Value	Meaning
nCpuId	ID of the TwinCAT CPU core
nActualDelay	The current latency time of the TwinCAT CPU core in µs
nMaximumDelay	The maximum latency time of the TwinCAT CPU core in µs (maximum latency time since the last start-up of the TwinCAT system).
nDelayLimit	Limit value for the alarm for exceeding the latency time of the TwinCAT CPU core in µs
nUsage	The current CPU usage of the TwinCAT CPU core in %
nUsageLimit	The maximum permitted CPU usage of the TwinCAT CPU core in %
