Each meter has a set of associated status parameters. Parameters for Meter Transaction 00 end in M0, parameters for Meter Transaction 01 end in M1 and so on.
Use the Export Glossary feature, or the Export Modbus Register definitions feature on the Export tab to get details of the enumerations. Do not rely on the values shown here, including registers, here because the enumeration and register number may change for the specific version of the application that you are using.
The Current Trans values hold information for the current transaction that is underway, if a transaction is underway. When a transaction is complete, the Current Trans values are moved to the Last Trans values and then the Current Trans values are cleared. The Last Trans values are guaranteed to be updated before the Transaction Register is set, so the Last Trans values should be used for data logging.
