28SV11T MODBUS

[johnsuo]

Hello everyone,

I want to control and monitoring my project that is working with delta plc (28SV11T). this plc support serial MODBUS but I can't connect to it with labview. I monitoring it communication to WPLSoft (software to program this plc) and think that comunication with this is unique.

How can connect to this?

Thanks

Best regards,

Shali

Please provide more details other than 'can't connect'. There are several ways to use modbus in LabVIEW. Which are you using? Do you get an error? If so, what is it?

I'm sorry for low details question?

I using MODBUS Library for LabVIEW and Connect LabVIEW to Any PLC With Modbus.

The first ones's error is Time-out error and second one is communication failure.

I think to connect with this plc we must sending special order of dialogs. Is it possible?
