Acquisition and control of internal and external data (DAQ)
Different types of logical and physical sources that have data access utilities or accessible through simple and specialized network protocols. This is accomplished by writing a data acquisition procedure of the user protocol in the user programming language. Most known protocols implementing on the user protocols:
  • Industrial devices library
    • Industrial automation: Elemer TM510x, EDWARDS TURBOMOLECULAR PUMPS (SCU750), Sycon Multi Drop Protocol, Power supply for turbomolecular pumps (TMP-xx03), Temperature measurement IT-3, IVE-452HS-02, OPTRIS CT/CTL, CTR 100-101, IEC-60870-104, Shark Slave Communication Protocol, DCON (example), OWEN (example).
    • Counters of the resources: Heat counter computer VKT7, Mercury 200, Mercury 230, Nik2303I.
  • Low level sensors and chips library
    • I2C: PCF8591, PCF8574, BMP180, BME280, DS3231, AT24CXX;
    • 1Wire Chips by the adapters DS9097 and DS9097U: DS1820, DS1820/DS18S20/DS1920, DS1822, DS2413, DS2408, DS2450, DS2438;
    • Low level devices by GPIO: DHT11,22 (DHT), 1602A(HD44780).
