Sequence Output Instructions Section 3-3
Description When the execution condition is ON, OUTB(534) turns ON bit N of word D.
When the execution condition is OFF, OUTB(534) turns OFF bit N of word D.
If the immediate refreshing version is not used, the status of the execution
condition (power flow) is written to the specified bit in I/O memory. If the imme-
diate refreshing version is used, the status of the execution condition (power
flow) is written to the CPU Unit’s output terminal as well as the output bit in I/O
memory.
Flags There are no flags affected by this instruction.
Precautions Immediate refreshing (!OUTB(534)) can be specified. An immediate refresh
instruction updates the status of the output terminal just after the instruction is
executed on an output bit allocated to a CPU Unit built-in output, at the same
time as it writes the status of the execution condition (power flow) to the spec-
ified output bit in I/O memory.
When OUTB(534) is programmed between IL(002) and ILC(003), the speci-
fied bit will be turned OFF if the program section is interlocked. (This is the
same as an OUT instruction in an interlocked program section.)
When a word is specified for the bit number (N), only bits 00 to 03 of N are
used. For example, if N contains FFFA hex, OUTB(534) will control bit 10 of
word D.
