Hello everyone.  
Is it possible to tell if a ModBus Node is correctly connected without performing a modbus request?

Let me explain: every 15 min I perform modbus requests to read and record X registers.  
If by chance the network drops for any reason, no modbus node warns me that the connection has dropped, but rather the node stays connected until a request is made and only then does it realize it is disconnected.  
I would like the node to check its status constantly to be ready every 15 min and not lose the data to be acquired.

Thank you, can anyone help me?

You could use a ping node to routinely check network connection.
