Neuron C (NV, CP, FB, Events, Msgs) Ø Network Variables (Δήλωση στη Neuron C και Firmware) Δημιουργεί το ένα μέρος του Lonworks Device Interface. Standard Network Variable Types = SNVT’s Πχ. network output SNVT_lev_disc nvo_switch; Ø Configuration Properties (Device Behavior Customization) Δημιουργεί το άλλο μέρος του Lonworks Device Interface. Standard Configuration Property Types = SCPT’s Μορφοποιούνται από κάποιο Network Tool (πχ. Lon. Maker) Ø Functional Blocks (Network Variables + Configuration Properties) defined by Functional Profiles Ø Event driven scheduling system Πχ. // Event driven Task when (io_changes(Switch 2) ) { nvo_switch_state = input_value; } ØLower level messaging service Πχ. // Message Task when (msg_arrives(10) ) { ………… }
Neuron C (Timer, I/O Object) Ø Timer (Δηλώνονται στη Neuron C σαν μεταβλητές και ελέγχονται από το Firmware) Πχ. stimer 1 = 5; // start timer 1 with value 5 seconds when (timer_expires(timer 1) ) { ………… } ØI/O Objects (Δήλωση στη Neuron C και Firmware) Είναι standardized I/O Device Drivers για το Neuron chip. Πχ. IO_4 input bit Switch 1; IO_1 output bit relay 1; IO_6 output bit io_nw 1_cs = CS_OFF; IO_7 output bit io_nw 2_cs = CS_OFF; IO_8 neurowire master select(IO_0) kbaud(20) io_nw 1; IO_8 neurowire master select(IO_7) kbaud(20) io_nw 2;
I/O OBJECTS
Direct I/O Objects (logic at pins) Timer / Counter I/O Objects
Serial I/O Objects (I or O) Serial I/O Objects Parallel I/O Objects
Neuron Chip I/O Objects
EVENTS “WHEN”
Προκαθορισμένα (Predefined) Events Συστήματος / Scheduler Πχ. when (timer_expires(timer 1) ) { ………… } Events από Ι/Ο Πχ. when (io_changes(Switch 2) ) { ………… }
Προκαθορισμένα (Predefined) Events από NV Πχ. when (nv_update_occurs(nvi_relay_state) ) { io_out(relay 1, nvi_relay_state); } Events από Messages Πχ. when (msg_arrives(10) ) { ………… }
User - Defined Events Κάθε Neuron C έκφραση η οποία έχει Boolean αποτέλεσμα Δηλαδή 1 ή 0 (True or False) Πχ. when ((timer_expires(timer 1) ) && (flag == TRUE)) // Task to execute { ………… }
