Even if "0" is set, errors which cause
CPU operation to stop (including
parameter settings) are unconditionally
displayed on the LED display.
Default values: D9038=H4321
D9039=H0765
!
When M9044 is turned ON/OFF by the peripheral device to activate the STRA or
STRAR sampling trace instruction, the value stored in D9044 is used as a
sampling trace condition.
Scan - 0
Time - Time (10ms increments)
!
Stores the block No. of the extended file registers used as an SFC work area.
Upper 8 bits ............ Block No. is stored.
Lower 8 bits ............. Step number is stored.
!
Stores in BIN the error number which occurred in the SFC program.
0 : No error
80 : SFC program parameter error
81 : Simultaneously executed step count excess
82 : Block starting error
83 : SFC program operation error
!
Stores in BIN the block number where error occurred in the SFC program.
Note that if error 82 occurred, the start source block number is stored.
! Stores in BIN the step number where error 83 occurred in the SFC program.
When error 80 or 81 occurred, "0" is stored.
When error 82 occurred, the block starting step number is stored.
!
Stores in BIN the transition condition number where error 83 occurred in the SFC
program.
When error 80, 81 or 82 occurred, "0" is stored.
!
Stores in BIN the transition condition or operation output sequence step number
where error 83 occurred in the SFC program.
!
Stores in BIN the step number which was being executed when status latch was
executed.
! Used when making a self-loopback check.
!
Stores the number of free request registration areas for communication with the
MNET/MINI(-S3). (Max. 32 areas)
! Stores the time check value for execution of the link instruction (ZNRD, ZNWR)
for MELSECNET/10.
!
Setting range : 1 to 65535s
! Setting increments : 1s
!
When the setting is 0, operation is performed with the default value of 10s.
!
Stores in BIN the value found by dividing the "first I/O number of the last
registered special function module" by 16 when the number of registerable special
function modules is exceeded.
!
Stores in BIN the detail error number at self-diagnosis occurrence.
!
Stores in BIN the upper two digits of the first I/O number of the I/O module
dismounted/mounted online. Example: Input module X2F0→H2F
