Sengoliloeng sena se hlahloba kamoo litsamaiso tsa PLC li ntlafatsang katleho ea tlhahiso ka15–30%ha e ntse e netefatsa boleng bo tsitsitseng.(Mantsoe a bohlokoa a SEO: PLC indastering ea pampiri, mochini o ikemetseng oa pampiri, tlhahiso ea pampiri e bohlale)

1. Lits'ebetso tsa Bohlokoa tsa PLCs ho Tlhahiso ea Lipampiri

1.1 Taolo ea Boitokisetso ba Pulp

• Phetoho e iketsang ea lebelo la pulper(±0.5% ho nepahala)
• Tekanyo ea lik'hemik'hale e laoloang ke PID(8–12% chelete e bolokiloeng)
• Tlhokomelo ea nako ea sebele ea ho lumellana(0.1g/L ho nepahala)

1.2 Ho theha Maqephe le ho Tobetsa

• Taolo ea ho ntša metsi ka terata(<50ms karabo)
• Boima ba motheo/mongobo o koetsoeng oa taolo(CV <1.2%)
• Kabo ea mojaro oa khatiso ea libaka tse ngata(16-lintlha tsa khokahano)

1.3 Ho omisa le ho Felisa

• Profiling ea mocheso oa silindara ea mouoane(±1°C mamello)
• Taolo ea tsitsipano(40% ea phokotso ea likheo tsa marang-rang)
• Phetoho e iketsang ea reel(<2mm phoso ea boemo)

2. Melemo ea Setsebi ea PLC Systems

2.1 Mehaho ea Taolo ea Mehaho e Mengata

2.2 Papiso ea Ts'ebetso

2.3 Bokhoni ba ho Kopanya Lintlha

• Modbus/TCPbakeng sa khokahano ea MES/ERP
• 5+ lilemoea polokelo ea data ea tlhahiso
• Litlaleho tsa OEE tse ikemetsengbakeng sa ho latedisa tshebetso

3. Thuto-pale: PLC e Ntlafatsa ka Moloho oa Lipampiri oa Packaging

• Hardware:Siemens S7-1500 PLC
• Liphetho:✓18.7% ea ho boloka matla(¥1.2M/selemo) ✓Sekhahla se theoha(3.2% → 0.8%) ✓65% ea liphetoho tse potlakileng tsa mosebetsi(45min → 16min)

4. Mekhoa ea Bokamoso ho PLC Technology

1. Edge Computing- Ho etsa tlhahlobo ea boleng bo thehiloeng ho AI sebakeng sa heno (<5ms latency)
2. Mafahla a Dijithale- Ts'ebetso ea Virtual e fokotsa linako tsa projeke ka 30%
3. Tlhokomelo ea Remote ea 5G- Litlhahlobo tsa nako ea 'nete bakeng sa bophelo bo botle ba lisebelisoa

Li-PLC li khanna indasteri ea pampiri ho eatlhahiso ea “mabone a tima”. Litlhahiso tsa bohlokoa: ✓ AmohelaIEC 61131-3 e lumellanaLi-platform tsa PLC ✓ Koetlisamechatronics e kopantsoengLitheknishiene tsa PLC ✓ Sireletsa20% bokhoni ba ho boloka I/Obakeng sa likatoloso tse tlang

(Mantsoe a bohlokoa a mohatla o molelele: lenaneo la mochini oa pampiri oa PLC, DCS bakeng sa mabili a pulp, tharollo ea ho etsa pampiri e ikemetseng)

Dikgetho tsa ho itlhophisa

Bakeng sa ho ikakhela ka setotsoana ho:

• Khetho e ikhethileng ea brand PLC(Rockwell, Siemens, Mitsubishi)
• Laola logic bakeng sa mekhoa e itseng(mohlala, taolo ea li-headbox)
• Cybersecurity bakeng sa marang-rang a indasteri

Ntsebise sebaka sa hau sa maikutlo. Lintlha tsa indasteri li bontša89% ea ho amoheloa ha PLCs, empa feela32% e sebelisa ts'ebetso e tsoetseng peleka katleho.
