[etherlab-users] Detect the loss of EtherCAT communication

[Christoph Schroeder]

Hi All,

is there any other way for a slave to detect a failure of EtherCAT
communication besides the syncmanager watchdogs  e.g. connection loss
between 2 slaves or a failure of the user application? The syncmanager
watchdog only works for buffered mode but not for mailbox mode which has
acyclic communication.
Background: our slaves will use mainly mailbox communication (VoE) which
is most suitable for our purpose. We solved this problem by introducing
a status byte as PDO which also has a watchdog configured. I am still
eager to know if there is some other possibility for a slave to detect
missing EtherCAT communication.

Thanks and best regards,
Christoph
