In addition to the usual data fields that you would expect to find on a ClearSCADA Point object, a Totalflow String Point object also has the following data fields, which are listed in the ClearSCADA Database Schema (String Point Schema View). The name in bold at the start of each entry is also the OPC tag name.
- LastError—This field contains a string that describes the last error on the point. For example, a DB2 protocol error for a write request to a read only value.
- LastErrorTime—This field contains the timestamp for the entry in the LastError field. The driver generates the timestamp and as such the timestamp uses the same time zone as the server.
