Electronic cam shaft
case study
Application description
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
