Imanuwali yomsebenzisi ye-Zennio Analog Inputs
1 ISINGENISO
Izinhlobonhlobo zamadivayisi we-Zennio ahlanganisa okokufaka okusetshenziswayo lapho kungenzeka khona ukuxhuma okokufaka kwe-analog okukodwa noma ngaphezulu ngobubanzi obuhlukahlukene bokulinganisa:
– Voltage (0-10V, 0-1V y 1-10V).
- Yamanje (0-20mA y 4-20mA).
Okubalulekile:
Ukuze uqinisekise ukuthi idivayisi ethile noma uhlelo lokusebenza luhlanganisa umsebenzi wokufakwayo kwe-analogi, sicela ubheke incwadi yomsebenzisi wedivayisi, njengoba kungase kube nomehluko omkhulu phakathi kokusebenza kwedivayisi ngayinye ye-Zennio. Ngaphezu kwalokho, ukuze ufinyelele kumanuwali afanele wokufakwa kwe-analogi, kuyanconywa ukuthi usebenzise izixhumanisi zokudawuniloda ezihlinzekwe eZennio. webisayithi (www.zennio.com) ngaphakathi kwesigaba sedivayisi ethile ebekwa ipharamitha.
2 UKULUNGISWA
Sicela uqaphele ukuthi izithombe-skrini namagama ezinto aboniswa ngokulandelayo angase ahluke kancane kuye ngedivayisi kanye nohlelo lohlelo lokusebenza.
Ngemva kokunika amandla imojuli Yokokufaka kwe-Analog, kuthebhu yokucushwa evamile yedivayisi, ithebhu ethi “I-Analog Input X” yengezwa esihlahleni esingakwesokunxele.
2.1 OKUFAKAYO KWE-ANALOGU X
Okokufaka kwe-analogi kuyakwazi ukukala kokubili ivolumutage (0…1V, 0…10V o 1…10V) neyamanje (0…20mA o 4…20mA), enikeza ububanzi besignali yokufaka ehlukile ukuze ifanele idivayisi exhunyiwe. Izinto zephutha lobubanzi zinganikwa amandla ukuze zaziswe uma lezi zilinganiso zokufaka zingaphandle kwalezi zinhlanga.
Uma okokufaka kunikwe amandla, into ethi “[AIx] Inani Elilinganiselwe” iyavela, okungenzeka ibe ngamafomethi ahlukene kuye ngepharamitha ekhethiwe (bona Ithebula 1). Le nto izokwazisa inani lamanje lokokufaka (ngezikhathi ezithile noma ngemva kokunyuka/ukwehla okuthile, ngokuya ngokucushwa kwepharamitha).
Imikhawulo ingabuye imiswe, okungukuthi, ukuxhumana phakathi kwenani eliphakeme nelincane lebanga lokulinganisa isignali kanye nento yenani langempela lenzwa.
Ngakolunye uhlangothi, kuzokwazi ukulungisa into ye-alamu lapho amanani athile e-threshold eqiwe ngenhla noma ngezansi, kanye ne-hysteresis yokugwema izinguquko eziphindaphindiwe lapho isignali i-oscillates phakathi kwamanani aseduze namanani e-threshold. Lawa manani azohluka kuye ngefomethi ekhethelwe isignali yokufaka (bona Ithebula 1).
Idivayisi enemojuli esebenzayo yokokufaka kwe-analog izohlanganisa inkomba ye-LED ehlotshaniswa nokokufaka ngakunye. I-LED izohlala ivaliwe kuyilapho inani elilinganisiwe lingaphandle kwebanga lokulinganisa elinepharamitha futhi livuliwe ngenkathi ingaphakathi.
I-ETS PARAMETERISATION
Uhlobo Lokufaka [Ivolumutage / Yamanje]
Ukukhetha oku-1 kohlobo lwesignali oluzolinganiswa. Uma inani elikhethiwe lithi “Voltage”:
➢ Ibanga Lokulinganisa [0…1 V / 0…10 V / 1…10 V]. Uma inani elikhethiwe lithi “Okwamanje”:
➢ Ibanga Lokulinganisa [0…20 mA / 4…20 mA].
Izinto Zephutha Lebanga [Ikhutshaziwe / Inikwe amandla]: inika amandla into yephutha eyodwa noma ezimbili (“[AIx] Iphutha Lebanga Eliphansi” kanye/noma “[AIx] Iphutha Lebanga Eliphezulu”) elazisa inani elingaphandle kobubanzi ngokuthumela inani ngezikhathi ezithile. “1”. Uma inani selingaphakathi kwebanga elimisiwe, u-“0” uzothunyelwa ngalezi zinto.
