Notes:
1. Total input system transfer time = Sample repetition time + Internal processing time. The
total input system transfer time increases in proportion to the number of of channels used.
2. The data processed in the analog I/O module can be linear-converted to a a value between
–32768 and 32767. The 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.
3. When an error is detected, a corresponding error code is stored to a data register allocated
to analog I/O operating status.
4. The value is measured when a 500V clamp voltage is applied to the power supply and I/O
lines.
