Zennio Iigalelo zeAnalog yeModyuli yoMsebenzisi
1. INTSHAYELELO
Iintlobo ngeentlobo zezixhobo zeZennio zibandakanya ujongano lwegalelo apho kunokwenzeka ukudibanisa igalelo le-analog kunye noluhlu olwahlukileyo lokulinganisa:
– Voltage (0-10V, 0-1V y 1-10V).
– Okwangoku (0-20mA y 4-20mA).
Kubalulekile:
Ukuze uqinisekise ukuba isixhobo esithile okanye inkqubo yenkqubo idibanisa umsebenzi wegalelo le-analog, nceda ubhekisele kwincwadana yomsebenzisi wesixhobo, njengoko kunokubakho umahluko omkhulu phakathi kokusebenza kwesixhobo ngasinye seZennio. Ngaphezu koko, ukufikelela kwi-analog eyiyo yegalelo lomsebenzisi, kuhlala kucetyiswa ukusebenzisa amakhonkco athile okhuphelo anikezwe kwiZennio. webindawo (www.zennio.com) ngaphakathi kwecandelo lesixhobo esithile esilungiselelwe iparamitha.
2 UKULUNGISWA
Nceda uqaphele ukuba imifanekiso-skrini kunye namagama ezinto aboniswe ngokulandelayo anokwahluka kancinane ngokuxhomekeke kwisixhobo nakwinkqubo yesicelo.
Emva kokwenza imodyuli ye-Analog Input, kwithebhu yoqwalaselo jikelele lwesixhobo, ithebhu "I-Analog Input X" yongezwa kumthi wasekhohlo.
2.1 IGALELO LE-ANALOG X
Igalelo le-analog liyakwazi ukulinganisa zombini umthamotage (0…1V, 0…10V o 1…10V) kunye yangoku (0…20mA o 4…20mA), enikezela ngeendidi zesignali ezahlukeneyo ukuze zilungele isixhobo esiqhagamshelweyo. Uluhlu lwezinto zempazamo zingenziwa ukuba zaziswe xa le milinganiso yegalelo ingaphandle kolu luhlu.
Xa igalelo livuliwe, into ethi "[AIx] Ixabiso eliLinganisiweyo" livela, elinokuba leefomati ezahlukeneyo ngokuxhomekeke kwiparamitha ekhethiweyo (jonga kwiThebhile 1). Le nto iya kwazisa ixabiso langoku legalelo (ngezihlandlo okanye emva kokunyuka / ukucutha okuthile, ngokuhambelana noqwalaselo lweparameter).
Imida inokuthi iqwalaselwe, oko kukuthi, unxibelelwano phakathi kobuninzi kunye nexabiso elincinci loluhlu lokulinganisa umqondiso kunye neyona nto yexabiso lenzwa.
Ngakolunye uhlangothi, kuya kwenzeka ukuba kuqwalaselwe into ye-alamu xa amaxabiso athile e-threshold agqithwa ngaphezulu okanye ngaphantsi, kunye ne-hysteresis yokuphepha utshintsho oluphindaphindiweyo xa i-signal oscillates phakathi kwamaxabiso asondele kwi-threshold values. La maxabiso aya kwahluka ngokuxhomekeke kwifomathi ekhethiweyo yesignali yokufaka (jonga iTheyibhile 1).
Isixhobo esinemodyuli esebenzayo ye-analog iya kubandakanya isalathisi se-LED esihambelana negalelo ngalinye. I-LED iya kuhlala ivaliwe ngelixa ixabiso elilinganisiweyo lingaphandle koluhlu lomlinganiselo weparameterised kwaye ngelixa lingaphakathi.
ETS PARAMETERISATION
Udidi Lwegalelo [Voltage / Okwangoku]
Ukukhetha oku-1 kohlobo lophawu oluza kulinganiswa. Ukuba ixabiso elikhethiweyo ngu “Voltage”:
➢ Uluhlu loMlinganiso [0…1 V / 0…10 V / 1…10 V]. Ukuba ixabiso elikhethiweyo lithi "Yangoku":
➢ Uluhlu loMlinganiso [0…20 mA / 4…20 mA].
Uluhlu lweZinto zeMposiso [Ikhubazekileyo / Yenziwe]: yenza into enye okanye ezimbini zempazamo (“[AIx] Impazamo yoHlanga oluPhantsi” kunye/okanye “[AIx] impazamo yoLuhlu oluPhezulu”) eyazisa ixabiso elingaphandle koluhlu ngokuthumela ixabiso ngamaxesha athile. “1”. Nje ukuba ixabiso lingaphakathi koluhlu olucwangcisiweyo, i-"0" iya kuthunyelwa ngezi zinto.
IFomathi yokuThumela yoMlinganiselo [1-Byte (Ipesentitage) / 1-Byte (Ayibhalwanga) /
I-1-Byte (Isayinwe) / 2-Byte (Engasayinwanga) / 2-Byte (isayiniwe) / 2-Byte (Float) / 4-Byte (Float)]: ivumela ukukhetha ifomathi ye[AIx] Ixabiso eliLinganisiweyo” into.
