Istraživanje kontrasta između CompactLogix i ControlLogix PLC-a

Exploring the Contrast Between CompactLogix and ControlLogix PLCs

Rockwell Automation je vodeći brend u industrijskoj automatizaciji, koji nudi raznoliku ponudu proizvoda od malih PLC-ova do velikih IoT modula. Rockwellovi PLC-ovi poznati su po svojoj robusnoj hardverskoj arhitekturi i softveru za programiranje prilagođenom korisniku. Među popularnim PLC-ovima s velikim I/O mogućnostima su CompactLogix i ControlLogix . U ovom ćemo članku istražiti razlike između marki CompactLogix i ControlLogix PLC.

ControlLogix protiv CompactLogix

CompactLogix je Rockwell kategorizirao kao mali kontrolni sustav, dok je ControlLogix klasificiran kao veliki kontrolni sustav. Ova razlika implicira da ControlLogix posjeduje naprednije IO rukovanje, memoriju i druge softverske značajke prilagođene velikim sustavima upravljanja u usporedbi s CompactLogix PLC-om.

CompactLogix PLC

Brojevi modela PLC-a

  • CompactLogix 5370 – počevši od serije 1769
  • CompactLogix 5380 – počevši od serije 5069
  • CompactLogix 5480 – počevši od serije 5069
  • ControlLogix 5570 – počevši od serije 1756
  • ControlLogix 5580 – počevši od serije 1756

Kapacitet memorije

ControlLogix se može pohvaliti maksimalnim kapacitetom memorije od 40 MB, dok CompactLogix doseže do 20 MB.

Broj ugrađenih Ethernet priključaka

ControlLogix može imati najviše dva ugrađena Ethernet priključka, dok CompactLogix podržava do tri ugrađena Ethernet priključka.

Redundancija

ControlLogix nudi mogućnosti redundantnosti, kojih nema u CompactLogix PLC-u. Stoga sustavi koji zahtijevaju redundantnost moraju koristiti ControlLogix PLC.

Sustav prikaza

ControlLogix ima sustav prikaza koji pruža podatke o dijagnostici i rješavanju problema. Nasuprot tome, CompactLogix PLC rješavanje problema je primarno putem LED dioda. Shodno tome, ControlLogix nudi poboljšane mogućnosti pregleda dijagnostike.

Podržani komunikacijski protokoli

ControlLogix podržava Ethernet/IP, ControlNet, DeviceNet, Remote I/O, SyncLink i USB. S druge strane, CompactLogix podržava EthernetI/P, USB i DeviceNet.

ControlLogix PLCs

Sercos Motion Support

ControlLogix PLC podržava Sercos standard za komunikaciju kretanja, široko korišten u projektima automatizacije strojeva, značajka koja nije dostupna u CompactLogix PLC-u.

Podrška za I/O točke

ControlLogix PLC podržava najviše 128.000 digitalnih i 4.000 analognih IO-ova, nadmašujući CompactLogix PLC.

Integrirani Displayport

CompactLogix PLC integrira priključak za prikaz koji omogućuje povezivanje s industrijskim monitorima visoke razlučivosti, što je značajka koja nedostaje u ControlLogix PLC-u.

Zaključak

Iako ControlLogix PLC ima inherentne prednosti zbog svojih mogućnosti velikog sustava, oba PLC-a nude brojne slične značajke prikladne za oštra, kritična i velika industrijska okruženja. Dakle, izbor između CompactLogixa i ControlLogixa ovisi o specifičnim zahtjevima projekta i potrebama skalabilnosti.
