Troubleshooting the IzoT Router
Following are some common problems and recommended solutions.
- Pressing the IzoT Router Service/Connect button does not result in a Service message.
If you are using OpenLDV, do not use Unicode characters that cannot be represented as alphanumeric ASCII characters for the IzoT Network Service LonTalk/IP interfaces name.
Make sure UDP port 2541 is open on your computer’s firewall. - A device based on a Series 6000 chip, CPM 4200 Wi-Fi module, or the IzoT Device Stack EX doesn’t appear in the IzoT Router Device Browser Web page.
Press the device's Connect or Service button or send a service message from the device application. There will be a delay while the IzoT Server discovers the device and adds it to the device list. Sending a service message can accelerate device discovery. - Using 192.168.x.x IP addresses require special handling. IP addresses in the 192.168.x.x range are mapped to the ISO/IEC 14908-1 zero-length domain.
The LonTalk/IP protocol maps 192.168.x.x addresses to the LonTalk zero length domain. If you are using a network management tool that specifies addresses as LonTalk address, you must configure the tool to use the zero-length domain to use IP addresses in the 192.169.x.x range. For example, the IzoT Net Server and IzoT Commissioning tool require network addresses to be specified as LonTalk addresses, with a LonTalk domain, subnet, and node ID. The IzoT Commissioning Tool does not have an interface to specify the zero-length domain, but you can change the network do use the zero-length domain using the OpenLNS Object Browser tool included with the IzoT Net Server. To do this, follow these steps:- Create the network using the IzoT Commissioning Tool using any domain.
- Temporarily close the tool.
- Start the OpenLNS Object Browser from the Echelon IzoT Network Services Utilities start menu and click OK to dismiss the start dialog using the defaults.
- Press F8 to allow modifications, then expand the object view by double-clicking ObjectServer, then Networks, and open the newly created network by double-clicking its name.
- Double-click Systems and the System object underneath (which shares the name of your network).
- In the property pane on the right, double-click the DomainId property, clear the value shown in the New value field, and then click OK. This configures the network into the zero-length domain.
- Close the OpenLNS Object Browser.
- Re-open the IzoT Commissioning Tool.
- Proceed with network configuration and management.
If you are using the IzoT Server, set the domainid property in the IzoT Server $IZOT/etc/lonbridge/config.xml file to use the zero-length domain with the following parameter:
<domainid "0, 0 0 0">
- Create the network using the IzoT Commissioning Tool using any domain.
Check how much free space you have using ssh.
Enter the following command at the console prompt: df- Sometimes large log files or multiple archived files will use up the available flash memory.
