Number of slave configurations in the Modbus TCP Master function.

Hello,
I have TRB145 and some number of temperature sensors connected to it over RS485. I want to configure much more sensors later and I found the next sentence in the manual: "You can create a maximum of 10 slave configurations."
https://wiki.teltonika-networks.com/view/TRB145_Modbus#:~:text=You%20can%20create%20a%20maximum%20of%2010%20slave%20configurations
I checked it manually and added more than 10 slave configurations (19) and looks like it works. Does it mean that it allowed working only with 10 Modbus devices and in case if I have for example 30 temperature sensors with different Modbus addresses I cannot use the Modbus TCP Master function? Maybe you could explain how this restriction works and if it still exists?

Best regards
Yuri S.

Hello,

Thank you for contacting .

Yes , you are right the max of 10 TCP masters could be configured but this is for TCP/IP.

For serial Rs485 you can connect up to 32.

Thanks.
