Why Isn't All of a Tag's Data Visible In the OPC Quick Client?


Last Update: 11/7/2018

Problem:
The value of a tag being read is truncated even though the OPC Quick Client's Value field is set to the maximum value.

Possible Cause:
The OPC Quick Client's Value field is limited to a maximum size of 256 characters: anything after 256 characters will not be displayed. The server and drivers support a variety of data types. Data types that support data exceeding 256 characters include Data Arrays and Strings.

Solution:
Use a client that provides a larger field for viewing the data.
