I have a project where I need to use Siemens S7 modbus to control a VFD. More info on the VFD can be found here. https://www.valinonline.com/products/esv113n04txb I'm new to PLC programming and never done anything with modbus. I can program the PLC and make it the master, but I don't know how to program the VFD. So I'm here to see if anyone can guide me on the basic steps on how to set up the connection between the PLC and VFD through modbus. I greatly appreciate any help. |

Hello. Attempting to compliment Mr Chartier's helpful notes, the following addition might be of value. It is an application sample for pairing a drive and an S7-1200 through Modbus RTU. |

VFD programming won't be a big deal. Just follow their commissioning guide and set the relevant parameters as per your requirement. For the communication, there might be only few parameters, not that complicated. Just start with proper installation and wiring and test without load.
