jgcramer Posted November 14, 2013 Report Share Posted November 14, 2013 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!

mckruger Posted November 14, 2013 Report Share Posted November 14, 2013 Hi I went to watch this webinar where they show u a demonstration on modbus master and slave using RS232 http://www.unitronic...webinars/modbus This will enable you to read/write data between a master and slave.

swb311 Posted November 14, 2013 Report Share Posted November 14, 2013 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. Link to comment Share on other sites More sharing options...
