Instruction Description

SFR

SFC Reset

Prog File Number 3

Restart Step At

SFC Reset	The SFR instruction resets the logic in a sequential function
SFR	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.

(	EOT	)	End of Transition	The EOT instruction should be the last instruction in a transition
			EOT	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.
(	UID	)	User Interrupt Disable	The UID instruction temporarily disables an interrupt-driven
			UID	ladder program (such as an STI or PII) from interrupting the
				currently executing program.
(	UIE	)	User Interrupt Enable	The UIE instruction re-enables the interrupt-driven ladder
			UIE	program to interrupt the currently executing ladder program.
