Details
• When one of F0 to 2047 is turned on by
, the F number, which has been detected earliest among
SET F
the F numbers which have turned on, is stored in BIN code.
• SD62 can be cleared by or
RST F
If another F number has been detected, the clearing of SD62
causes the next number to be stored in SD62.
• When one of F0 to 2047 is turned on by
F number, which has been detected earliest among the F numbers
which have turned on, is stored in BIN code.
• SD62 can be cleared by executing
instruction or moving INDICATOR RESET switch on CPU module
front to ON position.
If another F number has been detected, clearing of SD62 stores
the next F number into SD62.
• The operation status of CPU as shown below are stored in SD203.

*1: When the CPU mdoule is in RUN mode and SM1040 is off, the
CPU module remains in RUN mode if changed to PAUSE
mode.
• Indicates which sequence program is run presently. One value of 0
to B is stored in BIN code.
• If scan time is smaller than the content of SD520, the value is
newly stored at each END. Namely, the minimum value of scan
time is stored into SD520 in BIN code.
• At every END, the scan time is stored in BIN code and always
rewritten.
• If scan time is larger than the content of SD526, the value is newly
stored at each END. Namely, the maximum value of scan time is
stored into SD526 in BIN code.
