MODBUS RTU yava kushanda neEthernet communication
Nhanganyaya: Kudiwa kweIndustrial Ethernet muIndustry 4.0 Era
Indasitiri 4.0 inguva yehungwaru hunowanikwa kuburikidza nekushandiswa kwetekinoroji yeruzivo. Mafekitori akangwara ndeimwe yenzvimbo huru dzekushandiswa kweIndasitiri 4.0, achishandisa zvishandiso zvakangwara uye tekinoroji yeruzivo kuti awane otomatiki, hungwaru, uye kuchinjika mumaitiro ekugadzira nekutarisira. Kubatanidza michina yakasiyana-siyana yekugadzira, plcs, masensa, zvishandiso, marobhoti emaindasitiri, maturusi emuchina weCNC, nezvimwe zvishandiso zviri mufekitori yakangwara kuti zvibudirire pakubatana kwemidziyo uye kugovera data, nokudaro zvichibudirira kushanda pamwe chete uye kugadzirisa manejimendi, zvinobatsira kuvandudza kushanda zvakanaka kwekugadzira, kuderedza mari yekugadzira, uye kusimudzira mhando yechigadzirwa.
Maitiro ekuwana kubatana kwemaindasitiri uye kugonesa MODBUS RTU kutaurirana kuburikidza nema network ports?
Chii chinonzi Modbus RTU?
Modbus RTU inzira yekutaurirana inoshandiswa kubatanidza zvishandiso zvemagetsi zveindasitiri zvakaita se programmable logic controllers (PLCs), sensors, actuators, nezvimwewo. Iyi nzira inotsanangura chimiro chemeseji chinobvumira kutaurirana pakati pemidziyo iyi kuti iwane data uye kutevedzera mirayiridzo yekudzora. Zvinhu zvikuru zveModbus RTU protocol zvinosanganisira:
·Kutaurirana kweseriya: Inoshandisa nzira yekutaurirana seriya uye yakakodzera kutaurirana pakati pemidziyo kuburikidza nekubatana kwepanyama senge RS-232, RS-485, nezvimwewo.
·Maitiro emuranda mukuru: Kutaurirana kwakavakirwa pahurongwa hwemuranda mukuru, apo chimwe chishandiso chinoshanda semukuru uye chine mutoro wekutanga zvikumbiro zvekutaurirana, nepo zvimwe zvishandiso zvichishanda sevaranda uye zvichipindura zvikumbiro zvetenzi.
·Maumbirwo emeseji: anotsanangura maumbirwo emeseji, kusanganisira kero yemudziyo, kodhi yebasa, data, uye kutarisa zvikanganiso, kuve nechokwadi chekutumirwa uye kugadziriswa kweruzivo kwakakodzera.
·Kuenderana kwakafara: Chibvumirano cheModbus RTU chinoshandiswa zvakanyanya mumasisitimu akasiyana-siyana ekugadzira otomatiki eindasitiri nekuda kwekuvhurika kwayo uye nyore kwayo kuita.
Musiyano uripo pakati peModbus RTU neModbus TCP
Modbus RTU neModbus TCP nzira mbiri dzakasiyana dzekutaurirana, dzine musiyano mukumhanya kwekutumira data, nzira dzekutumira data, uye mamiriro ezvinhu anoshanda. Modbus RTU inonyanya kukodzera kutumira data pakati pemidziyo iri kure, nepo Modbus TCP inonyanya kukodzera kutumira data panguva chaiyo pakati pemidziyo.
Kuzvigadzira otomatiki kwemaindasitiri
Nekuenderera mberi kwekuvandudzwa kwekushandiswa kwemagetsi mumaindasitiri, Modbus RTU inoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yekushanda kwemaindasitiri, yakadai sePLC, masensa, nezvimwewo. Kuburikidza neModbus RTU, tinogona kuwana kutariswa nekudzora kuri kure, tichivandudza kushanda zvakanaka kwekugadzira.
Indaneti yezvinhu
Kuvandudzwa kwetekinoroji yeIoT kwakapawo mamwe mashandisirwo akawanda eModbus RTU. Nekubatanidza zvishandiso zvakasiyana-siyana kune network, tinogona kuwana kutariswa nekudzorwa kwemidziyo iri kure, tichivandudza hunyanzvi hwayo.
