Zomwe zili zofunika kwambiri ndi izi:  Phazi lophatikizika lomwe limathandizira kuyika njanji ya 32 kapena 35 mm DIN  Mtundu wosiyana wa gulu la mabanja  Kutha kwa magawo atatu a RS-422 ndi RS-485 ndi zolumikizira zingwe zinayi za DB-25 zamalo olumikizirana a RS-232  Kusintha kwa ma siginecha a RS kuti musankhe ma siginolo a 2 ndi kulandira ma 2 Kusintha-kusankha kuthetsa resistors kwa RS-422 ndi RS-485 kulankhulana. Mwachidule ma siginecha a Field I/O amalumikizana ndi kagawo kakang'ono ka FBM kudzera pa DIN rail mounted termination assemblies (TAs). Msonkhano uliwonse wa FBM224 woyimitsa (onani Chithunzi 1) ndi chingwe choyimitsa chomwe chikugwirizana nacho chimapereka kulumikizidwa ku miyezo ya mawonekedwe amagetsi (RS-232, RS-422 kapena RS-485) pakati pa zida zam'munda ndi FBM224 Modbus Communication Interface Module. TA ili ndi zolumikizira zingwe zinayi za DB-25 zolumikizirana ndi RS-232 ndikusintha kuti zigwirizane ndi pinout ya RS-232 ya zolumikizira za DB-25 ku zida zosiyanasiyana za akapolo. TA ili ndi mtundu woponderezedwa wa magawo atatu kapena kulumikizana kwa mphete ya RS-422 ndi RS-485 yolumikizirana. Zoletsa zosinthira zosinthika zimamangidwa mu TA kuti zithetsedwe zikagwiritsidwa ntchito ndi RS-422 ndi RS-485 zolumikizirana. Ma TA akupezeka muzinthu za Polyamide (PA). Ma TA okwera njanji ya DIN amalumikiza Modular Baseplate pogwiritsa ntchito chingwe chochotsa. Chingwecho chimapezeka muutali wosiyanasiyana, mpaka mamita 5 (mamita 16), kulola kuti TA ikhazikike mumpanda kapena mpanda wapafupi. ZOCHITIKA ZOCHITIKA PAMODWERO WA Modbus Communications INTERFACE Madoko anayi olumikizirana a I/O amapereka mawonekedwe mpaka mabasi anayi a Modbus (RS-232, RS-422 ndi/kapena RS-485). Madoko 1 ndi 2, ndi/kapena Madoko 3 ndi 4 amatha kusinthidwa ndi ogwiritsa ntchito kuti azigwira ntchito ngati doko limodzi lomveka lokhala ndi zingwe zosagwiritsidwa ntchito pazida ziwiri. BUS CHARACTERISTICS General Electronic Industrial Association (EIA) RS232, RS-422 kapena RS-485 mauthenga osankhidwa pa doko lililonse. Njira yolumikizirana ndi thupi ya RS-485 imakhala ndi chingwe chamkuwa chopindika chokhala ndi kondakitala imodzi. RS-422 ndi njira yolumikizirana ndi mawaya anayi. Njira yolankhulirana yakuthupi ya RS-232 ndi chingwe cha DB-25 kupita ku chipangizo choperekedwa ndi kasitomala. EIA RS-232, RS-422 ndi RS-485 I/O Communication Type Asynchronous communication, direct connect link (RS-232) Transmission Rate 300, 600, 1200, 2400, 4800, 9600, 19,200, 38,001, 201, 200, 200, 200, 200, 200, 200, 200, 200, 38, 200, 70, 401 ba Protocol Modbus protocol mu RTU mode. zilembo 8-bit; osamvetseka, ngakhale osafanana, 1 kapena 2 kuyimitsa pang'ono. Kuthekera kwa I/O Kufikira zida 64 pamlingo uliwonse wa FBM224 (chiwerengero cha zida zenizeni zimadalira magwiridwe antchito) zolumikizana ndi ma point 2000 a DCI.
