Power Register Map
This register map contains parameters that are used to store and calculate the power output and input of the harmonic filter. Note that some parameters shown below may not exist in the parameter database/ or shown in PQVision. These parameters have been reserved for future use and are enabled in EtherNet/IP EDS File.
Note:
All parameters with an asterisk (*) in the description will require the Tech level access codes parameter key A: 0x007D (125) and parameter key B: 0xEA6E (60014). All parameters are enabled for communication to EtherNet/IP unless explicitly stated otherwise in the Notes Column of the Table.
