DEC - Decrement


The Decrement (DEC) instruction decrements the value in the specified Element location by 1. Take note that this instruction is power-flow-based - not edge triggered - which means that it will decrement the specified location each PLC scan in which the input logic is TRUE.

 

 


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.

 

Element - specifies the numeric memory location to decrement. This can be any writable numeric location.
