Concept of setup
The main setup channel of the device is the web interface. It is recommended to use it, even more of
the settings are available through SNMP and HTTP API commands.
The device setup begins with network settings.
Then the so-called primary parameters (MODBUS RTU sensors/registers, analog inputs, and digital
inputs) are set up.
The channels are formed from already set up primary parameters. Every channel can combine up to
two primary parameters and constants with math operations. It is possible that a channel is formed by
only one primary parameter.
Once all channels have been tuned, the alarm can be set up. It is important to remember that alarms
work with channels, not with primary parameters. Each alarm can have up to two conditions. Different
channels may be involved in the conditions. Alarms are independent of the channels but can also be
assigned to a channel.
In other words, the right setup should follow the following order:
Once everything above is set correctly, the wanted services (data logger, SNMP, HTTP API, etc.) can be
turned on.

The pages “Data” and “Alarms” are refreshed automatically on at interval of 0 to 253 seconds. Zero
means no automatic refresh. This parameter is set in section “Setup-System- Refresh of channels
and alarms pages”. By default, the refresh interval is 1 second.
