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 (wtWebioEA24oemPortLogicInputMask) 2. Inverting inputs if necessary (wtWebioEA24oemPortLogicInputInverter) 3. Logical combination (wtWebioEA24oemPortLogicFunction) 4. Inverting the result if necessary (wtWebioEA24oemPortLogicOutputInverter) OCTET 1: unused OCTET 2: Bit 0-7 : inputs 16 - 23 OCTET 3: Bit 0-7 : inputs 8 - 15 OCTET 4: Bit 0-7 : inputs 0 - 7
