Architectur SCADA +LCD&keypad
i´m planing small reactor. , need therefore controls. , possibilities check microcontroller. i need control 5 variables, 4 of them feedback and between them 1 of them need high frequency of control (not high mean, air pressure inside reactor of 1 m3, can not go down or reactor "implode", below atmospheric pressure, think there reaction time of half second).
the variables set via scada (http://www.acimut.com/en/monitoriza/monitorizaforarduino.html) , via local display : http://www.adafruit.com/products/772.
the scada need store in database values come this gas sensor http://www.gassensor.com.cn/product_detail_en/typeid/5/id/44.html. gas sensor has answer time of 15 s.
my operative system windows, , not would learn new ones
my plan was:
-arduino uno or due or leonardo micro controller, communicate scada, key pad
-arduino arduino mini 05 without headers dedicated pressure.
questions:
-main controller in loop(sensing , control 4 variables) and have read values set via keypad or via scada new is-value. need use interrupt or what?
-if gas sensor has 15 s answer time, hold controller whole time? ( can avoid reading every 16 seconds, information)
-arduino mini should read value stored in main controller eeprom. therefore should third interrupt?
-how i connect scada arduino uno (i need ethernet? arduino have stay in listening scada, keypad , mini?)... of you, give me advices? do?
