9ABB i-bus ® EIB / KNX Commissioning3 Commissioning3.1 Overview Analogue Input AE/S 4.2 is loaded with the “Threshold value measure-ment /1” application program. The programming requires ETS2 V 1.3 orhigher. When using ETS3, a file of type “.VD3” must be imported.A maximum of 42 communication objects, 100 group addresses and100 assignments can be linked.The following functions can be selected for each of the four inputs:Sensor output(type of inputsignal)All conventional sensors with a sensor output signal of 0–1 V, 0–5 V,0–10 V, 1–10 V, 0–20 mA, 4–20 mA, 0–1000 ohm resistance, PT100 in2-conductor technology – 30...+ 70 °C, PT100 in 2-conductor technology– 200...+ 800 °C or floating contact interrogation can be connected.Signal correction/adjustmentThe sensor signal can be corrected or adjusted.Measuring range Flexible setting option for the upper and lower measuring limit dependenton the sensor’s output signal. The measurement curve is adapted linearlybetween the upper and lower measuring limit.Output value Flexible setting options for the output value. For the upper and lowermeasuring limit dependent on the sensor’s output signal.Data types of theoutput valueThe output value can be sent as a 1-bit value [0/1], 1-byte value[0...+ 255], 1-byte value [– 128...+ 127], 2-byte value [0...+ 65.535],2-byte value [– 32.768...+ 32.767], 2-byte value [EIB floating point] or4-byte value [IEE floating point].Filtering Measured values can be averaged over 4, 16 or 64 measurements.One measurement is taken every second.Threshold value 2 threshold values can be set, each with an upper and lower limit.The limits can be modified via the bus.Calculation This enables 2 values to be compared or calculated mathematically.The options smaller than, greater than, addition, subtraction andaveraging are available.Fig. 8: Functions of the application program
