Basic Modbus Serial Communication

[Heckler511]

Hey Labviewers!

Is there anyone out there who can provide a simple and straighforward plan of attack for getting LabVIEW to communicate with a device via Modbus Serial RTU?  Are there ready made example VIs in LabVIEW that aid in this task?

Any thoughts are appreciated.

Are you using the LabVIEW Modbus library? There have been a lot of discussions over the years about Modbus, a search on "Modbus" will turn up. This one partially addressed the cabling question, looping back, etc., to establish if you have communications.

Modbus has some odd aspects, from configuring the addresses on, but first you have to confirm that the data is getting from one end to the other. We will need to have more data about what your trying to do and where you have gotten to.

Hang in there
