3.4 Fieldbus interface
With CMMS-ST, different field buses can be used. By default, the CAN bus is permanently
integrated in the controller with the CMMS-ST. Optionally, the PROFIBUS or DeviceNet can
be used via plug-in modules. But only one field bus can be active at any given time.
For all field buses, the Festo Profile for Handling and Positioning (FHPP) has been
implemented as the communication protocol. Additionally, for the CAN bus, the
communication protocol based on the CANopen profile in accordance with the CiA Draft
Standard DS301 and the drive profile in accordance with the CiA Draft Standard Proposal
DSP402 have been implemented.
Independent of the field bus, a factor group can be used so that application data can be
transferred into user-specific units.
Required I/O connection for field bus control
The connection plan shows the switch position in the active operating state.
*) The limit switches are set by default to opener (configuration over FCT)
3.4.1 FHPP
FHPP makes it possible to achieve a uniform control concept regardless of the field bus
used. The user therefore no longer be concerned with the specific characteristics of the
respective buses or controllers (PLC), but receives a preparameterised profile in order to
place his drive into operation in the shortest possible time and control it.
Among the operation types, FHPP distinguishes between record selection and direct
operation.
