9-4 Heart Beat
The TRP-C32S provides a convenient way to establish reliable communications between two
devices. Communication port 5300 is reserved for the Heartbeat Protocol. Without this feature a
device that loses a connection and stops communicating would not be able to reconnect without
personally attending to the problem. A TCP data connection can be lost when there is a power
failure or temporary loss of an Ethernet connection on either the client or server.
If a loss occurs the Heart Beat feature will try to reconnect the TCP data connection every 5
seconds until communications is established again. The Heart Beat feature is available to use
with the Virtual COM Mode, Paired Mode and Direct IP Mode. This is not available when using a
UDP application.
