modbus error code 6101 and framing error

[jack1]

Using the Vi's MB INIT and MB WR to monitor the registers of a Micro-Motion sensor but keep getting either Framing error 1073807253 or timeout 6101. The communication is RS232, 1 stop bit, RTU (8 data bits), 9600 Baud and the program reads 50 consecutive registers (Floating), timeout is set to 2000 ms. Usually the errors occur after about 5 minutes or so.

Search the forums for 'modbus 6101'. Should find lots of info.

Hello Jack.


Could you attach your VI please?
It should be helpful.

Hello Romain

Please find attached my Vi. I have reduced the amount of registers taht were originally read from 50 down to 20 and increased time delays which seems to have removed the error code problem.

However I still miss data, for example the temperature reading will be fine for a few minutes but then go to zero or a large number. The same thing occurs with other registers that are being read.

Thanks

Jack

Hello Jack.

I find this thread on the forum.
You should have a look on this link too.

There are some forums with the same error. I hope you will find what you want.

Best Regards.
