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 is a serial bus sys­tem which ori­gi­nally comes from the auto­mo­tive sec­tor. The signals are trans­mit­ted via a twis­ted pair. The inter­fe­rence immu­nity of CAN net­works is par­ti­cu­larly high due to various mea­su­res, such as CRC checks, use of dif­fe­ren­tial signals, etc. CAN descri­bes the phy­si­cal bus con­cept inclu­ding the data link layer. The app­li­ca­tion layer, i.e. the pro­to­col to be used, is not descri­bed by CAN. The­re­fore, a dis­tinc­tion must be made bet­ween CAN (phy­si­cal bus) and CANopen (pro­to­col, app­li­ca­tion layer).

 

 

CANopen

CANopen describes the standardized use of communication services and thus forms a communication profile. For the user, CANopen has the advantage that devices from different manufacturers can be combined in a CAN network. However, differences may occur in the number of communication objects supported. In contrast to PROFIBUS-DP, CANopen has the advantage of true multi-master capability.
