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 |
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 ±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 | |||||
Offset/gain adjustment | Supported | --- | ||||
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 sup |
