MU-WebdynSun – V1.1
11.
Displaying operating data
The WebdynSun gateway constantly collects data from inverters, smart meters, input/outputs and Modbus
devices. This data set is described in definition files, which provide a link to the application server. The data
values are written periodically after a configurable acquisition period (by default, every 10 minutes), then
uploaded to an FTP server ready for formatting.
It is possible to display this data locally on the home page of the built-in Web server on the gateway, or on an
external Modbus display.
The variables to be displayed are described in the definition file IDsite_REPORT.ini, available on the FTP
server in the directory /DEF/REPORT.
The gateway can display up to a maximum of 10 variables.
Two types of variable may be distinguished:
•
•
Cumulative variables: Power, Energy, etc.
Instantaneous variables: Temperatures, Light levels, etc.
By default, the gateway displays the following variables in HTML format:
- Date/Time of report
- Instantaneous power of the installation
- Total energy produced.
- Daily energy produced.
- CO2 savings.
- Daily CO2 savings.
Four additional variables can be added to the display.

Displaying cumulative variables
Instantaneous power of the installation
The instantaneous power corresponds to the sum of the powers of all the inverters configured on the
gateway. This variable can have different names depending on the manufacturer and the type of inverter. It
is for this reason that a list of variable names is predefined in the gateway to enable it to identify the inverter
variables to be added in. However, it is possible to specify a variable name in the definition file
prefixID_REPORT.ini.
