Extended PEM attributes at run time

The values of extended PEM attributes for which the PEMAttrs.<Instance Name>.<AttributeName>.Log log attribute is set to True are recorded at run time when a PEM command is triggered.

A valid data log group ID must exist for the specified data log group name.

For example, the data log group name for extended PEM attributes is represented as follows:

• OCO_001|Mixing|ProductionData

• OCO_100|Blending|MaterialConsumption

When extended PEM attributes are triggered, the following actions are performed at run time:

• The middleware queries the Data_Log_Value table by using the specified data log group name and the extended PEM attribute name to retrieve the value index.

• The specified extended attribute value is copied in the corresponding value column in the Data_Log table after retrieving the value index.

• This process is repeated for all the specified extended attributes.
