9.7.8.5 Setting and resetting the master structure
The notifications and variables are set by the EtherCAT master stack when the event
occurs. If a notification/variable has been set, it remains set until the master structure is
explicitly reset.
When an error has been eliminated, the notifications/variables must be reset. This can be
done with the following actions:
 Calling the ResetMasterStatus (FB) function block of the SM_EtherCAT.lib function
library (typically used in Logic control systems).
 Calling the SMC_ResetAxisGroup PLCopen function block of the SM_DriveBasic.lib
function library.
 Reset PLC (cold and original)
bEC_NOTIFY_FRAME_
RESPONSE_ERROR
This notification is set when the response frame currently received by the master
does not correspond with the expected frame or when the master has received no
response at all.
bEC_NOTIFY_CYCCMD_
WKC_ERROR
This notification is set if within a cycle the current value of the working counter in
the control/PLC does not correspond with the value read back via the fieldbus. (Not
all of the slaves addressed have reached.)
