thank you for your quick reply
You seem to have misunderstood my question.
RUT955 will be in a truck. The connection between RUT955 and the server (RMS) can be temporarily transmitted.
An external temperature sensor will be connected to RUT955 via RS485 (modbus rtu).
We need RUT955 to store temperature data when there is no connection to the server (RMS). When the connection is restored, to send the archived temperature data to the server.
1) Please tell me, if RUT955 will poll one temperature sensor via RS485 (modbus rtu), how long can it store data (RUT955) in its memory?
2) If you use FMB640 as a gateway, and connect a temperature sensor (4-20mA) to the analog input,
Can RMS download historical temperature data when the connection between RMS and FMB640 is restored?
Can RMS show downloaded historical temperature data as a tabular report?
