D-24 Instruction Set Quick Reference
SFC Reset
SFR
The SFR instruction resets the logic in a sequential function
chart. When the SFR instruction goes true, the controller
performs a lastscan/postscan on all active steps and actions in
the selected file, and then resets the logic in the SFC on the
next program scan. The chart remains in this reset state until
the SFR instruction goes false.
End of Transition
EOT
The EOT instruction should be the last instruction in a transition
file. If you do not use an EOT instruction, the controller always
evaluates the transition as true.
See page F-8 for a description of prescan operation for
this instruction.
User Interrupt Disable
UID
The UID instruction temporarily disables an interrupt-driven
ladder program (such as an STI or PII) from interrupting the
currently executing program.
User Interrupt Enable
UIE
The UIE instruction re-enables the interrupt-driven ladder
program to interrupt the currently executing ladder program.
