Modbus RTU
ʻO Modbus RTU kahi protocol kamaʻilio serial e pili ana i ka interface lako RS-485.
Hoʻohana ia i ke code binary no ka hana kiʻekiʻe.
Nā helu baud maʻamau: 9600, 19200, 38400, 57600, 115200 bps.
Hoʻolālā haku-kauwā: hoʻokahi haku, he nui nā kauā.
Ka mamao o ke kamaʻilio ʻana: a hiki i 1200 mika (me ka RS‑485 repeater).
Nā mea hoʻohana maʻamau: nā mea hana kahua, nā mea ʻike, nā PLC, nā mika pae, nā mika kahe.
Nā Pōmaikaʻi:
Uea maʻalahi, kumukūʻai haʻahaʻa
Paʻa i nā wahi kahua ʻoihana
Kākoʻo nui ʻia e nā mea hana ʻoihana
Nā hemahema:
Ka mamao kamaʻilio pōkole
Haʻahaʻa ka wikiwiki i hoʻohālikelike ʻia me Ethernet
ʻAʻole kūpono no nā ʻōnaehana pūnaewele nui
Modbus TCP
ʻO Modbus TCP kahi protocol Modbus i hoʻokumu ʻia ma Ethernet e holo ana ma luna o TCP/IP.
Hoʻohana i ka pilina Ethernet (RJ45) maʻamau.
Kamaʻilio ma o ke awa TCP maʻamau: 502.
ʻO ka wikiwiki kiʻekiʻe, kahi mamao loa, a hiki ke hoʻonui ʻia ma o nā kuapo/routers.
Hiki ke hoʻohui i nā polokalamu he nui ma luna o kahi pūnaewele.
Nā Pōmaikaʻi:
Ka wikiwiki o ke kamaʻilio ʻana
Ka mamao hoʻoili lōʻihi
Maʻalahi e hoʻohui me SCADA, DCS, a me nā kamepiula luna
Kūpono no ka nānā nui ʻana a me ka nānā mamao
Nā hemahema:
ʻOi aku ke kumukūʻai lako
Pono ka hoʻonohonoho pūnaewele (IP, subnet, gateway)
Hōʻuluʻulu Manaʻo Hoʻohālikelike
Modbus RTU: Serial (RS485), mamao pōkole, kumukūʻai haʻahaʻa, hoʻohana nui ʻia i nā mea kani kahua.
Modbus TCP: Ethernet, wikiwiki kiʻekiʻe, mamao loa, hoʻohana ʻia i nā pūnaewele ʻoihana a me nā ʻōnaehana kiʻekiʻe.
