Input functions
Mean value processing: Stores the last “n” data conversions in the buffer, and stores the mean value of the conversion values. Buffer number: n = 2, 4, 8, 16, 32,
64, 128, 256, 512
Peak value holding: Stores the maximum conversion value while the Peak Value Hold Bit is ON.
Scaling : Setting values in any specified unit within a range of 卤32,000 as the upper and lower limits allows A/D conversion to be executed and analog signals to
be output with these values as full scale.
Input disconnection detection: Detects the disconnection and turns ON the Disconnection Detection Flag. *10
Direct conversion : A/D conversion is performed and the converted value is refreshed when the ANALOG INPUT
DIRECT CONVERSION instruction (AIDC) is executed.
This instruction is supported by the CJ2H-CPU[][](-EIP) CPU Units with unit version 1.1 or later, and CJ2M-CPU[][].
CJ1, NJ501, and CP1H CPU Units and NSJ Controllers do not support direct conversion
