PARAMETER REGISTRATION TO CPU
MODULE
C24 enables the parameter settings to be saved in the CPU module.
It reduces man-hours for any recovery works since the parameter resetting is not necessary at the time of replacement of
C24.
The parameters controlled by the CPU module are as shown below.
Parameters name
Module parameter
Module extended parameter
*1 It indicates a file name to store the parameters in CPU built-in memory or SD memory card.
*2 The value indicating the head input/output number of the module  10H (3 digits in hexadecimal) is entered in 'mmm'.
*3 The sequential serial number of each module, 00 is entered in 'nn'.
For more details on parameters controlled by CPU modules, refer to the following manual.
 MELSEC iQ-R CPU Module User's Manual (Application)
The parameters controlled by C24 parameter corresponding to CPU module are as shown below.
Corresponding parameter controlled by
CPU module
Module parameter
Module extended parameter
Each file of module extended parameters held in the CPU module is given priority over the one in the flash ROM of C24.
The contents in flash ROM of C24 is replaced with the contents of module extended parameters registered in the CPU module
by powering OFF  ON or switching the CPU module STOP  RUN after the module extended parameters were registered
in the CPU built-in memory or SD memory card.
Storage location of parameters
CPU built-in memory (data memory)
Select from the following for each file.
• CPU built-in memory (data memory)
• SD memory card installed in the CPU
• Built-in memory of Intelligent function module (in
