4.3.2 Browsing variables
For defining the variables to be displayed, »VisiWinNET®« allows you to "browse" variables.
Depending on the bus system and the control system type, there are different file formats available
from which »VisiWinNET®« can take the variable information and offer it for selection.
• In the case of CANopen, this is for instance an EDS file containing the parameters of the
corresponding device.
• This can also be the project file of a control program (e.g. Logic & Motion, CoDeSys, STEP 7®
program), containing the variables of the control.

Tip!
The »VisiWinNET®« project wizard helps you to select the right browser.
Browsing online/offline
With an automation system that is already completely available, some browsers allow you to
browse the system from »VisiWinNET®« (online "browsing").
In practical operation, online "browsing" is rarely used because the system is often not yet complete
and still has to be commissioned.
As an alternative, offline browsing is possible, which requires special device description files that
contain the parameter information of a specific device type. Depending on the control and bus
system, these files differ from each other.
The following chapters describe the way of browsing and the file types that can be used.
