BiSS Serial Protocol

[WoutHuff]

Hey,

I know this is a old post, but I feel obliged to respond.

I'm working with the cRIO system and I'm reading sensor data from a Renishaw absolute encoder with the BiSS Protocol.

To do communicate to the sensor I'm using NI9401 Digital I/O.

I'm considering to switch to sbRIO.

If people are still interested in how I got it working on the FPGA, let me know.

Hello, 

I am dealing with a problem that it seems you already solved. 

I have cRio system, Renishaw linear absolute encoder and iC-Haus BiSS interface.

How can i use the three to get data from the sensor?

(I dont mind using BiSS connected directly to my PC) 

at the moment, it seems as if labview 2017 doesnt recognize that BiSS interface.

Hello,

to get to your to the my solution, first a note: I'm not using the iC-Hause BiSS interface.

I'm using the NI9401 DI/O module.

I will post a snipped of my code.

the BiSS interface for the Renishaw absolute encoder is unidirectional.

to communicate you have to sent a clock signal on MA.

than you have to Read out the SO and catch the data according to the data sheet.

the next note you have to make your data lines differential, I'm using the adm4855 IC

Thank you for your post.

I'm not an electrical engineer so I would appreciate you would elaborate your explanation.

what do you mean by SO, MA etc.

it would be great if you kindly upload your VI as a starting point for me to fit to the BiSS

iC Haus has labview-API which i can use, but i'm not sure about the sequence nor they explain on their manual.

Have fun!

Thank you!

Hi,

  I am using a Bogen absolute encoder with an iC Haus Biss-C interface. Were you able to establish communication with your Renishaw encoder with Labview and the iC-Haus interface? Thank you in advance for your time.
