CANopen Fieldbus Cou­pler – HE 5811

CANopen Fieldbus Cou­pler HE 5811

HIMOD is an intel­li­gent I/O sys­tem for all com­mon fieldbus stan­dards. The fieldbus cou­pler HE 5811 with a CAN bus inter­face enables the trans­mis­sion of pro­cess, para­me­ter and con­fi­gu­ra­tion data. The fieldbus con­nec­tion is made on the top of the Bus Cou­pler via a Sub-D con­nec­tor. The serial com­mu­ni­ca­tion inter­face allows simple con­nec­tions to hig­her-level con­trol­lers, visua­liza­tion tools, etc.

Each func­tion module pro­vi­des pro­cess values to the fieldbus cou­pler. The built-in module pro­ces­sor reli­e­ves the fieldbus cou­pler of mea­su­red value cal­cu­la­ti­ons. The inputs and out­puts are mul­ti­func­tional and require a spe­ci­fi­ca­tion. This is stored in the cou­pler and is trans­fer­red when a simi­lar module is repla­ced, even during ope­ra­tion.

In the bus cou­pler, the areas of sup­ply vol­tage, fieldbus and logic are gal­va­ni­cally iso­la­ted from each other. The sys­tem con­fi­gu­ra­tion con­sis­ting of bus cou­pler and I/O modu­les can be quickly deter­mi­ned via the but­ton inte­gra­ted in the front of the housing. Con­fi­gu­ra­tion and para­me­ter­iza­tion of the indi­vi­dual modu­les can be done via the fieldbus as well as via the Smart­Port inter­face.

Up to 16 func­tion modu­les can be con­nec­ted and sup­plied to one bus cou­pler. The sys­tem struc­ture can be exten­ded by using power sup­ply modu­les:

• Up to 62 func­tion modu­les can be addres­sed logi­cally by one bus cou­pler.
• Up to 4 instal­la­tion levels can be set up.
• The maxi­mum exten­sion may be up to 10 m long.

CAN ‘Con­trol­ler Area Net­work’

CAN ist ein seri­el­les Bus­sys­tem, wel­ches ursprüng­lich aus dem Auto­mo­bil­be­reich kommt. Die Signale wer­den über eine ver­drillte Zwei­draht­lei­tung (twis­ted pair) über­tra­gen. Die Stör­si­cher­heit bei CAN-Net­zen ist durch ver­schie­dene Maß­nah­men, wie z.B. CRC-Checks, Ver­wen­dung von dif­fe­ren­ti­el­len Signa­len, etc. beson­ders hoch. CAN beschreibt das phy­si­ka­li­sche Bus­kon­zept inkl. Daten­si­che­rungs­schicht. Die Anwen­dungs­schicht, d.h. das zu ver­wen­dende Pro­to­koll wird durch CAN nicht beschrie­ben. Daher muss zwi­schen CAN (phy­si­ka­li­scher Bus) und CANopen (Pro­to­koll, Anwen­dungs­schicht) unter­schie­den wer­den.
