SPLat Master to Kaspro Demo

This demonstration program is designed to give you a working example of a SPLat MMi202 communicating with a Kaspro Gemini HMI device. It should provide you with a known, working starting point for your own application. The SPLat is the ModBus Master and the Kaspro is the Slave. With the SPLat as the master it could be controlling other devices via ModBus simultaneously.

We suggest you read through the description below and at the same time familiarize yourself with what the project is doing. Then you can study the code to discover the detailed techniques of what we have done. Once you understand this demonstration it should be easy to modify to suit your own needs.

Note: The Kaspro HMI is a 3rd party product.

What is demonstrated:

 

  • Floating point numbers
  • 16-bit numbers
  • 8-bit numbers
  • Semaphore exchanges both ways
  • ASCII character strings
