Micrologix 1200 1500 Osr Instruction

Dua Anjing said:

OSR is ONE SHOT RISING. When it sees a OFF to ON transition then OUTPUT bit will be ON for one scan only. I "think" that storgae bit will remain ON until the input goes OFF, this is how the PLC catches the OFF to ON transition

HI

Reviewing this thread I do not see the difference between OSR ML 1500 and SL OSR instruction. Both final output is on for one scan only except one has storage bit and slc is without it but I am not sure if I am right. Thanks

IF Rung = TRUE then {
IF NOT STORAGE_BIT then {
	 OUTPUT = TRUE
	 STORAGE_BIT := TRUE
}
ELSE OUTPUT := FALSE
}
ELSE STORAGE_BIT := FALSE