Mimwe minda
Kuwedzera kune otomatiki yeindasitiri uye Internet yezvinhu, Modbus RTU inogonawo kushandiswa mune dzimwe nzvimbo dzakadai semaguta akangwara, kutakurwa kwakangwara, dzimba dzakangwara, nezvimwewo.
MODBUS RTU inogona kutaurirana zvakare kuburikidza nema Ethernet ports here?
Kuzvigadzira otomatiki kwemaindasitiri
Kune michina yakasiyana-siyana yakakura pamusika inogona kushandura MODBUS RTU (serial port) kuita MODBUS TCP (Ethernet interface) yekutaurirana, inowanzozivikanwa se protocol converters, gateways, kana serial servers. Heano mamwe marudzi ezvigadzirwa zvakajairika:
1. Modbus Protocol Gateway: Magedhi aya anotsigira mapuroteni akawanda eModbus, anosanganisira Modbus TCP/RTU/ASCII, uye ane hunyanzvi hwekushandura mapuroteni.
2. Protocol Converter: Rudzi urwu rwemudziyo runogona kushandura MODBUS RTU protocol kuita MODBUS TCP/IP protocol, zvichiita kuti data ritumirwe kuburikidza neEthernet.
3. Serial port server: Serial port server mudziyo unogona kushandura serial communication kuita network communication, zvichibvumira MODBUS RTU devices kutaurirana pamusoro penetwork.
4. Interface Converter: Mamwe ma interface converters anokwanisa kushandura pakati peModbus RTU neModbus TCP.
5. Indaneti IoT gateway: Midziyo iyi haingotsigire chete kushandurwa kweprotocol, asiwo inopa mamwe mabasa eIoT, akadai sekuunganidza data, edge computing uye cloud connection. Mhinduro iyi yakavakirwa papuratifomu yekutonga kodhi yakaderera yataurwa muchikamu ichi inogona kurerutsa maitiro ekugadzira, kuderedza mari, uye kuvandudza mashandiro ekugadzira.
Dhayagiramu yekutaurirana
Kuti uwane kutaurirana kweModbus RTU kuburikidza nema Ethernet ports, serial to Ethernet converter inowanzo dikanwa.
Mudhayagiramu iyi, mudziyo we serial wakabatana ne converter kuburikidza ne RS-485 interface. Converter iyi inoshandura mapaketi eModbus RTU protocol kuita Modbus TCP/IP format uye inoatumira kune network kuburikidza ne Ethernet. Mushure mekugamuchira data, mudziyo unogamuchira unoita mabasa kana mhinduro dzinoenderana.
Mugumo
Modbus RTU ine mabhenefiti akawanda ekutumira maremote, anosanganisira mutengo wakaderera, kushanda zvakanaka kwekutumira maremote, uye kugona kwakasimba kwekudzivirira kukanganiswa. Mune ramangwana, nekuvandudzwa kuri kuitwa matekinoroji akadai seInternet of Things uye low code, kusanganiswa kwemaports eModbus RTU neEthernet kuchashandiswa zvakanyanya, zvichipa rutsigiro rwakasimba kune otomatiki yeindasitiri uye hungwaru.
Mune ramangwana, pachava nemidziyo yeIoT yakawanda, uye kutapurirana kwedata kuchava nyaya yakakosha kumaapplication eIoT. Nekubatanidza Modbus RTU nemaports eEthernet, kutapurirana kwedata kwemidziyo yakasiyana-siyana yeIoT kunogona kuitwa, zvichizadzisa zvinodiwa zvekutapurirana kwedata mumamiriro akasiyana. Panguva iyi, nekuvandudzwa kwekodhi yakaderera nedzimwe tekinoroji, kutapurirana kwedata kuchava nyore, nekukurumidza, uye kunoshanda zvakanyanya. Nokudaro, kusanganiswa kweModbus RTU nemaports eEthernet kuchaita basa rakakosha mumaapplication eIoT emangwana uye kuve netariro yakakura yekushandisa.
