s.pratt Posted May 11, 2015 Report Share Posted May 11, 2015 Hello, We have program examples of setting up Modbus Masters and Modbus Slaves in VisiLogic. You can find them through the Help tab. Depending on whether you are using Modbus RTU or Modbus TCP, the folder directories are a little different in the pop-up window that appears after selecting "Eamples..." under the Help tab. Modbus RTU: Version 900> Project Examples> Communications> MODBUS Modbus TCP: Version 900> Project Examples> Communications> Ethernet> Ethernet Modbus IP The files may not be made specifically for the V570, but if you enter into the Hardware Configuration and change the controller model, the application will change over. Also, we have tutorials on our website to help you create Modbus applications. Here is the tutorial on Modbus. Let us know if this helps.
