An instance of this function block type provides the logic for sortation of a metallic peg from a non-metallic ring, with "anti-jamming" interlocking to prevent the deflection of a ring into a chute where a ring is already present. Its operation is defined by the Execution Control Chart (ECC) and Ladder Diagram (LD) REQ algorithm shown above.

The input and output variables of this function block type correspond to the similarly named outputs and inputs, respectively, of the Sortation/Inspection testbed.

See the TESTBED_MVCL system configuration for an example of the use of an instance of this type.
