Assign Operands
RSLogix 5000 software lets you program according to your workflow. You can enter logic without assigning
operands or defining tags. Later, you can go back and assign or define the operands to complete the logic.
A tag name follows this format:
Item Description
A This instruction is missing an operand. You can enter and save logic without assigning
operands. This lets you develop your logic in iterations and save libraries of code for re-use.
B This is an undefined tag. You can enter and save logic without defining all the tags. This
lets you develop your logic in iterations.
