How to troubleshoot FT-10 networks
Solution
Troubleshooting Suggestions:
FT-10 channels are half duplex, so devices have to wait for other devices to stop sending messages before it can send its own message.
Recommend keeping sustained traffic below 40 percent to allow important datapoint messages to be sent when needed.
Use LonScanner 5 Protocol Analzer to verify network traffic (free download)
Allows you to check bandwidth and verify connectivity between devices
CRC error rate should be below 4%
Make sure the FT-10 channel is properly terminated
Free-topology - single terminator typically placed near the network interface or router.
Bus topology - 2 terminators, one at each end of the bus.
