3. Click on a free socket on the other router module (or on the "Close connection" connector icon on
the right next to the socket).
The connection between the two sockets is established (color change).
Please note: To delete the connection, click on the "Delete connection" x icon on the right next to one
of the two sockets (or remove a router module)
4. If necessary, establish connections to other router modules (connections are depicted by different
colors for the relevant RJ45 sockets).

Optional module (alias device address)
Basic differences between the mandatory module and optional module
Mandatory module:
•
The module must be available.
•
The position of the module must correspond to the hardware arrangement in the setup program.
Optional module:
•
Only router modules can be configured as the head module of an HC group (hot connect group or
optional module group) (assignment of an alias device address).
•
The router module and the components of its HC group (optional modules) need not be available.
•
All input/output modules connected to it are also optional modules.
•
Router modules connected to it are optional modules.
•
Due to the alias device address, a router module is always uniquely identifiable within the system.
•
The router module can be defined in the setup program with a fixed or a variable position on the sys-
tem bus.
Differences at system start and during operation
System start:
•
If a mandatory module causes a problem (module defective or not available, wrong position), the
system will not start.
•
The HC group must be completely available or completely missing. If only part of the HC group is
available, the system will not start.
During operation:
•
If a mandatory module fails or is removed, the entire system goes into the "Stop" state.
•
If an optional module is used, the system continues to run.
•
The HC group can be removed from the system and also connected again (hot connect functional-
ity). If a part of the HC group is removed, the remaining modules of this HC group continue to run.
