Remarks
Program
control 128 Subroutine call
If the input is ON, the instruction calls the subroutine for
the subroutine number nn.
2~3 92
129 Subroutine return Indicates the end of the subroutine. 1 73
130 Conditional jump
If the input is ON, jumps directly to the label for the label
number nn.
2~3 67
136 Jump label Indicates the jump destination for the conditional jump. 2 40
132 FOR-NEXT loop
Executes the section from FOR to NEXT the number of
times specified by n.
2 90
133 NEXT NEXT loop 1 55
137 Subroutine entry Indicates the entrance to the subroutine (number nn). 2 40
138 STOP Stops the program 1
140 Enable interrupt Enables execution of the interrupt program. 1 41
141 Disable interrupt Disables execution of the interrupt program. 1 61
142 Interrupt program end Indicates the end of the interrupt program. 1 41
143 Watchdog timer reset Extends the scan time over detection time 2 68
144 Step sequence initialize
Turns OFF the n devices headed
by device (A), and turns (A) ON
(activation of step sequence).
These comprise
one step
sequence.
3 124
145 Step sequence input
Turns output ON when input is
ON and device (A) is ON.
2 97
146 Step sequence output
When input is ON, the instruction
turns OFF the devices with step
sequence input instructions on the
same route, and turns device (A)
ON.
2 70
241 SFC initialize
When input is changed from OFF to ON, the instruction
resets the n steps from the SFC step (A), and activates
step (A) (activation of SFC).
