The e.manager provides a Modbus TCP and RTU interface for reading out data and for controlling power reduction and the cos phi setpoint.

Modbus TCP

The measured values of the individual inverters or devices can also be queried. This is an overview of the possible measured values. Not all registers necessarily contain valid values.

Invalid value: 0xFFFFFFFF

The device ID can be displayed in the e.manager (Maintenance => Configuration files).

Configuration

 

The Modbus RTU or TCP interface is not activated by default.

To activate a Modbus interface, go to "Configuration" => "Device search", select "Modbus Slave" for the relevant interface and click "Search". A Modbus interface is then created immediately. It becomes available after a restart.

Under "Configuration" => "Maintenance" you can change the RS485 ID or the IP address. Please contact the hotline before making changes there for the first time.

e.g. set IP to 192.168.178.33

e.g. set port to 503

bus_id=192.168.178.33
par2=503
