Precautions for Correct Use Precautions for Correct Use
High-speed interrupt function improves execution of interrupt tasks under certain restrictions. Be
sure to check the conditions for which use is possible before attempting operation. In particular,
operation can be performed with the minimum time interval for scheduled interrupts set to 0.1 ms
only on the condition that Support Software (e.g., the CX-Programmer) or an NS-series Pro-
grammable Terminal is not directly connected to the peripheral port (USB) or serial port on the
CPU Unit. If a direction connection is made, operation may not be performed at a time interval of
0.1 ms. If Support Software must be connected directly to the CPU Unit for maintenance of other
reasons, confirm that equipment will not be affected if the schedule interrupt is not executed for a
time interval of 0.1 ms before making the connection.
