Alert if no answer pollling Gateway

[rivieraautomation]

Hello, 

I have a KNX/Modbus Gateway (intesis one) and I have realised there was no "connectrion" anymore on KNX part of the gateway. 

So I didn't receive any response to some grp.read command. 

After rebooting the gateway everything is now OK, but I would like to control and send alert in case of I lost again connectivity on the KNX part of the Gateway. 

When I lost part, after a grp.read command on a group adress, I don't receive any infomration. 

How can I log this ?? 

Thanks in advance for your help !!
