Application description

Cam shaft Electronic camshaft RS-97 is connected through synchronous serial interface to encoder and communicates through INTERBUS S with programmable logic vontrol (PLC). Besides function of alon camshaft, RS-97 is able read from PLC failure bits for text terminal OP-96 and handle programmed error messages.

Firmware RS-97 functions

  • communication with encoder through SSI
  • scales of information about position in 360 steps to 1 evolve, comparison of information about position stored in RS-97 with information form encoder
  • 32 cam trajectories with following types
    • Start/Stop - maximum 5 start-stop at evolve
    • Path/Time - one start - stop at evolve in defined time
    • Dynamic - similar to Path/Time but with allowing to speed rotation
  • Save and data handle about trajectories for maximum 100 programs (1 program includes data about 32 cam trajectories and is defined for pressing one type of pressing)
  • program development for RS-97

SAE - Automation provided not only complete implmentation of firmware RS-97 but also set-up software for PC, which provides

  • programs creating for RS-97 off-line
  • semigraphic displaing of created programs
  • on-line developed programs uploading
  • off-line developed programs downloading
  • creating and printing reports
  • management and programs back-up in one list

On the simplest application - "Hello World", which is used by easiest description of many software development environments and programming languages, we explain options and basic principles of creating applications in the OpcDbGateway development environment , in which comprehensive database and communication applications for industry, energy and other domains can be developed without deep knowledge of modern programming languages. Those who have programming skills can add own program modules to the OpcDbGateway. See the article OpcDbGateway - Hello World .
