ModBus/TCP

[Анна]

Hello! 

We use Codesys to write data in the address range 0x3000...0x5fff to the non-volatile memory of the Wago 750-881 controller. There is a task to read this data from the controller's non-volatile memory using Labview. We have to read this data by ModBus/TCP.

Please tell me how to do this.

Download the NI Modbus library from VI Package Manager.

I would use the LabVIEW Modbus API. You can install it by the use of VI Package Manager.

That is the same library I was suggesting.

Yes, you were quicker than me to type the answer and I discovered yours after sending mine.
