An ASCII register for Modbus in OPC server?

[esafete]

I am supposed to read and write a (6) register Ascii command in modbus protocol between my pc and a micromotion flow meter transmitter.(Model RFT9739)

I am using Lookout modbus OPC server but it does not have an ASCII option (as opposed to an integer, floating-point, or bit).

Anybody know how I can read and write ASCII strings in labview through Modbus Protocol.

Typically, you would write the decimal ASCII codes to the corresponding integer register. To convert from an ASCII character to an ASCII code, refer to the KnowledgeBase "How can I Convert ASCII characters to ASCII codes and Vice-Versa?". This can be found by searching on "ascii" from www.ni.com.
