connnect Labview with Din-Messbus (CAN,Profibus..) devices

[xtocox]

hello,


i have an instrument wich is working with the german DIN-Meßbus protocol
(also called measurement bus at DIN 66348). now i want to connect this
device with labview (in use with a PCI-485 card)! is there any labview-driver to connect
DIN-Messbus-devices?


thank you for answering,



regards

Hey xtocox,

National Instruments doesn't have any devices that directly support DIN-Messbus.

If DIN-Messbus is an implementation of CAN then you can use a PCI-CAN device with LabVIEW or if DIN-Messbus uses standard serial RS-485 then you can use NI-VISA to implement your application with LabVIEW.

However, RS-485 and CAN are hardware protocols. If DIN-Messbus uses this hardware protocol then you can use NI's device, but if the DIN-Messbus has its own hardware protocol you can not. Many customers confuse serial and CAN because they both have 9-pin DSUB connectors, but the two devices are not compatible in any way and are not capable of communicating. You will have to check to see what hardware protocol your instrument uses before you can decide what hardw
are to purchase.

I hope this helps out.

hello JoshuaP,

DIN-Meßbus is a protocoll like CAN or Profibus... but it wasn`t offten used in industry, so nobody really has information about this protocol.
the device is connected by a pci-485 (rs-485) card. the rs 485 is only the hardware-connect-protocol, wich supplies the device with demanded voltage levels...
the data-protocoll is a DIN-Meßbus protocoll. this protocoll is partioned in a view levels (layer 1,2 -for standard telegrams, layer 3 -is the userinterface telgram). if you want to see the complete construction of a DIN-Meßbus protocol, please go to: www.measurement-bus.de
What i need is a softwaredevice (for example a labview dll) wich contains this protocol, so i can implement this one or a windows based driver, wich works between labvie
w and the PCI-485 card...

thanx and a nice weekend
