Ino PLC ninzi?
PLC nchifwiinsyo cha Programmable Logic Controller.
Chibelesyo chakubelesya magesi chikonzya kubelesegwa munzila ya dijitali chakapangwa kuti chibelesegwe mumafakitali.Ibelesya musyobo wa memory iikonzya kubelesegwa, eeyo ibamba malailile aakuchita milimo ya logic, kweendelezya kweendelana, chiindi, kubala antoomwe akubelesya namba, mpawo yeendelezya misyobo isiyene-siyene ya zibelesyo zyaminchina naakuti nzila yakupanga zintu kwiinda mukubelesya minchina naakuti analogi.
Zibeela zya PLC
1.Kusyomeka kupati
Nkaambo kakuti PLC kanjikanji ibelesya kkompyuta yomwe, ilijisi kujatana kupati, antoomwe amaseketi aakukwabilila alimwi amilimo yakulilanga-langa, calo cisumpula kusyomeka kwanzila.
2. Kubamba mapulogilamu kuuba
Ipulogilamu ya PLC kanjikanji ibelesya chikozyano cha relay control ladder antoomwe a command statement, mpawo mweelwe wayo muniini kwiinda wa microcomputer. Mukuyungizya ku PLCs zili akati-akati azyaatala, kuli buyo 16 PLCs ziniini. Nkaambo kakuti mufanikisyo wamatantilo ulasalala alimwi nguuba-uba, ncuuba-uba kuzyiba akubelesya. ilakonzya kuchitwa kakwiina luzibo lwachikompyuta.
3.Kubamba zintu zikonzya kuchincha
Mbwaanga PLC ibelesya nzila yakuyaka, babelesyi balakonzya kuchincha mulimo abupati bwenzila yakulela kwiinda mukuziswaanganya biyo. Aboobo, ilakonzya kubelesegwa kuli zyoonse zyeendelezya.
4.Zuzikizya zyintu zyakunjizya / kugwisya
Bubotu bumwi bupati bwa PLC mbwakuti kuzitondezyo zyamumuunda ziindene-indene (mbuli DC naa AC, mweelwe wakucinca, mweelwe wa digital naa analog, voltage naa current, azimwi), kuli zitondezyo zyeendelana, zikonzya kuswaangana azibelesyo zyamumuunda (mbuli mabbatani, ma switch, zibelesyo zyakuzyiba current transmitters, starters naa control, mavalvu azimwi) zijatikizyidwe a CPU alimwi a motherboard kwiinda mu motherboard.
5.Kubikka kuuba
Kweezyanisya anzila yakkompyuta, kubikka PLC takuyandiki ŋanda yakkompyuta yaalubazu naakuti nzila zyakukwabilila ziyumu. Niibelesyegwa, ilakonzya kubeleka kabotu biyo kwiinda mukuswaanganya kabotu chibelesyo chakuzyiba a I / O interface terminal ya actuator a PLC.
6.Kuchijaana chakufwambaana
Nkaambo kakuti kweendelezya kwa PLC kuchitwa akweendelezya kwapulogilamu, kusyomeka kwayo akufwambaana kwayo takukonzyi kweezyanisyigwa akweendelezya kwa relay logic. Muminyaka misyoonto yainda, kubelesya ma microprocessors, ikapati amweelwe mupati wama microcomputer aajisi chip yomwe, kwasumpula kapati manguzu aa PLC, mpawo kwapa kuti kwiimpana aakati ka PLC a microcomputer control system kucheya, ikapati PLC iili kabotu.
Mbuli mbomukonzya kubona muvidiyo, kusanganya kwaminchina, muuya amagesi, zyoonse zibeleka zyeendelezyegwa a PLC. Touch screen ipa kuti kube kuchita obotu akuubauba. Mbuli GTMSMART Machine, tulazumanana kusumpula zintu zyesu atekkinoloji mpya mpawo tulachita obotu muchini wapulasitiki wakupyasya eezyo ziyookkomanisya basikuula besu.
