Kaadhka ilaalinta mishiinada MPC4 waa unugga dhexe ee nidaamka ilaalinta mishiinada taxanaha ah ee VM600 (MPS). Kaadhkan aadka u kala duwan waxa uu awood u leeyahay in uu cabbiro oo uu la socdo ilaa afar qalab oo signal-dhaqaale ah iyo ilaa laba xawaarahooda isku mar isku mar ah.

Gelitaanka calaamadaha firfircooni waa kuwo si buuxda loo baran karo oo waxay aqbali karaan calaamadaha ka tarjumaya dardargelinta, xawaaraha iyo barokaca (u dhawaanshaha), iyo kuwo kale. Habbaynta kanaalka badan ee dusha sare waxa ay u ogolaataa cabbiraadda cabbirro kala duwan oo jireed, oo ay ku jiraan qaraabo iyo gariir dhammaystiran, Smax, eccentricity, booska riixista, balaadhinta guryaha oo dhammaystiran iyo kala duwanaansho, barokac iyo cadaadis firfircoon.

Habaynta dhijitaalka ah waxaa ka mid ah shaandhaynta dhijitaalka ah, is dhexgalka ama kala soocida (haddii loo baahdo), hagaajinta (RMS, qiimaha celceliska, ugu sarreysa dhabta ah ama ugu sarreysa-u-sare ee runta ah), nidaamka raadraaca (ballaaran iyo wejiga) iyo cabbirka farqiga dareenka-bartilmaameedka.

Xawaaraha (tachometer) ee wax-soo-gelinta waxay aqbalaan calaamadaha dareemayaasha xawaaraha kala duwan, oo ay ku jiraan nidaamyada ku saleysan baaritaanka u dhow, dareemayaasha garaaca garaaca magnetic ama calaamadaha TTL. Saamiyada tachometer-ka jajaban ayaa sidoo kale la taageerayaa.

Qaabeynta waxaa lagu muujin karaa mitir ama cutubyo boqortooyo. Qodobbada heeganka ah ee digniinta iyo khatarta ayaa ah kuwo si buuxda u barnaamijsan kara, sida wakhtiga digniinta dib u dhigista, miyir-beelka iyo haynta. Heerarka Feejignaanta iyo Khatarta ayaa sidoo kale lagu waafajin karaa shaqada xawaaraha ama macluumaad kasta oo dibadda ah.

Wax soo saarka dhijitaalka ah ayaa laga heli karaa gudaha gudaha (kaarka wax-soo-saarka IOC4T ee u dhigma) heer kasta oo digniin ah. Calaamadaha digniinahani waxay ku wadi karaan afar gudbinta maxalli ah ee kaarka IOC4T iyo/ama waa la marin karaa iyada oo la adeegsanayo baska VM600 rack's Raw baska ama baska Furan (OC) si loogu kaxeeyo wareejinta kaararka ikhtiyaarka ah sida RLC16 ama IRC4.

Calaamadaha firfircoonida (gariirka) ee la farsameeyay iyo calaamadaha xawliga ayaa laga heli karaa xagga danbe ee rafka (guriga hore ee IOC4T) sida calaamadaha wax soo saarka analoogga ah. Calaamadaha ku salaysan korantada (0 ilaa 10 V) iyo hadda ku salaysan (4 ilaa 20 mA) ayaa la bixiyaa. MPC4 waxay qabataa is-imtixaanka iyo baaritaanka joogtada ah ee kor u qaadista. Intaa waxaa dheer, kaarka lagu dhex dhisay "Nidaamka OK" wuxuu si joogto ah ula socdaa heerka calaamadaha ay bixiso silsiladda cabbiraadda (sensor iyo/ama conditioner signal) oo tilmaamaya dhibaato kasta oo ay sabab u tahay khadka gudbinta oo jabay, shidma cilladaysan ama qaboojiyaha.

Tilmaamaha LED-ka ee ku yaal guddiga hore ee MPC4 wuxuu muujinayaa in khalad habayn ama qalab uu dhacay. Lix LEDs oo dheeri ah (hal kiiba kanaal wax geliyo) ayaa muujinaya in Nidaamka OK uu ogaaday cillad iyo in alaarmiga uu ka dhacay kanaalka.

