Ina kore e tukuna ngā raraunga ine o te mita rere ultrasonic ki te pūnaha whakahaere matua, ka puta pea te raruraru i roto i te taura hononga. Ka taea te whakatau i te raruraru mai i ngā āhuatanga e 4 e whai ake nei:
Hipanga 1: Tirohia te hononga taura whakawhitiwhiti. Tuatahi, whakaūtia mēnā kua mono pūmau te taura whakawhitiwhiti (pērā i ngā raina RS485 me ngā taura whatunga) i waenganui i te mita rere me te pūnaha whakahaere matua, ā, mēnā he wetekina, he waikura rānei ngā atanga. Mēnā ka whakamahia te whakawhitiwhiti RS485, tirohia mēnā kei te hono whakamuri ngā raina A me B. Mā te hononga whakamuri ka kore e taea te tuku raraunga, nō reira me hono anō ngā waea i te raupapa tika; mēnā ka whakamahia te whakawhitiwhiti Ethernet, tirohia mēnā kei te ora tonu te taura whatunga, ka taea te whakamātautau mā te whakakapi i te taura whatunga. I taua wā anō, whakaūtia mēnā kei te mahi noa ngā taputapu whatunga pēnei i ngā pana me ngā pouara, ā, mēnā kei te ngoikore te hiko, kei te momotu rānei te whatunga.
Hipanga 2: Whakaūtia kei te ōrite ngā tautuhinga tawhā whakawhitiwhiti kōrero. Tomo ki te atanga "tautuhinga whakawhitiwhiti kōrero" o te mita rere, tirohia ngā tawhā pēnei i te tere o te pao, te ōritetanga, ngā moka raraunga me ngā moka mutu, ā, kia tino ōrite ki ngā tawhā whakawhitiwhiti kōrero o te pūnaha whakahaere matua. Hei tauira, ki te whakatakotoria te tere o te pao o te mita rere ki te 9600, ā, ki te whakatakotoria te pūnaha whakahaere matua ki te 4800, ka puta he tuku raraunga rerekē, ā, me whakarite ngā tawhā o ngā mea e rua ki te uara kotahi. I taua wā anō, tirohia mēnā kei roto te wāhitau taputapu (pēnei i te wāhitau pononga) o te mita rere i te awhe mōhiotanga o te pūnaha whakahaere matua kia kore ai e taupatupatu te wāhitau, e puta rānei i waho o te awhe.
Hipanga 3: Whakatauhia te raruraru o te pareārai me ngā tautuhinga pūmanawa. Mena ka whakamahia e te pūnaha whakahaere matua te pūmanawa rorohiko hei whiwhi raraunga, tirohia mēnā ka āraia e te pareārai rorohiko te tauranga whakawhitiwhiti o te mita rere. Ka taea te whakaweto i te pareārai mō te wā poto hei whakamātautau. Mena ka taea te tukuake i ngā raraunga i te tikanga noa, me tāpiri he ture whakaaetanga mō tēnei tauranga ki te pareārai. I taua wā anō, tirohia mēnā kua tīpakohia e te pūmanawa whakahaere matua te kawa whakawhitiwhiti tika (pēnei i te Modbus RTU, Modbus TCP). Ki te kore e ōrite ngā kawa, ka rahua te tātari raraunga, nō reira me tīpako anō te kawa e rite ana ki te mita rere.
Hipanga 4: Whakamātauria te whakawhitiwhiti motuhake o ngā taputapu. Mena he noa ngā mahi o runga ake nei, ka taea te hono tika i te mita rere ki te rorohiko (me te kore e haere mā te pūnaha whakahaere matua), ā, ka taea te whakamahi i te pūmanawa whakamātautau tautoko o te taputapu hei tuku raraunga hei tirotiro mena ka taea e te rorohiko te whiwhi. Mena ka taea te whiwhi, he tohu tēnei kāore he raruraru o te mita rere tonu, ā, kei roto pea i te taputapu, i te pūmanawa rānei o te pūnaha whakahaere matua te hapa, nō reira me rapu raruraru te waeine whakawhitiwhiti me te pūmanawa kohikohi raraunga o te pūnaha whakahaere matua; ki te kore e taea te whiwhi, tera pea kua pakaru te waeine whakawhitiwhiti o te mita rere, ā, me whakapā atu ki te kaihanga mō te tiaki, te whakakapi rānei i te waeine.
