Parameter Settings

Before starting, we need to set some system parameters for the gateway. Please refer to the following content for configuration:

Historical Database Settings​

The gateway provides the function of writing historical data to InfluxDB. Through simple configuration, all tag data's historical records and alarm records can be saved to InfluxDB for storage. The specific configuration is as follows:
