A Smart I / O module ine yayo pa-bhodhi microcontrollers. Iwo ma module anotsanangurwa muchitsauko chino Smart I/O modules. Panguva yekutanga ye smart module, iyo module's microcontroller inoshandura iyo
LED yakadzimwa mushure mekunge simba-pa-self-bvunzo rapfuura uye CPU yakatanga module. Iyo LED inovhenekerwa kuratidza I / O kukanganisa.

Iyo CPU inoudzawo iyi module mune chiyero boka chiteshi chega chega chinofanirwa kumhanyisa, pamwe nechero ruzivo rwakakosha (semhando ye thermocouple mune iyo thermocouple module). Panguva yekumhanya, iyo CPU inopota ichitepfenyura "kiyi" kumakadhi ese eI / O, ichivaudza kuti ndeapi mapoka emareti anofanira kuvandudzwa panguva iyoyo.

Kuburikidza neiyi yekutanga / kiyi yekutepfenyura sisitimu, yega yega I / O module inobata yayo yega chiyero-boka kuronga nekushoma CPU kupindira. Aya maI/O mamodule akangwara anewo pa-kadhi pa-line kutadza kuona uye otomatiki calibration/muripo. Imwe neimwe nzira yekupinza ine yayo chaiyo voltage
reference. Kamwe paminiti, usiri kuverenga zvinopinda, iyo-bhodhi microcontroller inoverenga iyi referensi. Iyo microcontroller inobva yashandisa iyi data kuverenga kubva kune voltage referensi yekuona kukanganisa uye otomatiki tembiricha muripo / calibration.

Miganhu yakatemerwa kuverenga kunotarisirwa kana iyo pa-bhodhi microcontroller ichiverenga yega yega voltage referensi. Kana kuverenga kunowanikwa kuri kunze kweiyi miganho, sisitimu inoona kuti chiteshi chekuisa, A/D converter, kana chiteshi chechokwadi-voltage referensi haisi kushanda nemazvo. Kana izvi zvikaitika,
iyo microcontroller inomira iyo chiteshi seine chikanganiso mamiriro. Iyo CPU inozotora chero chiito icho mainjiniya chekushandisa chaakapa muchirongwa chekushandisa.

Iyo yakangwara yekubuda module inotarisisa inobuda voltage kana yazvino yechiteshi chega chega uye inozivisa sisitimu kana kukanganisa kwaonekwa. Imwe neimwe I/O module ine fuse pairi. Iyi fuse inoonekwa uye inogona kuchinjwa kuburikidza nekuchekwa muvhavha yepurasitiki yemodule. Kana iyo fuse yakavhuvhuta, shandura iyo nefuse yemhando imwechete uye saizi.

Mufananidzo 10-3 ibhuroka dhayagiramu yeaviri-chiteshi actuator controller module. Imwe neimwe chiteshi inodzora yekubatanidza kana yakaenzana, hydromechanical kana pneumatic actuator. Imwe neimwe actuator inogona kunge inosvika maviri chinzvimbo mhinduro zvishandiso. Kune akati wandei mavhezheni aripo, uye iyo module chikamu nhamba inoratidza iyo module yakakura yekubuda kugona ikozvino. A MicroNet lowdensity discrete (grey) tambo inofanirwa kushandiswa neiyi module. Usashandise analog (dema) tambo.

Iyi Actuator Driver module inogamuchira ruzivo rwedhijitari kubva kuCPU uye inogadzira mana akaenzana actuator-mutyairi masaini. Aya masaini akaenzana uye huwandu hwawo hwepamusoro 0 kusvika 25 mAdc kana 0 kusvika 200 mAdc.

Mufananidzo 10-5 ibhuroka dhayagiramu yechina-chaneru Actuator Driver module. Iyo sisitimu inonyora zvinobuda kukosha kune mbiri-chiteshi ndangariro kuburikidza neVME-bhazi interface. Iyo microcontroller inoyera kukosha ichishandisa calibration constants yakachengetwa muEEPROM, uye inoronga zvinobuda kuti zviitike panguva yakakodzera. Iyo microcontroller inotarisisa iyo inobuda voltage uye yazvino yechiteshi chega chega uye inozivisa sisitimu yechero chiteshi uye kurodha kukanganisa. Iyo system inogona kudzima yega madhiraivha aripo. Kana kukanganisa kukaonekwa izvo zvinodzivirira module kubva kushanda, neiyo microcontroller kana sisitimu, iyo FAULT LED inovhenekera.
