 4.8.- DATALOGGER MODULE: DATA STORAGE 
The CVM-A allows data to be stored under the embedded PowerStudio platform integrated in 
the device.
Stored information can be accessed with a web browser compatible with HTML5 and/or with 
HTTP Requests to the integrated XML server.
Note: Refer to  the “ANNEX A: XML SERVICES“ or the PowerStudio manual for more informa-
tion about the XML server. 
After connecting to an Ethernet network and once an IP address has been assigned, use the 
web browser of a computer in the same local network and enter the IP address in the browser’s 
navigation bar.  The embedded PowerStudio environment of the CVM-A can be used to display 
the data in real time, as well as the data stored over time.   
Refer to the PowerStudio manuals and tutorials on CIRCUTOR’s website for more information 
about additional congurations, sending emails, generation of additional calculations, etc.
