Push On/Push Off Circuit (PONOFF) (IB-300)
Push On/Push Off Circuit toggles an output state whenever its input power flow transitions
from off to on. Requires an extra bit parameter for scan-to-scan state information. This extra
230
bit must NOT be used anywhere else in the program. This is also known as a "flip-flop
240
circuit".

PONOFF Parameters
• Discrete Input: specifies the input that will
DS5 Used
toggle the specified output
N/A
HPP
• Discrete Output: specifies the output that
will be "turned on/off " or toggled
• Internal State: specifies a work bit that is
used by the instruction
Discrete Input . . . . X,Y,C,S,T,CT,GX,GY,SP,B,PB
Discrete Output . . . . . . . . . . . . . . X,Y,C,GX,GY,B
Internal State . . . . . . . . . . . . . . . . . . . . . . . X, Y, C
PONOFF Example
In the following example, the PONOFF instruction is used to control the on and off states of
the output C20 with a single input C10. When C10 is pressed once, C20 turns on. When
C10 is pressed again, C20 turns off. C100 is an internal bit used by the instruction.
No permissive contact or input logic is
used with this instruction
NOTE: Neither a permissive nor input logic is used with this instruction.
