Question

Hello there,

According to TRB141 wiki pages, this device can be configured as modbus master/slave via Services → Modbus menu. This menu does not show up on the latest TRB1_R_00.07.01.2 firmware:

How can it be configured as modbus master/slave?

Answer 1

Hello,

From packages available on the menu I assume you are in basic configuration mode, if you switch to advanced by clicking on the word BASIC in the top right corner of WebUI, the MODBUS option should appear.

Thanks for your help.

Is there any way to see the 4-20mA analogue input value in routers web interface?

Yes, it is. The status of I/O pins can be seen in Services -> INPUT/OUTPUT.

You can check out more here: https://wiki.teltonika-networks.com/view/TRB141_Input/Output#Status

To show the pin output in mA, you would need to set pin 7 as an analog current loop. PIN6 is ground PIN7 is positive.

Services-Status page is empty and does not show any information:

Empty input/output status issue is present only in Chrome. Edge shows configuration input/output configuration page correctly, but still does not show Analogue input value after its been configured to Analog Current Loop. Does it require any additional configuration?

Hello again,

There currently is an issues with firmware upgrades to 7.1.2 version with keep settings option enabled, where it does not accurately show I/O statuses. A router reset to factory setting should resolve this issue. You can also take a backup of your configuration before reset, instructions on how to do that can be found here:
