*1 The write count is not equal to the index value. (Since the maximum write count of the flash ROM has been increased by
the system, the value increments by 1 about every two write operations.)

Description
Stores the progress of writing (transferring) to the parameter memory (flash ROM) in
percentage (0 to 100%). "0" is set when the write (transfer) command is issued.
Stores the index value of write count of the program memory (flash ROM)
present in 32-bit binary. When the index value exceeds 100 thousand times, "FLASH
ROM ERROR" (error code: 1610) occurs. (The index value will continue to be counted
even after it exceeds 100 thousand.)
Description
Stores the usage status of the following debug functions.
0: External input/output forced on/off function
1 to 15: Empty (fixed at 0)
(0: Not used 1: Used)
Description
• If the status of the I/O module changes from that obtained at power-on, the module No.
is stored in the following bit pattern. (If the I/O numbers are set by parameter, the
parameter-set numbers are stored.)

No I/O
verification
When the number of I/O points of the module exceeds 16 points, all bits corresponding to
errors
the I/O module number (in units of 16 points) that is included in the number of I/O points
I/O
occupied by the module turn on.
verification
error exists
Example: When a 64-point module is connected on the slot 0, b0 to b3 are turned on by
error detection.
• Not cleared even if the normal state is restored. This flag is cleared by the error
resetting operation.
