Heartbeat protocol

The heartbeat protocol can be used for node monitoring purposes within a CAN network.

Basic procedure

1.

A heartbeat producer cyclically sends a heartbeat telegram to one or several receivers (consumers).

2.

The consumer(s) monitor(s) the heartbeat telegram for arrival on a regular basis.

The inverter can be configured as producer or as consumer to monitor up to four other nodes.

Parameter

Address	Name / setting range / [default setting]	Information
0x1016:000 (P520.00)	Consumer heartbeat time: Highest sub-index supported (Cons. heartbeat: Highest subindex) – Read only	Highest subindex, permanently set to 4. Corresponds at the same time to the maximum possible number of nodes to be monitored.
0x1016:001 (P520.01)	Consumer heartbeat time: Consumer heartbeat time 1 (Cons. heartbeat: Cons. heartbeat1) 0x00000000 ... [0x00000000] ... 0x00FFFFFF	Node ID and heartbeat time of node 1 which is to be monitored. – Format: 0x00nnhhhh (nn = node ID, hhhh = heartbeat time in [ms])
0x1016:002 (P520.02)	Consumer heartbeat time: Consumer heartbeat time 2 (Cons. heartbeat: Cons. heartbeat2) 0x00000000 ... [0x00000000] ... 0x00FFFFFF	Node ID and heartbeat time of node 2 which is to be monitored. – Format: 0x00nnhhhh (nn = node ID, hhhh = heartbeat time in [ms])
0x1016:003 (P520.03)	Consumer heartbeat time: Consumer heartbeat time 3 (Cons. heartbeat: Cons. heartbeat3) 0x00000000 ... [0x00000000] ... 0x00FFFFFF	Node ID and heartbeat time of node 3 which is to be monitored. – Format: 0x00nnhhhh (nn = node ID, hhhh = heartbeat time in [ms])
0x1016:004 (P520.04)	Consumer heartbeat time: Consumer heartbeat time 4 (Cons. heartbeat: Cons. heartbeat4) 0x00000000 ... [0x00000000] ... 0x00FFFFFF	Node ID and heartbeat time of node 4 which is to be monitored. – Format: 0x00nnhhhh (nn = node ID, hhhh = heartbeat time in [ms])
0x1017 (P522.00)	Producer heartbeat time (Prod. heartbeat) 0 ... [0] ... 65535 ms	Time interval for the transmission of the heartbeat telegram to the consumer(s). – The heartbeat telegram is sent automatically as soon as a time > 0 ms is set. – The set time is internally rounded up to the next multiple of 10 ms.
