We reading data over Modbus RTU and pushing the data over MQTT to the platform. the set schedule for data transmission is every 5 minutes but we have noticed that the data is not reaching the broker as per the schedule and sometimes there is a delay for 10 minuted in each transmission.

Is there a way to monitor the connection status and the data transmission on the gateway level to check the issue where is the data getting stucked.

Make sure that the period between reading the data, and sending the data is the same. The period for reading the data can be specified in the Services → Modbus → Modbus Serial Master → MODBUS SLAVE DEVICE CONFIGURATION:

And the period for sending the data can be specified by navigating to Services → Data to Server and editing the created instance:

It should be kept in mind, that the values can be cached in the Modbus database, so the reading interval could be 5 seconds, and the sending period could be 60 seconds. This way all of the data collected in those 60 seconds will be sent at once.

Let me know if this helps!


Best regards,
