Message Mapping

Message Mapping

The communication is based on the continuous data exchange
capability of the ProfiBus standard, where the master sends
continuously the entire slave configuration and reads back the entire
slave status.
Pump parameters that don't need to be modified during operation
are placed in the Parameter buffer and can be set by the user with
the Profibus configuration software ad design-time. Due to different
controller family features (Navigator, ICE and HT families), three
different types of Parameter buffer are provided.
For the real-time data exchange one Input (from slave to master) and
one Output (from master to slave) buffers are provided. All the
needed parameters are mapped inside each buffer. The following
tables reassume the ProfiBus parameter access, related to the
corresponding windows serial protocol (for this protocol please
refers to the controller's manual).
The interface doesn't any scaling operation on the read/written parameters. It
NOTE
acts only as a gateway between the ProfiBus network and the pump's controller
serial interface. As a consequence of this, the scale and the meaning of some
parameters depends directly to the specific model of Turbo Pump controller
connected to the interface. For example the Navigator's family controller
accepts only frequencies expressed in Hz, but the HT family of controller
accepts only frequencies expressed in Krpm. So the user must refer to the
instruction manual of the controller connected to the interface to get the correct
scale of each parameter.

Network Configuration

Some of the operating parameters of the pump are settable during
the "network configuration phase" done with commercial
configuration software (like Siemens com-Profibus).
