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