ModBUS communication with EX9024D (ADAM-4024)

Recommended Posts

Hello!

I have a next project where I have to use module EX9024D. 
For this project I use Unitronics Samba (SM43-J-T20) with v100-17-rs4 module (because this combo is what I have right now).
Operation manual for EX9024D: https://www.expertdaq.com/media/downloads/ex-9021_ex-9022_ex-9024.pdf

Basically I have to send  #023-02.500 command to module (page 20). This command will generate -2.5V to output 3 (total 4 outputs, 0-3).

This task is little over my head, especially when it comes to using ModBUS, so I will need help.

How do I transmit this kind of command over ModBUS (I believe I also have to transmit character #, not sure tho)?
Could anybody please explain and guide me through this?

I have also tried to watch provided example files, but this is still too confusing to me.

Best regards,
Steven

Hello Steven

A quick scan through the manual  tells me that this communication is not modbus but serial over RS 485.

For this kind of communication you have to get familiar with the FB protocol.

With this protocol you can build your serial Messages.

On the Unitronics website you can watch webinars about using FB protocol.

 

Hope it helps.

Kind regards

Oh dang!
Asked seller specifically that does this module has modbus (as ADAM-4024 has), and he confirmed that it has modbus.
Looks like I have to start learning FB protocol then. :lol:

Would be great though, if someone has example or anything like that. :rolleyes:
 

EDIT: I think I have figured this one out on my own, finally.
