Explain a function block.
What will be an ideal response?
A function block takes one or more inputs, makes a decision or calculation and then generates one or more outputs. An output of one function block can also be the input to other function blocks. In the case of the Allen-Bradley Logix5000 controllers, the user must create a function block routine to program and use FBD instructions. A Jump-to-Subroutine (JSR) instruction is typically used to run a function block routine from the main routine or another routine.
