3.4 Ethernet Modbus Jagora Sabis

Bayan serial Modbus, tsarin PSCA na iya amfani da ɗayan tashoshin Ethernet guda biyu na musamman don sabis na Master na Ethernet Modbus TCP/IP. An taƙaita wannan aikin don amfani a kan hanyar sadarwa ta Simplex.

• Kanfigareshan hanyar sadarwa: Adreshin IP na Modbus TCP dole ne ya kasance a wajen kewayon subnet na IONet. Ana saita duk tashoshin Modbus na Ethernet ta hanyar 'Port 7' a cikin ToolboxST.

• Sikeli da Ayyuka: Tsarin PSCA guda ɗaya zai iya tallafawa har zuwa tashoshin Modbus Ethernet guda 18. Nauyin CPU a kowane tasha ya bambanta dangane da adadin rajistar da ake buƙata da ƙimar sabuntawa. Dole ne a inganta abubuwan fitar da bayanai yayin gwajin tsarin lokacin da tashoshi da yawa da/ko manyan kundin bayanai suka shiga.

• Injin Sadarwa: Yana bin ƙayyadaddun Modbus/TCP. Tsarin yana amfani da tsarin sake gwadawa: idan lokacin amsawa ya ƙare (tsoho 1s), yana sake ɗaukar liyafar har sau 6, yana haifar da jimlar ƙayyadaddun lokaci mai inganci sau 6 saitin ƙarewar lokaci ɗaya. Bayan abubuwa uku a jere 'Babu Amsa', tsarin yana rufe haɗin kuma yana ƙoƙarin sake kafa shi lokaci-lokaci.

Wannan yana ba da damar daɗaɗɗen bayanan na'ura don a jujjuya su cikin ƙima mai ma'ana na injiniya waɗanda za'a iya amfani da su ta hanyar dabaru na sarrafawa.

4. Bincike da Kulawa

Samfurin PSCA yana fasalta ingantattun bincike na kai don tabbatar da amincin tsarin:

• Gwajin Ƙarfafa Kai: Ya haɗa da duban RAM, ƙwaƙwalwar filasha, tashoshin Ethernet, da mafi yawan kayan aikin allo.

• Ci gaba da Kulawa: Yana sa ido kan kayan wuta na ciki don aiki daidai.

• Tabbatar da Hardware/Software: Yana bincika ID na lantarki daga allon tasha, allon saye, da allon sarrafa kayan masarufi don saitin kayan masarufi, kuma yana tabbatar da dacewa da lambar aikace-aikacen.

• Babban Bincike: Abubuwan shigar da analog suna goyan bayan tantance iyakokin tsarin daidaitacce. Ana iya kulle duk siginonin bincike daban-daban kuma a sake saita su ta siginar RESET_DIA lokacin da lafiya. Ana samun cikakken bincike a ToolboxST don saurin magance matsala.
