When a disconnection occurs in an analog input line (voltage input or current
input), the Disconnected Line Detection Flag turns ON for each input that is
valid in the number of AD conversion points. The Disconnected Line Detection
Flags are included in the Analog Status Flags.
When Disconnected Line Detection is enabled, the value of AD conversion
data is set to 7FFF hex. When the input returns to a value within the range
that can be converted, the Disconnected Line Detection function will automat-
ically be turned OFF, and normal data conversion will occur.
Disconnected Line detection is supported for input ranges of 1 to 5 V or 4 to
20 mA only. With the 1 to 5 V input range, a disconnected line is detected
when the input voltage is below 0.76 V (less than 6%). With the 4 to 20 mA
input range, a disconnected line is detected when the input current is below
3.04 mA.
Depending on factors such as the characteristics and connection methods of
the input device, the input can be adjusted to compensate for error in the input
voltage or current. The following diagram shows when compensation is
applied to the conversion line at the two points for 0% and 100%.
The following table shows the input ranges that support user adjustment.
