To setup Pro-Motion to communicate by SPI:
1 Click the Connect toolbar button.
2 Select SPI, and then click OK.
If SPI communication is successful, an additional set of graphical icons representing your N-Series ION and axis will
be loaded into the Project window.
If communication is not successful, after a few seconds, a Communications Timeout Error dialog box appears. If this
happens, recheck your connections, and retry to establish SPI communications.
2.5 C-Motion Engine User Code
Development
The next few sections will provide information and suggestions to get you started if your application calls for user-
written code to be executed on the N-Series ION’s C-Motion Engine (CME).
Creating, compiling, downloading, and verifying a user-written C-Motion application on a N-Series ION is
accomplished with PMD’s C-Motion Engine development system, described in the
C-Motion Engine Development Tools
Manual . The outcome of such a development sequence is a downloadable .bin file that contains the user application
code and that can be executed by the C-Motion Engine.

Development
Figure 2-6 shows a typical connection architecture for C-Motion Engine user code development with a N-Series ION.
There are three separate communication links:
Pro-Motion Link
The Pro-Motion link connects the PC that holds Pro-Motion, the user source code, and the source code editing and
compiling tools to the N-Series ION that will receive the user code. This link allows the user code, once compiled and
converted into a .bin file format, to be downloaded and eventually executed on the ION’s C-Motion Engine. In
addition this link can be used to monitor the status of the motion system even while the CME-based user application
code is executing. This may be useful, for example, to track the location and status of the controlled axis.
The Pro-Motion link uses PRP (PMD Resource Access Protocol) to communicate with the N-Series ION. For more
information on PRP refer to the
C-Motion/PRP II Programming Reference .
