ʻO MODBUS ASCII/RTU kahi protocol kamaʻilio haku-kauā, hiki iā ia ke kākoʻo i nā kauā 247 i hoʻopili ʻia i kahi kaʻa a i ʻole kahi pūnaewele hōkū. Hoʻohana ka protocol i kahi pilina simplex ma kahi laina hoʻokahi. Ma kēia ala, neʻe nā memo kamaʻilio ma ka laina hoʻokahi ma nā ʻaoʻao ʻelua.
ʻO MODBUS TCP kahi ʻano like ʻole o ka ʻohana MODBUS. ʻO ke kikoʻī, uhi ia i ka hoʻohana ʻana i ka memo MODBUS ma kahi "Intranet" a i ʻole "Internet" kaiapuni e hoʻohana ana i ka protocol TCP/IP ma kahi awa paʻa 502.
Hiki i nā memo master-slave ke:

• Heluhelu (Nā helu hana $01, $03, $04): aia ke kamaʻilio ma waena o ka haku a me ke kauā hoʻokahi. Hiki iā ia ke heluhelu i ka ʻike e pili ana i ka counter i nīnau ʻia
