There is no heartbeat timeout in the P329 but there is a SYNC monitor which will create an error condition if 2 sync messages are missed in a row.

The ‘Heartbeat Producer’ protocol has been implemented. When object 1017_00 is non zero the protocol is enabled with the heartbeat message being transmitted on Cob-ID 700H+Node ID.

‘Heartbeat Consumer’ and ‘Node Guarding’ protocols have not been implemented.

When object 1006_00 is non-zero then SYNC message monitoring is enabled - if 2 consecutive SYNC messages do not arrive within the time specified then the unit will revert to pre-operational mode.
