CC-Bindings
The following CC-bindings are available:
CCDataOpi: getDpIoRangeConfiguration()
CCDataOpi: getDpIoRangeValid()
CCDataOpi: getDpIoRangeInInformation()
CCDataOpi: getDpIoRangeOutInformation()
CCDataOpi: getDpIoRangeInState()
CCDataOpi: getDpIoRangeOutState()
CCDataOpi: getDataFromDpIoRangeIn()
CCDataOpi: putDataToDpIoRangeOut()

for the compile cycle), it is notified by means of the return-enumerator
CCDATASTATUS_RANGE_NOT_AVAILABLE.
NOTICE
The compile cycle programmer himself is responsible for the correct use of the
CC-bindings! It must be noted that the additional performance requirement needed for
providing the data of the configured I/O-ranges at the Servo-task level, does not lead
to a Servo-level computing time overflow.
See the OEM documents for more information about the use of these bindings.