Ifomethi Yokuthumela Isikali [1-Byte (Amaphesentitage) / 1-Byte (Akusayiniwe) /
I-1-Byte (Isayiniwe) / 2-Byte (Ayisayiniwe) / 2-Byte (Isayiniwe) / 2-Byte (Float) / 4-Byte (Float)]: ivumela ukukhetha ifomethi yokuthi “[AIx] Inani Elilinganiselwe” into.
Iyathumela Isikhathi [0…600…65535][s]: simisa isikhathi esizodlula phakathi kokuthunyelwa kwevelu elinganisiwe ebhasini. Inani elithi “0” lishiya lokhu kuthumela ngezikhathi ezithile kukhutshaziwe.
Thumela nge-Value Change: ichaza i-threshold ukuze noma nini lapho inani elisha lokufunda lihluka kunani langaphambilini elithunyelwe ebhasini ngaphezu komkhawulo ochaziwe, ukuthunyelwa okwengeziwe kuzokwenzeka futhi isikhathi sokuthumela sizoqala kabusha, uma simisiwe. Inani "0" likhubaza lokhu kuthumela. Ngokuya ngefomethi yesilinganiso, izoba nobubanzi obuhlukile.
Imikhawulo.
➢ Inani Elincane Lokukhiphayo. Ukuxhumana phakathi kwenani eliphansi lobubanzi bokulinganisa isignali kanye nenani elincane lento ezothunyelwa.
➢ Inani eliphezulu Lokukhiphayo. Ukuxhumana phakathi kwenani eliphakeme lobubanzi bokulinganisa isignali kanye nenani eliphezulu lento ezothunyelwa.
Umkhawulo.
➢ I-Object Threshold [I-Threshold Ekhubazekile / Ezansi / I-Upper Threshold / Ephansi Nangaphezulu].
- I-Lower Threshold: Amapharamitha amabili engeziwe azovela:
o I-Lower Threshold Value: inani elincane elivunyelwe. Ukufundwa okungaphansi kwalelivelu kuzovusa ukuthunyelwa ngezikhathi ezithile ngevelu ethi “1” ngento ethi “[AIx] Lower Threshold”, njalo ngamasekhondi angu-30.
o I-Hysteresis: i-dead band noma i-threshold ezungeze inani eliphansi le-threshold. Le bhendi efile ivimbela idivayisi ekuthumeleni i-alamu ngokuphindaphindiwe kanye ne-alamu, lapho inani lamanje lokokufaka lihlala liguquguquka eduze komkhawulo ophansi. Uma i-alamu ye-threshold ephansi isicushiwe, i-alamu engekho ngeke ithunyelwe kuze kube yilapho inani lamanje likhulu kunenani eliphansi le-threshold kanye ne-hysteresis. Uma ingekho i-alamu, u-“0” (kanye) uzothunyelwa ngento efanayo. - I-Upper Threshold: Amapharamitha amabili engeziwe azovela:
o I-Upper Threshold Value: inani eliphezulu elivunyelwe. Ukufundwa okukhulu kunalelivelu kuzovusa ukuthunyelwa ngezikhathi ezithile ngevelu ethi “1” ngento ethi “[AIx] Upper Threshold”, njalo ngemizuzwana engama-30.
o I-Hysteresis: ibhande elifile noma i-threshold ezungeze inani eliphezulu lomkhawulo. Njengakwi-threshold engezansi, uma i-alamu yomkhawulo ongaphezulu isicushiwe, i-no-alamu ngeke ithunyelwe kuze kube inani lamanje liphansi kunevelu yomkhawulo ongaphezulu kukhishwe i-hysteresis. Uma ingekho i-alamu, u-“0” (kanye) uzothunyelwa ngento efanayo. - I-Threshold Ephansi Nangaphezulu: Imingcele eyengeziwe elandelayo izovela:
o Lower Threshold Value.
o I-Upper Threshold Value.
o I-Hysteresis.
Zontathu ziyafana nezangaphambili.
➢ I-Threshold Value Objects [Ikhutshaziwe / Inikwe amandla]: yenza into eyodwa noma ezimbili (“[AIx] I-Lower Threshold Value” kanye/noma i-[AIx] I-Upper Threshold Value”) iguqule inani lama-threshold ngesikhathi sokusebenza.
Ububanzi bamanani avunyelwe amapharamitha buncike “Kufomethi Yokuthumela Ukulinganisa” ekhethiwe, ithebula elilandelayo lifaka uhlu lwamanani okungenzeka:
| Ifomethi yokulinganisa | Ibanga |
| I-1-Byte (Amaphesentitage) | [0…100][%] |
| 1-Byte (Akusayiniwe) | [0…255] |
| I-1-Byte (isayiniwe) | [-128...127] |
| 2-Byte (Akusayiniwe) | [0…65535] |
| I-2-Byte (isayiniwe) | [-32768...32767] |
| 2-Byte (Float) | [-671088.64...670433.28] |
| 4-Byte (Float) | [-2147483648...2147483647] |
Ithebula 1. Ububanzi bamanani avunyelwe
