Displays the actual input current in mA when set as current input and with the load resistor switched in.
Index: [0] = AI 0 (X521.1/X521.2, S5.0)
[1] = AI 1 (X521.3/X521.4, S5.1)
Dependency: The type of analog input AI x (voltage or current input) is set using p4056.
Refer to: p4056
Note: AI: Analog Input
Description: Sets the smoothing time constant of the 1st-order low pass filter for the analog inputs of Terminal Module 31 (TM31).
Index: [0] = AI 0 (X521.1/X521.2, S5.0)
[1] = AI 1 (X521.3/X521.4, S5.1)
Note: AI: Analog Input
Description: Displays the currently referred input value of the analog inputs of Terminal Module 31 (TM31).
When interconnected, the signals are referred to the reference quantities p200x and p205x.
Index: [0] = AI 0 (X521.1/X521.2, S5.0)
[1] = AI 1 (X521.3/X521.4, S5.1)
Note: AI: Analog Input
Description: Sets the type of analog inputs of Terminal Module 31 (TM31).
p4056[x] = 0, 4 correspond to a voltage input (r4052, p4057, p4059 are displayed in V).
p4056[x] = 2, 3, 5 correspond to a current input (r4052, p4057, p4059 are displayed in mA).
In addition, the associated switch S5 must be appropriately set.
AI 0: S5.0 = V --> voltage input, S5.0 = I --> current input (burden resistor = 250 Ohm)
AI 1: S5.1 = V --> voltage input, S5.1 = I --> current input (burden resistor = 250 Ohm)
Value: 0: Unipolar voltage input (0 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)
5: Bipolar current input (-20 mA to +20 mA)
Index: [0] = AI 0 (X521.1/X521.2, S5.0)
[1] = AI 1 (X521.3/X521.4, S5.1)
Warning: The maximum voltage difference between the analog input terminals AI+, AI- and the ground of the TM31 (X520.6,
X530.3) may not exceed 35 V.
For operation with the load resistor switched in, the voltage between the differential inputs AI+ and AI- may not
exceed 15 V or the impressed current of 60 mA; if this is not carefully observed, the input will be damaged.
Notice: For operation as a voltage input/current input, switch S5.0 or S5.1 must be appropriately set.
