Data from log configuration
How to remove a data from log configuration (last 1 hour).
Thanks in advance.
Depends on type of historian.
If its Basic History, I'd try DeleteRaw via the AdvOPCHDAClient.exe tool (part of standard install). Not sure about name, but it contains HDA.
Tool is not documented, nor easy to use.
2. Browse or enter logid (OBJECT:PROPERTY,LOG)
3. Select interface method (DeleteRaw)
4. Set time filter (absolute or relative)
5. Run operation
Might work, but overhead reduces usability for more than a few logs.
If points are in the future, Basic History and IM History have tools for easy removal. Basic History; use applog operation. IM History; use hsDBMaint tool.
