1. Me Yasa Gwajin Wayoyin PROFINET Yake Da Muhimmanci

PROFINET wani tsari ne na Ethernet na masana'antu wanda aka amince da shi sosai wanda ke ba da damar sadarwa ta lokaci-lokaci tsakanin na'urori a cikin yanayin masana'antu. Yayin da ƙungiyoyi ke ƙara dogaro da wannan fasaha don haɓaka haɗin kai da sauƙaƙe hanyoyin aiki, ba za a iya wuce gona da iri ba muhimmancin tabbatar da inganci da aikin kebul na PROFINET. Gwada waɗannan kebul ba kawai matakin kariya ba ne - mataki ne mai mahimmanci wajen kare dukkan kayayyakin more rayuwa na hanyar sadarwa.

Gwada kebul na PROFINET yana tabbatar da manyan fa'idodi guda huɗu:

Sauya kowace kebul da asarar sigina da ta wuce iyakokin da aka saba (misali, >3 dB) don tabbatar da amincin hanyar sadarwa na dogon lokaci.

6. Kurakuran Gwaji da Aka Saba Yi Gujiwa

Kurakuran da aka saba yi waɗanda ke kawo cikas ga daidaiton gwaji sun haɗa da:

Tsallake tabbatar da kariya a cikin yanayin EMI mai ƙarfi.
Dogaro da na'urorin gwaji masu darajar mabukaci maimakon na'urorin da PROFINET ta amince da su.
Yin watsi da jagororin shigarwa na masana'anta.
Rashin gwada kebul a ƙarƙashin ainihin kaya, yana hana gano matsalolin aiki waɗanda ke faruwa ne kawai yayin aiki.

7. Shawarwari Kan Dogon Lokaci Kan Amincewa

Yi amfani da kebul na Cat6 ko mafi girman PROFINET don duk sabbin shigarwa.
Kafa tsarin kariya daga lalacewa ta hanyar gwajin kebul na lokaci-lokaci don gano lalacewar da wuri.
Zaɓi kebul masu jacket na LSZH ko PUR don yanayi mai wahala ko mai wahala.
Ajiye kuma riƙe kebul yadda ya kamata, guje wa lanƙwasawa ko matsin lamba na inji don hana ƙananan fasawa waɗanda ke lalata aikin lantarki akan lokaci.
