Accuracy

N/A

1: The 12-bit data (0 to 4095) processed in the analog I/O module can be linear-converted to a value between –32768 and 32767. The optional range

designation, and analog I/O data minimum and maximum values can be selected using data registers allocated to analog I/O modules.

2: When an error is detected, a corresponding error code is stored to a data register allocated to analog I/O operating status.
