LABEL - Program Label

The Program Label (LABEL) instruction marks a location in a code block (Program or Task) that can be the target of a Go To Label (GOTO) instruction.

 

All of the Labels must have a unique number.

 

Note: This instruction is a 'power-rail' instruction. Even though the instruction is displayed in the left-most column of the ladder diagram (the power rail), it is created in the right-most column of the ladder logic diagram (the output column). Creating these instructions in Do-more Designer is a bit counter-intuitive because the first step is to position the edit cursor in the output column of the ladder logic diagram (the far right) instead of positioning it against the power rail (the far left).

 

Parameters:

Label - is a number that uniquely defines this label. This can be any constant value between 0 and 65535.
