Examples of Possible Sampling Period Settings
The following table shows examples of sampling periods that you can set. The task periods shown be-
low are typical values. Refer to the user’s manual for the connected CPU Unit for information on possi-
ble task period values.
If the sampling period is indicated as "---", it is less than 5 µs and you cannot set I/O allocations.
