How to configure automatic variable timestamping on the BMENOP0300 module acting as a server

There are generally three ways to integrate the timestamp corresponding to a Data Object (DO) state change:

1. Automatic Timestamping

   • The module automatically updates the timestamp value (Data Attribute "t") within the variable.
   • This is only possible when the "t" attribute is not included in the module I/O Mapping.

2. Manual Timestamping

   • The user manually writes the timestamp value into the Data Attribute "t" through the PLC application and the Device DDT.
   • In this case, the "t" attribute must be included in the module I/O Mapping.

3. ERT Timestamp Module with SOE Functionality

   • Timestamping can be managed through an ERT timestamp module using the Sequence of Events (SOE) feature.
   • Refer to the product documentation for detailed implementation guidelines.

3. In the corresponding report dataset, add the "AlmTOut" Data Object and select both the "stVal" and "t" attributes. Including the t attribute in the dataset is required so that the timestamp is published when a report is generated.

4. After inserting the Data Object with both attributes selected, the Attribute column may appear blank. This is normal and expected behavior:

With this configuration, the module will automatically update the timestamp associated with "AlmTOut" each time its state changes.
