Heart Beat Message Block
A heartbeat is a message sent to the automation computer which is used to supervise the communication
link between the receiver and the automation computer. A heartbeat can be identified by the reference
number used in the AE header that will always be 0000. How often the heart beat message is sent to the
automation computer is a programmable option in the receiver. (See Section 5.4.3.5.)
A typical heart beat message looks like this:
Example:
<$03><"051997"><$22><"074905"><$22><"01"><$22><"0000"><$22><V-byte><$0D>
