Selecting one of these inputs by setting the corresponding bit to 1 enables the logic function for the output identified by the index within this table. The calculation take place in 4 steps: 1. Selecting inputs (wtWebioEA12x6RelPortLogicInputMask) 2. Inverting inputs if necessary (wtWebioEA12x6RelPortLogicInputInverter) 3. Logical combination (wtWebioEA12x6RelPortLogicFunction) 4. Inverting the result if necessary (wtWebioEA12x6RelPortLogicOutputInverter) OCTET 1: unused OCTET 2: unused OCTET 3: Bit 0-3 : inputs 8-11 Bit 4-7 : unused OCTET 4: Bit 0-7 : inputs 0-7
