DSC-Modbus IO Server

[Jalpa]

 

My application deals with reading registers from a Modbus RTU(serial) target so for the same iv configured a Modbus IO Server which is available in DSC8.6. Appln communicates well between Real-Time Target & LabVIEW on the development PC but doesnot work on a PC which doesnt have LV. Have included RTE8.6 in the installer. Im not using any other DSC features like Security, Logging or Alarming so have not installed DSC Run-Time System on the target PC.

Waiting for response..........

Thanks in advance

Hi Jalpa,

Since you are using the Modbus I/O server from the DSC module, you will probably need the DSC run-time as well.

If you are not using any other DSC feature then you could try using the Modbus library and then try configuring the server.

Hello Denver,

I tried installing the NI Modbus 1.1 from the link that you had forwarded, but failed to install it as its not supported to work on 8.6. Its available only for 7.1 & 8.2.

Have any other solution???....

Tried re-installing the NI modbus library n found its VI in the function palette. Using these VI's I created an application to read registers from the Modbus slave. The application worked on both, the development PC & on the target PC which did not have labVIEW in it, jus had to install the NI VISA drivers.

Thanx Denver
