Meaning
Write (transfer)
Stores the progress of writing (transfer) to the program memory (flash ROM) in
status display
percentage (0 to 100%). "0" is set when the write (transfer) command is issued.
(percentage)
Stores the index value of write count to the program memory (flash ROM)
Write count
present in 32-bit binary. When the index value exceeds 100 thousand times, "FLASH
index up to the
ROM ERROR" (error code: 1610) occurs. (The index value will be counted even after it
present
exceeds 100 thousand.)
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 one about every two write operations.)
Meaning
Stores the status of the following debug function.
0: External input/output forced on/off function
1 to 15: Empty (fixed to 0)

(0: Not used, 1: Used)
Meaning
• 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 module numbers are set in parameter,
the parameter-set numbers are stored.)
Bit pattern, in
units of 16
points,
indicating the
modules with
verification
errors
When the number of I/O points of the module exceeds 16 points, all bits corresponding to
0: No error
the I/O module number (in units of 16 points) that is included in the number of I/O points
1: Error
occupied by the module turn on.
Example: When a 64-point module is mounted on the slot 0, b0 to b3 turn on
when an error is detected.
• The values are not cleared even after the system returns to normal. To clear the values,
clear the error.
