OUTPUT_REF_MULTIEDGE

The data type OUTPUT_REF_MULTIEDGE contains data describing the state of a digital output. In addition to the switching state it contains time stamps for state changes. The data type is used in conjunction with terminals that allow multiple switching operations per PLC cycle by means of multi-timestamp.
