Stores the self-diagnosed error number in BIN. (Refer
to page 22 for the error codes.)
Stores the step number in BIN, at which an instruction
execution error occurred. After that, data is updated
each time operation error occurs.
Stores the step number in BIN, at which an instruction
error occurred. Since data is stored into D9011 when
M9011 turns from off to on, D9011 data is not updated
unless M9011 is cleared by the user program.
3 (fixed): Both input and output refreshes
Stores the operating status of the PLC function.

Stores the number that indicates which sequence
program is currently in execution.
1 (fixed): Main program (RAM)
Stores the scan time at every END that is smaller than
D9017 data, i.e. stores the minimum scan time in BIN.
Stores and updates the scan time at every END in
BIN.
Stores the scan time at every END that is greater than
D9019 data, i.e. stores the maximum scan time in
BIN.
Special registers for communication with the master
station in CC-Link.
