Configuration of optional modules
When creating a project with the setup program (hardware arrangement), all modules are initially man-
datory modules. To form a line with optional modules (HC group), the relevant (upstream) router module
must be configured as an optional module:
•
Router module 2-port (705041)
The "Optional" parameter must be set to TRUE (red) in the setup program.
The alias device address is fixed (0x200). Within a system, only a single router module 2-port can
be configured as an optional module.
Connected router modules are then also automatically optional modules (they do not have to be con-
figured as optional modules themselves).
• Router module 3-port (705042)
The rotary coding switches on the module must be used to set an alias device address (address not
equal to 0). The same address must be set in the setup program using the parameters with the same
name (rotary coding switch 10x, rotary coding switch 1x). If the settings do not match, the router mod-
ule is not recognized on the system bus.
Note: if the alias device address 0 is set in the setup program, the address set on the router module
is irrelevant (the addresses are not compared). The router module is then a mandatory module.
The alias device address is freely selectable, but must be unique within the system.
All input/output modules connected to the router module and any additional router modules are then
also optional modules.
The router module as an optional module can also be operated at a system bus output that is not
defined in the hardware arrangement. To prevent this possibility, the parameter "Fixed position" must
be set to TRUE (red). Then the connection is only possible at the specific RJ45 socket of the specific
router module as it corresponds to the hardware arrangement.
• Router module 1-port (705043)
The "Optional" parameter must be set to TRUE (red) in the setup program.
The alias device address is fixed (0x100). Within a system, only a single router module 1-port can
be configured as an optional module.
All input/output modules connected to the router module are then also optional modules.
The router module as an optional module can also be operated at a system bus output that is not
defined in the hardware arrangement. To prevent this possibility, the parameter "Fixed position" must
be set to TRUE (red). Then the connection is only possible at the specific RJ45 socket of the specific
router module as it corresponds to the hardware arrangement.
