D9044 SD1044
For sampling
trace
Step or time during
sampling trace
• Turned on/off with a peripheral device.
When or is executed, the value stored in
SD1044 is used as the sampling trace condition.
At scanning--------0
At time--------------Time (10 msec unit)
The value is stored into SD1044 in BIN code.
QnA
D9049 SD1049
Work area for
SFC
Block number of
extension file register
• Stores the block number of the expansion file register which is
used as the work area for the execution of a SFC program in a
binary value.
• Stores "0" if an empty area of 16K bytes or smaller, which cannot
be expansion file register No. 1, is used or if SM320 is OFF.
QnA
D9050 SD1050
SFC program
error number
Error code generated
by SFC program
• Stores error code of errors occurred in the SFC program in BIN
code.
0 : No error
80: SFC program parameter error
81: SFC code error
82: Number of steps of simultaneous execution exceeded
83: Block start error
84: SFC program operation error
QnA
D9051 SD1051 Error block
Block number where
error occurred
• Stores the block number in which an error occurred in the SFC
program in BIN code.
In the case of error 83 the starting block number is stored.
QnA
D9052 SD1052 Error step
Step number where
error occurred
• Stores the step number, where error code 84 occurred in an SFC
program, in BIN value.
• Stores "0" when error code 80, 81 or 82 occurred.
• Stores the block stating step number when error code 83 occurs.
QnA
D9053 SD1053 Error transition
Transition condition
number where error
occurred
• Stores the transition condition number, where error code 84
occurred in an SFC program, in BIN value.
Stores "0" when error code 80, 81, 82 or 83 occurred.
QnA
D9054 SD1054
Error sequence
step
Sequence step
number where error
occurred
• Stores the sequence step number of transfer condition and
operation output in which error 84 occurred in the SFC program in
BIN code.
QnA
D9055 SD1055 SD812
Status latch
execution step
number
Status latch step
• Stores the step number when status latch is executed.
• Stores the step number in a binary value if status latch is executed
in a main sequence program.
• Stores the block number and the step number if status latch is
executed in a SFC program.
QnA
D9060 SD1060 SD392

Software version of
internal software
• Stores the software version of the internal system in ASCII code.
Note: The software version of the initial system may differ from the
version indicated by the version information printed on the rear
of the case.
