Ukubuka konke kwezobuchwepheshe kwe-PLC: Ukuhlukaniswa, amamethrikhi okusebenza kanye nezitayela ezizayo

Ukuqonda ukuhlukaniswa kwe-PLC
Abalawuli abanezinhlelo (ama-PLCs) bahlukaniswe ngezigaba ngokususelwa Ukwakheka ngokomzimba na- I / o umthamo:

1. Ngesakhiwo:

• Ihlanganisiwe / I-Intanethi I-PLCS: Isici sokuhlinzekwa kwamandla, i-CPU, kanye ne-I / OMAFTS EZIHLOKO EBONAKALAYO. Ilungele izinhlelo zokusebenza ezihlangene.

• Ama-PLCs afakwe ku-modular / ama-rack Inikeza ukuguquguquka okuphezulu kwezinhlelo eziyinkimbinkimbi ngokuvumela ukukhetha okuhambisana ne-module ehambisanayo.

2. Nge-I / O umthamo:

• Ama-PLC amancane: phatha ≤ 256 Amaphoyinti. Isibonelo: I-Nokia S7-200 smart.

• Ama-PLC aphakathi: ngokujwayelekile, ukuphathwa 256 - 1024 I / Points. Isibonelo: Oconons S7-300.

• Ama-PLC amakhulu: Phatha> 1024 I / O. Isibonelo: Nokia S60 7-400.

1024 I / O. Isibonelo: Nokia S60 7-400.
Izinkomba Zokusebenza Ezibalulekile Zomsebenzi we-PLC

1. Ngenkathi abathengisi benikela ngezici ezihlukile, amamethrikhi asebenza kahle angu-Core Universal:

2. Umthamo we-I / O Point: Inani eliphelele lokufaka kanye nokukhipha ama-terminals achaza isikali sokulawula i-PLC. Kuyisici sokukhethwa esibucayi.

3. Ijubane lokuskena: Ukukala ukusebenza kahle kokubulawa, okuvezwe njengesikhathi (MS) kuyadingeka ukucubungula izinyathelo zohlelo lwe-1K (Isinyathelo 1 = 1 Ikheli lememori).

4. I-Memory Phorac: Ibonisa isitoreji sohlelo lomsebenzisi, olulinganiswe ngamagama we-K (kw), k byte (kb), noma k bits (Kbit) (1K = 1024). Amanye ama-PLCs acacisa umthamo ngezinyathelo (e.g., Mitsubishi FX2N-4SMR: 8000 Izinyathelo). Amandla avame ukulungiswa noma anwetshwe.

5. Isethi yokufundisa: Ububanzi kanye nobunyoninco bemiyalo etholakalayo banquma ukufakwa kwezinsiza namandla asebenzayo.

6. Amarejista angaphakathi / Ukudlulisela: Ubuningi bamarejista wokugcina okuguqukayo, idatha, kanye nemiphumela ephakathi nemiphumela yokuphatha uhlelo lokuxazulula uhlelo.

Amandla okukhulisa: amandla okuhlanganisa amamojula akhethekile (A / D, D / A, i-Counter ephezulu, ukuxhumana) kuthuthukisa kakhulu ukusebenza kwe-PLC.
Amasistimu wokulawula asekelwe PLC vs

Ngaphambi kwama-PLC, amasistimu asuselwa edluliselwe ephethwe yi-logic kanye nokulawulwa okulandelanayo. Ngenkathi zilula futhi zibiza kakhulu, ama-PLCs anikela ngezinhlelo eziphakeme, ukuguquguquka, kanye namakhono okuxilonga, okuholela ekuthathekeni kwabo okusabalele kwe-automation eyinkimbinkimbi.
Ikusasa lobuchwepheshe be-PLC

1. Ukuthuthuka kwe-PLC kuthuthuka ngokushesha ezinkomba ezimbalwa zokhiye:

2. Ukusebenza okuthuthukile: Ijubane eliphakeme lokucubungula, amakhono amakhulu, namandla athuthukile.

3. Ukuhlanganiswa kwenethiwekhi: Izinqubomgomo Zokuxhumana Eziqinisiwe kanye Nezokuxhumana Kwezindawo Zokuxhumana Kwezimboni 4.0 / IOT.

4. I-compact futhi ifinyeleleke: Izinyawo ezincane, izindleko eziphansi, nokusebenziseka okwenziwe lula kokutholwa okubanzi.

5. Isoftware ethuthukile: izinhlelo ezinamandla kakhulu, ezibonakalayo zokuhlela kanye namathuluzi wokucushwa.

6. Amamojula akhethekile: Ukuqhubeka kokuthuthukiswa kwamamojula wezinhlelo zokusebenza ze-niche.

I-Virtualization & Miniaturization: Ukuvela kwama-plc asuselwa ku-PLC okususelwa ku-PLC kanye namamodeli we-Hardware e-Ultra-compact.
