Modbus RTU
Modbus RTU ndi njira yolumikizirana yotsatizana yozikidwa pa mawonekedwe a hardware a RS‑485.
Imagwiritsa ntchito ma binary coding kuti igwire bwino ntchito.
Ma baud rates wamba: 9600, 19200, 38400, 57600, 115200 bps.
Kapangidwe ka akapolo ambuye: mbuye mmodzi, akapolo angapo.
Mtunda wolumikizirana: mpaka mamita 1200 (ndi RS‑485 repeater).
Ntchito zodziwika bwino: zida zakumunda, masensa, ma PLC, mita yoyezera, mita yoyendera.
Ubwino:
Ma waya osavuta, mtengo wotsika
Yokhazikika m'malo opangira mafakitale
Amathandizidwa kwambiri ndi zida zamafakitale
Zoyipa:
Mtunda waufupi wolumikizirana
Liwiro lotsika poyerekeza ndi Ethernet
Sikoyenera makina akuluakulu a netiweki
Modbus TCP
Modbus TCP ndi protocol ya Modbus yochokera ku Ethernet yomwe imayendetsa TCP/IP.
Imagwiritsa ntchito mawonekedwe okhazikika a Ethernet (RJ45).
Kulankhulana kudzera pa doko lokhazikika la TCP: 502.
Liwiro lapamwamba, mtunda wautali, komanso wotheka kukulitsidwa kudzera mu ma switch/routers.
Ikhoza kulumikiza zipangizo zambiri pa netiweki.
Ubwino:
Liwiro la kulankhulana kwambiri
Mtunda wautali wotumizira
Zosavuta kuphatikiza ndi SCADA, DCS, ndi makompyuta apamwamba
Yoyenera kuyang'aniridwa kwakukulu komanso patali
Zoyipa:
Mtengo wapamwamba wa zida
Imafuna kasinthidwe ka netiweki (IP, subnet, gateway)
Chidule cha Kuyerekeza
Modbus RTU: Serial (RS485), mtunda waufupi, mtengo wotsika, wogwiritsidwa ntchito kwambiri mu zida zakumunda.
Modbus TCP: Ethernet, liwiro lalikulu, mtunda wautali, wogwiritsidwa ntchito m'maukonde amakampani ndi makina apamwamba.
