#QCH |
0, Protocol, Address, Baudrate |
The command sets the HMI interface parameters for RS485. In addition to the Protocol, the RS485 Address and Baudrate can be configured.

Set HMI LAN parameters
#QCH |
1, Protocol, IP, Subnet, Gateway, Port |
The command sets the HMI interface parameters for LAN. The IP address, Subnet and Gateway as well as the Port can be configured here. IP, subnet and gateway are passed as 32-bit values (e.g. 192.168.5.9 → $C0A80509).

2, Protocol, IP, Subnet, Gateway, Port, "SSID string"; "Password string" |
The command sets the HMI interface parameters for WIFI. The IP address, Subnet and Gateway as well as the Port can be configured here. IP, subnet and gateway are passed as 32-bit values (e.g. 192.168.5.9 → $C0A80509).
The WIFI SSID and password are also defined.

#QWL |
Array-Id (SSID), Array-Id (RSSI), Callback macro |
The command scans for all available WiFi networks, stores the result in two arrays (SSID and RSSI) and calls the callback macro at the end. The signal strength is coded as follows:
