NJ-series CPU Unit Software User’s Manual (W501)
The set values for the input response times of the Basic Input Units are output to the following system-
defined variable.
You can restart a Special Unit (Special I/O Unit or CPU Bus Unit) to enable values that are set for it. If
you restart a Special Unit, you do not have to cycle the power supply to the Controller. Execute the fol-
lowing ResetUnit (Restart Unit) instruction to restart Special Units.
If Special Unit settings are changed in any of the following ways, you must restart the Special Unit or
cycle the power supply to the Controller.
