Module ya Smart I/O ili ndi ma microcontrollers ake pa board. Ma module omwe afotokozedwa m'mutu uno ndi ma module a Smart I/O. Poyambitsa gawo lanzeru, microcontroller ya module imatembenuza
Kutuluka kwa LED pambuyo podziyesa-yekha kwadutsa ndipo CPU yayambitsa gawoli. LED imawunikiridwa kuti iwonetse vuto la I/O.

CPU imauzanso gawoli momwe gulu lililonse liyenera kuyendetsa, komanso chidziwitso chilichonse chapadera (monga mtundu wa thermocouple pankhani ya gawo la thermocouple). Panthawi yothamanga, CPU ndiye nthawi ndi nthawi imawulutsa "kiyi" kumakhadi onse a I/O, kuwauza magulu omwe akuyenera kusinthidwa panthawiyo.

Kupyolera mu makina oyambira / ofunikira, gawo lililonse la I/O limayang'anira ndondomeko yake yamagulu ndi kulowererapo kochepa kwa CPU. Ma module anzeru a I/O awa alinso ndi kuzindikira zolakwika pamakhadi pa intaneti ndikuwongolera / kubweza. Njira iliyonse yolowera ili ndi voteji yake yolondola
umboni. Kamodzi pamphindi, osawerenga zolowetsa, wowongolera pa bolodi amawerenga izi. Woyang'anira ma microcontroller amagwiritsa ntchito izi zomwe zimawerengedwa kuchokera pa voteji kuti zizindikire zolakwika komanso kubweza / kuwongolera kutentha.

Malire akhazikitsidwa pazowerengera zomwe zikuyembekezeredwa pomwe microcontroller yomwe ili pa board ikuwerenga ma voliyumu aliwonse. Ngati zowerengera zomwe zapezedwa zili kunja kwa malire awa, makinawo amatsimikizira kuti njira yolowera, chosinthira cha A/D, kapena tchanelo cholondola chamagetsi sichikuyenda bwino. Izi zikachitika,
microcontroller imayimitsa njirayo ngati ili ndi vuto. CPU idzachita chilichonse chomwe wopanga mapulogalamuwa apereka mu pulogalamuyo.

Module yotulutsa mwanzeru imayang'anira mphamvu yotulutsa kapena yapano ya tchanelo chilichonse ndikudziwitsa dongosolo ngati cholakwika chazindikirika. Module iliyonse ya I/O ili ndi fusesi pamenepo. Fuse iyi ikuwoneka ndipo ikhoza kusinthidwa kudzera mu chodulidwa mu chivundikiro cha pulasitiki cha module. Ngati fuyuzi iwombedwa, m'malo mwake ndi fusesi yamtundu womwewo ndi kukula kwake.

Chithunzi 10-3 ndi chithunzi cha block cha module yowongolera njira ziwiri. Njira iliyonse imayang'anira chophatikiza kapena chofananira, hydromechanical kapena pneumatic actuator. Woyendetsa aliyense akhoza kukhala ndi zida ziwiri zoyankha. Pali mitundu ingapo yomwe ilipo, ndipo gawo la gawo la gawo likuwonetsa kuthekera kokwanira kwa module. Chingwe cha MicroNet lowdensity discrete (imvi) chiyenera kugwiritsidwa ntchito ndi gawoli. Osagwiritsa ntchito chingwe cha analogi (chakuda).

Module iyi ya Actuator Driver imalandira zidziwitso za digito kuchokera ku CPU ndikupanga ma siginecha anayi ofananirako oyendetsa. Zizindikirozi ndizofanana ndipo kuchuluka kwake ndi 0 mpaka 25 mAdc kapena 0 mpaka 200 mAdc.

Chithunzi 10-5 ndi chithunzi cha block cha module ya Actuator Driver ya njira zinayi. Dongosolo limalemba zotuluka pamakumbukidwe apawiri-doko kudzera pa mawonekedwe a basi ya VME. The microcontroller amayesa miyeso pogwiritsa ntchito ma calibration constants osungidwa mu EEPROM, ndikukonzekera zotuluka kuti zichitike panthawi yoyenera. The microcontroller imayang'anira mphamvu zotulutsa ndi zomwe zikuchitika panjira iliyonse ndikudziwitsa dongosolo la njira iliyonse ndi zolakwika. Dongosololi limatha kuletsa aliyense payekhapayekha madalaivala omwe alipo. Ngati cholakwika chizindikirika chomwe chimalepheretsa gawoli kugwira ntchito, mwina ndi microcontroller kapena dongosolo, FAULT LED idzawunikira.
