The possible reasons: LabVIEW DSC: (Hex 0X8ABC8FD3) the I/O modbus server cannot connect to the Modbus Ethernet slave device. Whenever I have try t connect following this tutorial OR ( ), I have an error message to my shared variable. These instruments aren't NEITHER, therefore they that I could not directly connected to the device via USB, GPIB or VISA. I'm trying to control instruments connected to this API. I was wondering if someone has never connected this particular PLC before LabVIEW. I have included a link below to a Modbus for LabVIEW library that you can try.Ĭonnect LabVIEW to Schneider Electric M258 Logic Controller (TM258LF42DT4L) error - 1967353901 If this is something you don't have, and purchasing a license is not an option, then you might be able to use Modbus unofficial libraries to get the functionality you need.

The white paper which indicated you using this module, which may explain why you can't get the communication at work. Any help will be greatly appreciated.Ĭommunicate with the PLC via Modbus usually requires the Datalogging and Supervisory Control (DSC) Module to have this feature available in LabVIEW. I read the article on place OR 'connect Labview to any PLC via Modbus', but I don't know yet. Currently I can communicate via Modbus to the API for programming using UnityPro XL, but I have no idea how to connect Labview.

I am eager to serve a Labview HMI to control the controller that is used to implement the control PID with a VFD.

I was wondering if someone could give some tips on how to connect Labview to Modicon Quantum plc (the card is 140 CPU 10 311). How to connect Labview to PLC Modicon Quantum (140 CPU 311 10) with Modbus
