We want to get data from a flowmeter connected to a TRB145 only twice in a day. This is to preserve flowmeter battery by reducing number of modbus commands hitting it from TRB145. If we set the modbus command frequency at 43200 seconds (12 hours) and the data to server frequency at 60 seconds or anything less than modbus command frequency, we do not receive the data on the server.
Is there an upper limit to modbus command frequency?
How can we get the data to server only twice in a day?
