zvigadzirwa

2.5 Mamiriro Pane zvimwe zvipimo uye akati wandei sarudzo dzinofanirwa kutariswa mukuronga kuisirwa kwako. 2.5.1 Kuganhurirwa Kwemuviri Muchikumbiro cheEPLCG chisina basa, mamodules epuraimari uye echipiri EPLCG anowanzo kukwira muraki imwe chete, asi haagoni kuwanikwa mune imwechete dual node module. Iwo anowanzo kuisirwa padhuze kune mumwe nemumwe nekuda kwe interlink kana relay panel tambo kureba zvirambidzo. Kana system yako ichishandisa interlink tambo, kureba kwayo kunogadziriswa pamamita matatu. Alternate cable urefu haupo. Kana sisitimu yako ichishandisa relay panel, iyo yakajairwa tambo kureba kune yechipiri EPLCG ndeye 2m, asi imwe tambo kureba iripo. Nekudaro, kana yakarebesa relay panel tambo ikashandiswa, iyo mari inowedzerwa kune relay panel tambo inofanirwa kubviswa kubva kune imwe neimwe yePort 1 uye Port 2 tambo. Zviripachena, kureba kweinotsiva relay panel tambo inofanirwa kunge isingasviki 15 metres (50 tsoka). 2.5.2 Single vs. Multidrop Cabling Panofanira kunge paine tambo imwe chete kubva pachiteshi kuenda kuPLC, modem, kana nhare yekufambisa iyo chiteshi ndeche kusevhisi. Kana iwe uchida kushandisa Modbus protocol multidrop kurongeka, unofanirwa kuisa modem yemuno paEPLCG ine mamodemu ari kure akabatana kune yega yega PLC mune network. Allen-Bradley (AB) protocol multidrop marongero anogara achibatana kuburikidza neAllenBradley communications controller (a CIM, yeCommunication Interface Module). Sezvo uyu wekutaurirana controller achipa iyo multidrop yekubatanidza, chete tambo imwe chete inodiwa kubva paEPLCG port kuenda kune AB controller. 2.5.3 Kureba Kwetambo Matambo anobva pachiteshi cheEPLCG haakwanise kureba kupfuura tambo-mamita gumi neshanu (tambo-tsoka makumi mashanu). Kana chinhambwe kuenda kuPLC kana mutongi wezvekutaurirana akadarika uyu muganho, unofanirwa kushandisa mapfupi-haul modem. Ona chikamu 2.6 chekutarisa modem. EPLCG Planning, Installation, and Service2-10 5/01 2.5.4 2.5.4 Direct Connection Kana uri kubatanidza PLC imwe chete (kana AB communications controller) kune imwe yezviteshi uye kureba kwetambo kubva kuEPLCG kusvika kuPLC isingasviki 15 cable-metres, unogona kushandisa EIA-232 mode direction (EIA-232 mode). Mugadziriro iyi, tambo yeEIA-232 yakapihwa naHoneywell inofanirwa kunge yakasungirirwa kune chinongedzo chinosanganisa PLC yako. Zvikamu 3.2.7 uye 3.2.8 zvinoratidza tambo wiring zvirongwa zvemarudzi akati wandei ePLC uye zvishandiso zvemashandisirwo. 2.6 EPLCG KUTI PLC CONNECTIONS 2.6.1 Kushandiswa kweModemu uye Kusarudza Yakananga-kubatanidza, mamodemu mapfupi (dzimwe nguva anonzi mutsara-mutyairi), kana zvishandiso zvinoshandura masaini zvinogona kushandiswa neEPLCG. Sezvambotaurwa, kubatana-kwakananga kunogumira kune inokwana gumi neshanu tambo-mamita pakati peEPLCI I/O kana Relay kadhi. Signal converters zvishandiso zvinoshandura masiginecha pakati peEIA-232 neEIA-422 kana -485, uye anowanzo shandiswa kupa chinhambwe chakareba kana multidrop masisitimu. Modem-pfupi-haul inopa EIA-232 hardware interface kune EPLCG kana PLC yakafanana neiyo inounzwa neyakajairwa mafoni modem. Iyo modem-haul-haul, zvisinei, inoshandisa mitsara yakatsaurirwa (kwete mitsara yefoni) uye inogona kutora rusununguko neiyo interface protocol isingagamuchirwe mune yakajairwa nhare modem kutaurirana. Mamodemu enhare echinyakare haawanzo shandiswa neEPLCG nekuti anodzikamisa bandwidth, uye iwo anodiwa akaderera kumhanya (baud rate) anogona kukanganisa EPLCG kuita. Iyo EPLCG zvakare haitsigire masaini ekubata maoko anowanzo kudiwa kumamodemu, anosanganisira Chikumbiro-Kutumira (RTS), Bvisa-Kutumira (CTS), Carrier Detect (CD), Data Set Ready (DSR), uye Data Terminal Ready (DTR). Zvigadzirwa zvakasiyana-siyana uye tambo zvigadziriso zvinogoneka. Bvunza nenyanzvi yekutaurirana kana vatengesi vemidziyo uye cabling inoenderana nechikumbiro chako.
