Configuring the Modbus Function

Measures for data security during activated Modbus interface

If you activate the Modbus interface, there is a risk that unauthorized users may access and manipulate the data or devices in your PV system.

To ensure data security, take appropriate protective measures such as:

1. Set up a firewall.
2. Close unnecessary network ports.
3. Only enable remote access via VPN tunnel.
4. Do not set up port forwarding at the communication port in use.
