4 Operation
Once selected, a module can be removed using the "Recycle bin" button or by pressing the Delete key
on the keyboard (you can select the module by clicking on it; you can also navigate using the left/right
arrow keys on the keyboard).
You can use the "+" button to add additional DIN rails. You can switch between the DIN rails using the
Up/Down arrow keys on the keyboard. Empty DIN rails can be removed again using the "X" button.
With the "Bus Scan" button, the system bus of the connected device is scanned and the hardware con-
figuration is read into the setup project.
System components
The "System components" area lists all available system components (open the drop-down menu by
clicking on it). A distinction is made here between the CPU and the modules (controller, relay, analog IO
units, digital IO units, router units). A module can be added to the hardware configuration by dragging
and dropping it or by double-clicking on the module (the CPU is specified by the setup program when
creating a new project).
NOTE!
A maximum of 8 modules can be connected (router modules do not count).
Settings
The "Settings" area displays information on the system component that is currently selected and enables
certain settings to be configured:
•
Product group number (non-editable)
• Designation (button): Opens a window for entering a designation for the system component (in sev-
eral languages)
• Module label: Tag name for the system component (editable; can no longer be changed once the
hardware configuration has been applied)
• Expansion slot (dependent on the module): For selecting the option (open the drop-down menu by
clicking on it)
• Optional module (alias device address):  chapter 4.3.5 "Optional module (alias device address)",

NOTE!
If the hardware configuration is created with the "Bus scan" function, the setting of the rotary coding
switches in the setup project must be checked in the case of a router module 3-port (705042). If neces-
sary, the setting must be changed before the configuration is sent to the device.
Router units
If the hardware configuration contains router units (router modules), these units must be connected with
one another. To do so, proceed as follows (also applies analogously to the connection between the
variTRON 300 CPU and the router module):
1. Click on a router module.
The free RJ45 sockets are depicted by a green border.
2. Double-click on a free socket (or on the "Start connection" connector icon on the right next to the
socket).
On the router module on the other DIN rail, suitable free sockets are depicted by a flashing green
border. A distinction is automatically made here between inputs (Bus In) and outputs (Bus Out).
Please note: To cancel, click on the "Delete connection" x icon on the right next to the socket.
