I/O Connections
The I/O Connections diagnostic web page presents a summary of I/O
connections initiated by the module.
Each Class 1 UDP connection has a receive/tr
ansmit (Rcv/Xmt) pair of data
and heartbeat. The originator of a connection listens on the multicast address
to receive the data. The target of the connection receives the heartbeat.
In this example, the Web page is for the module at address 10.88.60.194.
This
module (10.88.60.194) originated a connection to 10.88.60.188 with an RPI of
10.
