If the synchronous operating mode is activated, but no SYNC0 interrupts are released, the F5-
EtherCAT operator switches in automatic synchronous mode at default setting which can be identi-
fied in the following display string:
Figure 4:
Operator display: Saut0
Herein the operator simulates the SYNC0 interrupts time controlled according to the configured
Sync0 cycle time. In the following the SYNCO interrupt is meant if we speak from ‚
SyNC event
‘.
The SYNC timeout time is four times of the adjusted SYNC cycle time (see Com_Cycle). This can
be adapted by the user via parameter
User_HS_SyncToutTime
.
A process output data monitoring is additionally running to the SYNC monitoring in the current soft-
ware, when the EtherCAT operator runs in synchronous operation mode. The operator recognizes
the missing of incomming new process output data. The value of parameter Real_HS_SyncTout-
Time is accepted as timeout time. That means the PDOUT monitoring operates with the same
Timeout adjustment as the SYNC Timeout monitoring.
However this additional functionality can be switched off for downward compatibility reasons via
parameter FBS Config. In contrast to the reaction to the SYNC timeout case (HS_SyncToutMode),
the reaction to the PDOUT timeout case is not adjustable in the synchronous operation mode. If
the PDOUT timeout case occurs, the operator automatically leaves the synchronous operation
mode and goes into EtherCAT status PreOperational. The SYNC timeout reaction is carried out, if
PDOUT timeout and SYNC timeout occur simultaneously.
