connect plc using modbus with labview

[unclebump]

Use portmon to capture the serial data stream that is being transmitted and post that info.

The link to the modbus library is still valid and you can simply download them yourself.

p.s. It's not a good idea to include your email address in a message or have it as your user name. Do you like spam?

Hello Faizi,

What type of issues are you running into trying to communicate with your PLC? If you could give us more details, we might be able to help you.

Regards,

Ryan

Hi Ryan

problem is that plc is not responding,i don't know if i have to program my plc, how to identify the address of input pins of plc to labview and how to make a ladder digram which will identify labview data.IF a sensor is attatched to plc x0 how would plc will send it's data to labview and how would labview will acknowledge that data has come from x0

I can't speak much for programming the PLC itself, but I can recommend the best ways to communicate with a PLC from LabVIEW. The general process requires the use of an OPC Server which you can use to communicate with your PLC via standard OPC communication. I recommend taking a took at the article linked below if you want to know more in detail though.
