GetFeatureStatus
Gets the current state of a feature from a device.
Syntax
KsError GetFeatureStatus(
KsFeature Feature,
double* Status
);
Parameters
Feature: specifies which feature to check if enabled or disabled. See the KsFeature type.
Status: pointer to an int value that will be filled in if the feature is enabled or disabled. If the value is one, the feature is enabled, if zero the feature is disabled.
Return value
If the function succeeds, it returns errNoError
, otherwise an error code. For more information about the error code, see the KsError list.
Usable EtherCAT states
ecatOffline, ecatInit, ecatBoot, ecatPreOP, ecatSafeOP, ecatOP
