Details
• The day of the week is stored as BCD code as shown below.
b15 to b12 b11 to b8 b7 to b4 b3
Always set "0"
• Stores the block No. of the extension file register being used in
BCD code.
• Designate the device number for the extension file register for
direct read and write in 2 words at SD1036 and SD1037 in BIN
data.
Use consecutive numbers beginning with R0 of block No. 1 to
designate device numbers.
SD1037,SD1036
Device No. (BIN data)
• Sets priority of ERROR LEDs which illuminate (or flicker) to
indicate errors with error code numbers.
• Configuration of the priority setting areas is as shown below.

• For details, refer to the applicable CPUs User's Manual and the
ACPU Programming manual (Fundamentals).
• Turned on/off with a peripheral device.
When STRA or STRAR instruction 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.
• 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.
• 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
• 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.
• 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.
