* Heartbeat Instance (Listen Only): Enables monitoring of the input data (output data for TF6280) if a connection exists. The "Listen Only" connection is also terminated when the normal connection is terminated.
** Heartbeat Instance (Input Only): Enables reading of the input data (output data for TF6280). This connection is independent of the actual communication.
The heartbeat is necessary for the monitoring of both connection types (Listen Only and Input Only).
