Energy EL72xx EL74xx

The Energy AX72xx EL74xx module is suitable for energy monitoring of EL72xx and EL74xx EtherCAT Terminals. The input data is averaged over a configurable interval and then calculated. To ensure that the required input data is available, it must be added to the process image.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Sample Rate: Sample rate of the system to be analyzed in Hz.
• Rated Current: Nominal current in mA.
