Configuration using the WBM
You configure the gateway parameters in Web Based Management (WBM). The WBM
consists of Web pages stored in the gateway. From a configuration PC you connect to the
WBM of the gateway via HTTPS.
1.3 Configuration examples
Below you will find examples of possible configurations with the "CloudConnect 7" gateway:
Connection of a process stations to a cloud broker
In the configuration shown, the gateway reads process data from one or multiple S7 stations
and transfer the data to a cloud broker or OPC UA client using MQTT.
A Modbus station, such as the programmable controller of a third-party supplier, can also be
connected to a cloud broker for data transmission.
● When it is connected to a SIMATIC S7, the gateway communicates using an S7
connection.
● When it is connected to a Modbus station, the gateway communicates using
Modbus/TCP.
