Question

Hi.

I'm triying to get the analog value using the Modbus TCP 142 register, but it give me a wrong data:

The correct value is the one I get from the I/O Status page, in this case 5V:

I can get the correct value sendig usind "General" configuration as an "Action" but in this case I only can send it if it goes in or out the range (just one time if it goes in or goes out, not continuosly)

How can I get this analog data continuosly out?

Hello,

Thank you for provided information. It seems to possible firmware issue, could you please connect to the router via SSH and try the following command:

 - ubus call ioman.adc.adc0 status

And see what answer will you get.

Please let me know.

Hello,

The answer for the command is:

root@Teltonika-RUT955:~# ubus call ioman.adc.adc0 status                                                           

{                                                                                                                  

        "value": "2.01"                                                                                            

}                                                                                                                  

root@Teltonika-RUT955:~# 

But I still got "0" when I try to get the value from the Modbus address 142:

And the analog value in the I/O is also correct:

Hello,

Is the value from SSH window is correct? If so, then it means that there is an issue with the firmware version and thus needs to be forwarded to RnD department.

Hi.

Yes, the value is correct. In the mean time, waiting for the firmware update, is any other way to get the analog data continuouly? The I/O juggler just let me get the data once, when it goes in or out the defined range.

I tested the new firmware and it works ok.

Please let me know when will be this update officially realesed for use it.

I have noticed that it may have generated an incompatibility with the Modbus Serial Master module that I am using with other Modbus slaves.

It was up and running but it stops after I made the upgrade. Even once I disabled the Modbus TCP slave

Hello,

Thank you for the feedback.

Please try resetting device to default settings, and check if issue persist. Keep in mind to download MODBUS Serial Master package from the package manager which can be found in Services -> Package Manger.
