Distributed clock technique
Ø All of the IO device has a local clock
Ø Real-time Ethernet communication by automatically and continuously synchronize all other clocks
Ø communications with the time offset can be compensated
Ø The maximum deviation between all the clocks are less than 100 ns
Ø Distributed clock time as the current system time, because it can be used throughout the system.
Timestamp Technology
Ø timestamp data type has a time value of additional transmission
Ø use the system time value is usually time for the process to provide accurate time information data
Ø stamp can be used to record signal input time for the output signal controls the output of the time.
Oversampling
■ oversampling IO board can be achieved in a single scan input value within a time interval of several other samples,
■ The data recorded in an array
■ a scan cycle in all transferred to the controller
■ For the output value to the output change in a scan cycle times
■ oversampling factor describes a communication cycle sampling (changing) the number of
■ In general, under the conditions of the communication cycle time, can easily reach 200 kHz sampling rate.
