Description: Sets the type of analog inputs.
p0756[0...1] = 0, 1, 4 corresponds to a voltage input (r0752, p0757, p0759 are displayed in V).
p0756[0...2] = 2, 3 corresponds to a current input (r0752, p0757, p0759 are displayed in mA).
p0756[2...3] = 6, 7 corresponds to a resistor input for temperature measurement (r0752, p0757, p0759 are dis-
played in °C).
p0756[2...3] = 8 No temperature sensor connected. Mode for deactivating sensor monitoring (alarm A03520).
In addition, the associated DIP switch must be set.
For the voltage input, DIP switch AI0/1 must be set to "U".
For the current input, DIP switch AI0/1 or AI2 must be set to "I".
For the temperature input, DIP switch AI2 must be set to "TEMP".
Value: 0: Unipolar voltage input (0 V ... +10 V)
1: Unipolar voltage input monitored (+2 V ... +10 V)
2: Unipolar current input (0 mA ... +20 mA)
3: Unipolar current input monitored (+4 mA ... +20 mA)
4: Bipolar voltage input (-10 V ... +10 V)
6: Temperature sensor Ni1000
7: Temperature sensor PT1000
8: No sensor connected
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
[2] = AI2 (T. 50/51)
[3] = AI3 (T. 52/53)
Dependency: Refer to: A03520
Warning: The maximum voltage difference between analog input terminals AI+, AI-, and the ground must not exceed 35 V.
If the system is operated when the load resistor is switched on (DIP switch set to "I"), the voltage between differen-
tial inputs AI+ and AI- must not exceed 10 V or the injected 80 mA current otherwise the input will be damaged.
Note: When changing p0756 , the parameters of the normalization characteristic (p0757, p0758, p0759, p0760) are over-
written with the following default values:
For p0756 = 0, 1, 4, p0757 is set to 0.0 V, p0758 = 0.0 %, p0759 = 10.0 V and p0760 = 100.0 %.
For p0756 = 2, p0757 is set to 0.0 mA, p0758 = 0.0 %, p0759 = 20.0 mA and p0760 = 100.0 %.
For p0756 = 3, p0757 is set to 4.0 mA, p0758 = 0.0 %, p0759 = 20.0 mA and p0760 = 100.0 %.
For p0756 = 6, 7, p0757 is set to 0 °C, p0758 = 0.0 %, p0759 = 100 °C and p0760 = 100.0 %.
Description: Sets the normalization characteristic for the analog inputs.
The normalization characteristic for the analog inputs is defined using two points.
This parameter specifies the x coordinate (V, mA, °C) of the 1st value pair of the characteristic.
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
[2] = AI2 (T. 50/51)
[3] = AI3 (T. 52/53)
Note: The parameters for the characteristic do not have a limiting effect.
