Define the hardware configuration for the entire system
The window is separated into three areas:
•
Hardware configuration
•
System components
•
Settings (at the bottom; hidden here)
To increase the size of the "Hardware configuration" area, the "System components" and "Settings" ar-
eas can be hidden by clicking the relevant button (right arrow/downward arrow).
Hardware configuration
The "Hardware configuration" area shows the device (in this case the variTRON 300 CPU) and, if appli-
cable, all previously added system components (modules). The view can be enlarged or reduced using
the zoom function ("+" and "-" magnifying glass icons).
Since the variTRON 300 CPU does not have any lateral connections for power supply and system bus,
a router module is required (primary: router module 1 port) to connect further modules. In the setup pro-
gram, this router module must be placed on an additional DIN rail. In a real system, it can be placed on
the same DIN rail as the central processing unit.
In the setup program, the connection between the router module and the central processing unit is es-
tablished in the same way as the connection between router modules (see following description). In the
real system, a commercially available network cable is used (min. CAT5, S/FTP; connection to the LAN2
socket of the central processing unit).
The position of a module on the DIN rail can be changed by dragging and dropping the module accord-
ingly.