Iyathumela Ixesha [0…600…65535][s]: limisela ixesha eliya kudlula phakathi kokuthunyelwa kwexabiso elilinganisiweyo ebhasini. Ixabiso "0" lishiya oku kuthunyelwa kwephetshana kuvaliwe.
Thumela ngoTshintsho lwexabiso: ichaza i-threshold ukwenzela ukuba nanini na ixabiso elitsha lokufunda lihluke kwixabiso langaphambili elithunyelwe ebhasini ngaphezu komda ochaziweyo, ukuthunyelwa okongeziweyo kuyakwenzeka kwaye ixesha lokuthumela liyakuqala kwakhona, ukuba liqwalaselwe. Ixabiso "0" livala oku kuthumela. Ngokuxhomekeke kwifomathi yomlinganiselo, iya kuba noluhlu oluhlukeneyo.
Imida.
➢ Elona xabiso liphantsi. Imbalelwano phakathi kwexabiso eliphantsi loluhlu lokulinganisa umqondiso kunye nexabiso elincinci lento eza kuthunyelwa.
➢ Elona xabiso Liphezulu Lemveliso. Imbalelwano phakathi kwexabiso eliphezulu loluhlu lokulinganisa umqondiso kunye nexabiso eliphezulu lento eza kuthunyelwa.
Umqobo.
➢ I-Object Threshold [I-Threshold ekhubazekileyo / esezantsi / i-Upper Threshold / Lower and Upper Threshold].
- Umda osezantsi: Iiparamitha ezimbini ezongezelelweyo ziya kuvela:
o Lower Threshold Value: ubuncinane bexabiso elivumelekileyo. Ufundo olungaphantsi kweli xabiso luya kuxhokonxa ukuthunyelwa kwexesha ngexabiso “1” nge[AIx] Lower Threshold” into, rhoqo ngemizuzwana engama-30.
o I-Hysteresis: Ibhanti efileyo okanye ithreshold ejikeleze ixabiso elisezantsi lomqobo. Le bhendi efileyo ikhusela isixhobo ekuthumeleni ngokuphindaphindiweyo i-alam kunye ne-alam, xa ixabiso legalelo langoku lihlala liguquguquka malunga nomda osezantsi. Emva kokuba i-alamu esezantsi iqalisiwe, i-alam ayiyi kuthunyelwa kude kube ixabiso langoku likhulu kunexabiso elisezantsi kunye ne-hysteresis. Xa kungekho alarm, i-“0” (kanye) iya kuthunyelwa ngento enye. - Upper Threshold: Iiparamitha ezimbini ezongezelelweyo ziya kuza:
o Upper Threshold Value: ixabiso eliphezulu livumelekile. Ukufunda okungaphezulu kweli xabiso kuya kuxhokonxa ukuthunyelwa kwexesha ngexabiso "1" nge-[AIx] Upper Threshold” into, rhoqo ngemizuzwana engama-30.
o I-Hysteresis: Ibhanti efileyo okanye ithreshold ejikeleze ixabiso eliphezulu. Njengakwi-threshold esezantsi, xa i-alarm ephezulu iqalisiwe, i-no-alarm ayiyi kuthunyelwa kude kube ixabiso langoku liphantsi kunexabiso eliphezulu le-threshold thabatha i-hysteresis. Xa kungekho alarm, i-“0” (kanye) iya kuthunyelwa ngento enye. - I-Threshold esezantsi kunye nePhezulu: Ezi parameters zilandelayo ziya kuvela:
o Ixabiso elisezantsi.
o Ixabiso eliPhezulu.
o Ukuphazamiseka kwentliziyo.
Zontathu ziyafana nezidlulileyo.
➢ I-Threshold Value Objects [Ikhubazekileyo / Yenziwe]: yenza ukuba into enye okanye ezimbini (“[AIx] Ixabiso Eliphantsi Lomqobo” kunye/okanye “[AIx] Ixabiso Eliphezulu Lomqobo”) ukutshintsha ixabiso lemiqobo ngexesha lokusebenza.
Uluhlu lwamaxabiso avumelekileyo eparameters luxhomekeke kwi "Measurement Sending Format", olu luhlu lulandelayo ludwelisa amaxabiso anokubakho:
| Ifomathi yomlinganiselo | Uluhlu |
| I-1-Byte (Ipesentitage) | [0…100][%] |
| I-1-Byte (Ayibhalwanga) | [0…255] |
| 1-Byte (isayiniwe) | [-128...127] |
| I-2-Byte (Ayibhalwanga) | [0…65535] |
| 2-Byte (isayiniwe) | [-32768...32767] |
| 2-Byte (Float) | [-671088.64...670433.28] |
| 4-Byte (Float) | [-2147483648...2147483647] |