Kaadhka MPC4 waxa uu u kala baxaa saddex nooc: nooca “standard”, nooca “separate circuits” iyo nooca “nabdoonaanta” (SIL), kuwaas oo dhamaantood u shaqeeya sidii lammaane kaadh ah oo isticmaalaya kaarka wax-gelinta ee IOC4T ee u dhigma. Noocyada kala duwan ee kaadhka MPC4 Kaarka MPC4 waxa lagu heli karaa noocyo kala duwan, oo ay ku jiraan noocyada "standard", "separate circuits" iyo "nabadgelyada" (SIL).

Intaa waxaa dheer, noocyada qaar ayaa la heli karaa oo leh dahaar iswaafaqsan oo lagu dhejiyay wareegga kaadhka si loogu ilaaliyo deegaanka dheeraadka ah ee kiimikada, boodhka, qoyaanka iyo heerkulka ugu sarreeya. Nooca 'standard' iyo nooca "badbaadada" (SIL) ee kaarka MPC4 labaduba waxay shahaado u siiyeen IEC 61508 iyo ISO 13849, si loogu isticmaalo xaaladaha badbaadada shaqada, sida SIL 1 si waafaqsan IEC 61508 iyo PL c si waafaqsan ISO 13849-1. Kaarka MPC4 ee "standard" waa nooca asalka ah wuxuuna taageeraa dhammaan sifooyinka iyo hababka habaynta. "Heerka" MPC4 waxaa loogu talagalay nidaamyada badbaadada iyadoo la isticmaalayo VM600 rack oo leh tiro xaddidan oo kaararka ah, taas oo ah, "standard" MPC4/IOC4T lammaane iyo kaararka gudbinta RLC16. Waxay leedahay VME-ku-habboonaanta addoonta ku habboon sidaa darteed waa software lagu habeyn karo VME marka uu jiro kaarka CPUx oo u shaqeynaya sida kontaroolaha rack ee VM600 rack. Sidoo kale waa software lagu habeyn karo iyada oo loo marayo RS-232 (oo ku yaala dhinaca hore ee kaarka).

Kaarka "badbaadada" (SIL) MPC4, oo loo yaqaan MPC4SIL, ayaa loo sameeyay si loo oggolaado xulashooyin rakibid oo ballaaran. Gaar ahaan, VM600 racks oo waliba ay ku jiraan kaararka la socodka xaalada sida XMx16 iyo kaararka gudbinta sida IRC4. Si loo caddeeyo qaabayntan, waxay ahayd lagama maarmaan in la hubiyo in MPC4SIL ay ka go'do kaadhadhka kale ee ku jira VM600 rack, si aanay suurtogal u ahayn in qaabayntiisa si badheedh ah wax looga beddelo. Sidaa darteed, kaarka MPC4SIL kuma jiraan VME-ku-xiran is-dhexgalka addoonta, ma taageerayo kanaalada tachometer-ka (xawaaraha) mana bixiyo dhammaan awoodaha farsamaynta calaamadaha ee kaadhka MPC4 "standard" (eeg faahfaahin dheeraad ah - ee "standard" iyo "wareegyo gooni ah" kaararka MPC4 oo keliya bogga 9). Kala soocida MPS iyo CMS VM600 rack, kaadhadhka ilaalinta mishiinada, kaadhadhka la socodka xaalada iyo software la xidhiidha waxa loogu talagalay u hogaansanaanta nidaamka ilaalinta mishiinka (MPS) iyo nidaamka la socodka xaalada (CMS) shuruudaha kala soocida API 670, kaas oo hubinaya in shaqaynta MPS aanay ku xidhnayn oo aan loo wiiqin sinaba hawlgalka CMS. Marka in kasta oo kaadhadhka ilaalinta mashiinada iyo kaadhadhka la socodka xaalada ay si fudud u wadaagi karaan calaamadaha dareemayaasha ee silsiladaha cabbiraadda, lammaaneyaasha kaadhka MPC4/IOC4T lama wadaagayaan wax basaska isgaadhsiinta ah ee lammaanaha kaarka kormeerka ee XMx16/XIO16T ee ku jira VM600 rack, iyo lammaaneyaasha kaadhka MPC4/IOC4T waa la habeeyey oo lagu shaqeeyaa iyada oo la adeegsanayo software-ka VM600leX/6TIO MPSx1 habeeyey oo lagu hawlgaliyey iyadoo la isticmaalayo software-ka VibroSight®). Macluumaadka codsiyada Marka loo isticmaalo lammaane kaar oo leh kaarka wax-ku-gelinta/soo-saarka IOC4T, MPC4 waxay aad ugu habboon tahay la socodka iyo ilaalinta mashiinnada noocyo badan oo codsiyo warshadeed ah.
