How to timestamp variables included in a report provided by a BMENOP0300 IEC61850 communication module ?

It can generally be updated when its linked variable status change, by one of the following three (3) methods :

1. Automatic Timestamp

• The module automatically assigns the time value(Data Attribute “t”) of the variable based on its internal clock.
• The internal clock can be synchronized with an external time source viaNTP (if enabled) or will use CPU time.

2. Manual Timestamp

• The user manually inserts the time value into theData Attribute “t” of the variable through:
  • The PLC program
  • Device DDT
• In this case, the "t" attribute must be included in the module’s I/O mapping.

3. Using ERT/CRA Timestamp

• Timestamping can be performed via the ERT/CRA module using the SOE function.
• Refer to the BMENOP0300 user manual (page 137) for more details.

Implementation Notes

To useOption 1 (Automatic Timestamp), do NOT include the variable “t” in the server I/O mapping of the module.

Example: Variable AlmTOut

• Only its value stVal is included in the I/O mapping . Not "t".
• It is essential to include the Data Attribute “t” of this variable in the report dataset so that it is updated by the module during report generation.

1. Insert the Data Object “AlmTOut” in the report dataset, by selecting both:
   • t
   • stVal
2. After insertion, the Attribute value will remain empty — this is normal.

• Insert valuestVal is in the I/O mapping , without its "t":

The module will automatically update the variable’s timestamp when its state changes.
