FUNCTION_BLOCK E_LDU

An instance of this function block type models the loading and unloading of a workpiece on a mechanism such as a transfer bar or slide. Loading of workpiece with characteristics given by the S1 and W1 inputs occurs in response to an event at the LD1 input, and unloading occurs upon occurrence of an event at the UNLD input. After unloading, the workpiece style is as given by the S0 input (typically VSTYLE#EMPTY or VSTYLE#NONE). See the VSTYLE data type for the semantics of the S0 and S1 inputs.
