UDP Functionality
Overview
The UDP tab configures the I/O UDP broadcast settings. The I/O UDP broadcast feature periodically
broadcasts the I/O channel status in a UDP message.
You can configure up to four sets of IP address entries (each entry consisting of a start and end IP
address range) to broadcast I/O status data. The broadcast frequency of the UDP packets to the
configured UDP IP addresses can be defined to accommodate network traffic and monitoring PC
application requirements. For details of the UDP I/O datagram see
I/O UDP .
