Tips For Configuration Server Settings - Ceag CG-S / IP-Router + 1P Betriebsanleitung

The command buttons below the list have the following meaning, referring specifically to the selected devices:
Add A further router can be manually entered into the list.
Edit IP address, port. Name and group affiliation can be edited.
Delete The device is deleted from the list, meaning it receives no information via other devices and no
longer participates in the communication.
Test Device status is tested and the test result is displayed above the list.
Static Changes the devices selected to permanently registered devices. This is of interest for devices that
have been added via Automatic Registration during commissioning. These can be then rapidly
changed to static devices for which no de-registration takes place.
Dynamic The device is set to a condition corresponding to Automatic Registration, meaning if it does not
register within the specified Automatic Deregistration Timeout, it is deleted from the list of registered
devices.
Disable The CEA-852 channel communication of the device is temporarily deactivated. The device remains
registered and also shows that it is connected to the configuration server. Use the Static or Dynamic
commands to reactivate it.
Blacklist Registrations from a device with this IP address are no longer accepted.
Recontact The configuration server rejects the device data and reconstructs the list of registered devices with
all data.

4.3 Tips for configuration server settings

Channel Timeout, danger of data loss
The Channel Timeout should be deactivated (= 0). If it is set too briefly, it may cause the loss of data packets. The
precision of time synchronisation between the participating routers is of importance here: if Channel Timeout is for
example less than the possible difference between device times, this will definitely cause data loss.
Multicast addressing, reduction of bus load
If many devices exist in the network, this is the preferred method of addressing as it reduces bus load.
A further possibility for reducing bus load is Time To Live, in this case the definable IP TTL under CEA-852 Device.
This limits the number of routers over which a data packet can be forwarded until its validity expires. Appropriate
values for this can be derived from the network structure (perhaps ask the network administrator) or can be defined
empirically.
Automatic Registration, rapid commissioning
Automatic Registration is the best method to rapidly ascertain all LON/IP devices in the network. With aid of the
commands available under CEA-852 Channel List, the status of the devices can be set to Static, or unwanted de-
vices can be removed from the communication via Disable or Blacklist. Automatic Registration can then be termina-
ted for normal operation.
Disable or Blacklist
In Automatic Registration mode, messages from devices with Blacklist status are no longer accepted. Disabled
devices no longer receive information and can therefore no longer forward messages, but continue to be registered
