PONOFF - Push On / Push Off
Each time the input logic for a Push On / Push Off (PONOFF) instruction transitions from OFF to ON, the Push On / Push Off instruction will invert the designated bit location. This function is also known as a Toggle output coil. The instruction can be configured with an optional, external Reset location.
Parameters:
Note: Use the F9 key or click the 'three dot box' at the right edge of the parameter field to open the Default Element Selection Tool (the Element Picker or the Element Browser) or use the Down-Arrow key (Auto-Complete) on any parameter field to see a complete list of the memory locations that are valid for that parameter of the instruction.
In / Out - specifies the discrete memory location that will be toggled. This can be any writable bit location.
Reset - optionally enable an additional bit location that, when ON, will turn OFF the In / Out Bit location.
Status Display:
The gray triangle at the right end of the input leg indicates this input is edge-triggered, meaning that each time the instruction's input logic transitions from OFF to ON, the specified bit location will be ON for one complete scan.
