.
This is reasonable if ...
• not all field devices used are available for the same bus system, or
• a motion bus (EtherCAT) is required in parallel to the PROFIBUS.
EtherCAT (as motion bus) and PROFIBUS (as logic bus)
[4-6] Sample configuration (bus system EtherCAT/PROFIBUS): Controller 3200 C with Lenze field devices
PROFIBUS (Logic)
PROFIBUS is recommendable for the following applications:
• Extension and control of system parts that have already been automated with PROFIBUS and
another control system.
• Use of field devices that are not supported by EtherCAT, CANopen and PROFINET.
• PROFIBUS combined as logic bus with EtherCAT as motion bus.

Note!
Controller c300/p300 do not support PROFIBUS communication.
The PROFIBUS bus system is commonly used for automation solutions.
Because it comes with the widest range of various field devices,
PROFIBUS is occasionally prioritised over more modern bus systems.
Due to the low bandwidth and synchronisation mechanisms, the
controllers only support logic functions when the PROFIBUS bus
system is used.
