5.2.11 Specifying valid parameters (Parameter-valid drive setting)
The parameter-valid drive setting function specifies the drive (memory) in which
parameters to be valid are stored.
The method for specifying the parameter-valid drive differs depending on the CPU
module.
(1) High Performance model QCPU, Process CPU and Redundant CPU
Specify the drive with the DIP switches of the CPU module. ( QCPU User's
Manual (Hardware Design, Maintenance and Inspection)
(a) Parameter-valid drive specification method
Specify a parameter-valid drive in the setting of the DIP switches (SW2, SW3) on
the CPU module.
(b) Valid parameter determination timing
The valid parameters are determined at the following timing.
• When the programmable controller is powered ON (at power ON)
• When the reset operation of the CPU module is performed (at reset)
The CPU module validates the parameters in the drive specified by SW2 and
SW3 at the timing above, and operates using the valid parameters.
