Automatic reconnection of MODBUS TCP

[doc_d]

Hi there! 

I have a plc which communicates using Modbus TCP IP with my Lab view code. 

I want to develop my code such that the reconnection happens automatically whenever I remove my ethernet cable and connect again.

Hi,

I was suggesting putting a VISA close function and wire your module ports reference to it before closing the ModBUS communication.

Continuously check for error. If there is no error then pass the modbus reference. If there is any error disconnect the reference and create new reference as below image.
