Sync manager channel 3

Sync manager 3 is used for process input data. It contains the Tx

PDOs specified by the PDO assignment object 0x1C13 (hex).

The RECA-01 module provides two watchdogs, with which the

functionality of the module and connection can be monitored. The

watchdogs are configured and enabled by the EtherCAT® master.

The PDI watchdog monitors the module's CPU. Each access from

the CPU to the ESC (EtherCAT® Slave Controller) resets this

watchdog.

The sync manager watchdog monitors the output sync managers.

If the output I/O data is not updated by the master within the

configured time the watchdog will timeout and reduce the state of

the module from OP to SAFEOP. The resolution of this watchdog

is 1 ms.

Note: EtherCAT® by design provides no way for a slave to

monitor the connection to the master if the slave has no output

data.

Note: The drive reaction to a communication fault must be

configured separately. Consult the drive manual for more

information.
