I have chosen TCP Keep-Alive transport type on the Modbus Data Source and connected to device.
When I track the network packages, I do not see "TCP Keep Alive" packet on wireshark. Even if I enabled and disabled the Data Source for many times during tracking, I could not see the TCP Keep Alive packets.
So, I would like to be sure that my Mango Instance (v3.7.7) is sending TCP Keep Alive packages.
Is there any suggestion how to test it?
Is that a bug at v37.7.?
Thanks in advance,
