Extension file
registerfor
designation of
device number
Device number when
individual devices
from extension file
register are directly
accessed
• 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.

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

be expansion file register No. 1, is used or if SM320 is OFF.
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

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.
