Hi, I'm having trouble reading the values from the input registers.
I'm using a B&B Spectre 3g Modem www.bb-elec.com/Products/Wireless-Cellul...r-Wi-Fi-Routers.aspx
with the MODBUS-TCP2RTU to read the analog inputs but havent been able to make it work.

The analog input is the 1044. I normally read the value using a 4x1044 or 401044.

Any ideas how I can do this?

Hello Raul,

Do you have a connection to the modbus device? If yes you would have a notification on your android device.
Do you check RTU via TCP(UDP) checkbox in Connection settings of your modbus server in TeslaModbusSCADA?

Hi, I'm finally connected to the device and reading the register's values.
This is what was wrong.

I had the RTU via TCP(UDP) option enabled and also noticed that there's an offset in the addresses. Where the address on the routers manual and at a computer software is 1044, at the testlamodbusscada is 1043.
Don't know if theres a way to configure this offset on the app. I tried at the server's options (Servers->TAP Server Name) but noticed that when I change the offset it resets to 0. Don't know if thats the right way to do it, I'm just guessing.

Hello,
You have to change offset when you bind point to the graphical objects. In this way it woldn't resets.
