Modbus TCP/IP V570 (Example)

[jgcramer]

Hello,

 

Whe are working on a project to use the V570 within a self service bays carwash. This is working great! But now whe wanne go a step further with this project.

 

But whe dont have the knowledge to implementate a Modbus to the V570 to read and write data to it.

 

So my question is of anyone have a working modbus/TCP example? So i can connect to the V570 to read and write data over this connection.

 

Thank you!

Hi

I went to watch this webinar where they show u a demonstration on modbus master and slave using RS232

This will enable you to read/write data between a master and slave.

Thank you! See if its compatible with ethernet.

It is fairly simple.  Connect your sockets, scan on the slave device and poll on the master device.  As usual with Modbus, to talk to many devices you will have to convert your MBs to integers using the BIT->INT FB.

Can also make use of UniCAN.
