CFG_CURRENT_4TO20MA_EXCEPTIONSETTING gets/sets the mechanism for returning the data when the input is below 4mA in 4-20mA current measurement.
| Type | INT32U[] |
| Length | MAX_AI_CHANNELS * 4bytes (8 * 4bytes) |
| Access type | Read/Write |
| Value | Each element in the array represent the settings for the corresponding channel. For USB-4718, the channel is
from 0 to 7. Each element should be one of the following values: 0: return the upper limit (20mA) 1: return the lower limit (4mA) 2: return the last correct value |
The operation of this property will change the property value of all the channels, and therefore if you want to change the property value of a specific channel, please get the current property first, and then change the corresponding property element in the array to the value you desired, and set the property by the changed array.
