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, 10 corresponds to a resistor input for temperature measurement (r0752, p0757, p0759 are
displayed in °C).
p0756[2...3] = 8 No temperature sensor connected. Mode for deactivating sensor monitoring (alarm A03520).
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 to +20 mA)
4:
Bipolar voltage input (-10 V ... +10 V)

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, the voltage between differential 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 scaling characteristic (p0757, p0758, p0759, p0760) are overwritten with
the following default values:
For p0756 = 0, 4, p0757 is set to 0.0 V, p0758 = 0.0 %, p0759 = 10.0 V and p0760 = 100.0 %.
For p0756 = 1, p0757 is set to 2.0 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 scaling characteristic for the analog inputs.
The scaling characteristic for the analog inputs is defined using 2 points.
This parameter specifies the x coordinate (V, mA, °C) of the 1st value pair of the characteristic.
