Question

Hi,

Does the RUT955 have the capability to store data on the SD card and then forward it to the remote server after communication has been restored?

We are monitoring remote pump stations and need to know the dam levels and pump status for the time that we lost communication.

Similiar to what the TRN250 can do?.

Hello,

You could use a feature like MQTT Gateway with the use of commands like the ones showed on the following wiki page (mosquitto_pub, mosquittto_sub), to obtain the data from the MODBUS interfaces on the RUT955’s CLI.

A script that saves those outputs on the SD card file when you lose connection could be created with the help of commands like the following.
