hex convert to decimal

• Hi, Im trying to read DYN-200 torque sensor. My value from the read buffer is quite weird it show 2D30 2E30 302D 302E

How are you communicating with this sensor? Which Modbus library are you using? You might want to share the code so that we can understand better.

Hi, i dont have the code..

but this sensor got three kind of communication mode.Im currently doing the mode 0 which will provide torque and speed value.

mode 2 only provide torque value

i will send the picture.

I am new to labview. For mode 0 need to use modbus library? 

[ZYOng]

Based on the screenshots of the user manual you shared, Mode 0 of HEXactive upload protocol is meant for the upper machine designed by the company. 

Since you mentioned that you don't have any code, I guess you are using the NI-VISA Interactive Panel right now. NI-VISA sends and reads the data in the ASCII format, thus you should use the Mode 2 of ASCII Active Upload Protocol instead. In page 6 of the manual, it states that:

A piece of its data format such as: 2B 30 2E 30 30 30 31 0D

This aligns with what you are seeing currently.

So you get a raw string of six bytes, which consists of three 16bit values. The first is toque (U16), the second is speed (I16) and the third is a checksum. Once you can read these size bytes into LabVIEW, the rest is trivial.

So for mode 0, im not able to use NI-VISA to read the value?

For mode 2, it only sends torque value. I test it out and is able to receive the torque value.

I uses VISA-Ni to read but get random value

You need to be significantly more specific.

thanks for replying me, I planned to use modbus
