2.4.2 Digital output
Functions
The following function can be assigned to the digital output:
• Switching output for remote control via the interface
The digital output is remotely controlled via the integral communication interface. The
Modbus function codes can be found in chapter Modbus (Page 79).
• Energy pulse output, programmable for active energy pulses or reactive energy pulses
The digital output issues the parameterized number of pulses per energy unit (e.g. kWh).
