Overview
Commissioning
Analogue Input AE/S 4.2 is loaded with the "Threshold value measure-
ment /1" application program. The programming requires ETS2 V 1.3 or
higher. When using ETS3, a file of type ".VD3" must be imported.
A maximum of 42 communication objects, 100 group addresses and
100 assignments can be linked.
The following functions can be selected for each of the four inputs:
Sensor output
All conventional sensors with a sensor output signal of 0–1 V, 0–5 V,
(type of input
0–10 V, 1–10 V, 0–20 mA, 4–20 mA, 0–1000 ohm resistance, PT100 in
signal)
2-conductor technology – 30...+ 70 °C, PT100 in 2-conductor technology
– 200...+ 800 °C or floating contact interrogation can be connected.
Signal correction/
The sensor signal can be corrected or adjusted.
adjustment
Measuring range
Flexible setting option for the upper and lower measuring limit dependent
on the sensor's output signal. The measurement curve is adapted linearly
between the upper and lower measuring limit.
Output value
Flexible setting options for the output value. For the upper and lower
measuring limit dependent on the sensor's output signal.
Data types of the
The output value can be sent as a 1-bit value [0/1], 1-byte value
output 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] or
4-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 and
averaging are available.
