Intshayelelo kwiModbus RTU kunye neModbus TCP

I-Modbus RTU
I-Modbus RTU yiprotokholi yonxibelelwano olulandelelanayo olusekelwe kwi-interface yehardware ye-RS‑485.
Isebenzisa i-binary coding ukuze isebenze kakuhle.
Amazinga ebhawudi aqhelekileyo: 9600, 19200, 38400, 57600, 115200 bps.
Uyilo lwekhoboka eliyiNkosi: inkosi enye, amakhoboka amaninzi.
Umgama wonxibelelwano: ukuya kuthi ga kwi-1200 yeemitha (kunye ne-RS‑485 repeater).
Izicelo eziqhelekileyo: izixhobo zasentsimini, ii-sensors, ii-PLC, iimitha zamanqanaba, iimitha zokuhamba.
Iingenelo:
Ucingo olulula, ixabiso eliphantsi
Izinzile kwiindawo zoshishino
Ixhaswa kakhulu zizixhobo zoshishino
Iingxaki:
Umgama omfutshane wonxibelelwano
Isantya esiphantsi xa sithelekiswa ne-Ethernet
Ayifanelekanga kwiinkqubo zenethiwekhi ezinkulu

I-Modbus TCP
I-Modbus TCP yiprotocol ye-Modbus esekelwe kwi-Ethernet esebenza phezu kwe-TCP/IP.
Isebenzisa ujongano oluqhelekileyo lwe-Ethernet (RJ45).
Unxibelelwano nge-port ye-TCP eqhelekileyo: 502.
Isantya esiphezulu, umgama omde, kwaye inokwandiswa ngeeswitshi/ii-routers.
Ingaqhagamshela izixhobo ezininzi ngenethiwekhi.
Iingenelo:
Isantya esiphezulu sonxibelelwano
Umgama omde wokudluliselwa
Kulula ukuyidibanisa ne-SCADA, i-DCS, kunye neekhompyutha eziphezulu
Ifanelekile ukubekwa esweni okukhulu nokukude
Iingxaki:
Ixabiso eliphezulu lehardware
Ifuna uqwalaselo lwenethiwekhi (i-IP, i-subnet, isango)
Isishwankathelo sokuthelekisa
I-Modbus RTU: I-Serial (RS485), umgama omfutshane, ixabiso eliphantsi, isetyenziswa kakhulu kwizixhobo zasentsimini.
I-Modbus TCP: I-Ethernet, isantya esiphezulu, umgama omde, isetyenziswa kwiinethiwekhi zoshishino nakwiinkqubo eziphezulu.
