DNP3 master and slave unsolicited message issue


Thread Starter


My application is SCADA application used in Gas industry.

We are using DNP3 protocol to send the message between Master and Slave.

My slave has to send the data to Master outstations. But the currently slave is not sending the data to Master. Once the connection is established it is working for some time (1 or 2 days) after that slave stop sending the data.

If I disconnect and connect the outstation, it started working for sometime.

Can you please anyone can help me to resolve this issue, or provide your valuable suggestion to resolve this issue.
