Note 1: Total input system transfer time = Sample repetition time + Internal processing time
The total input system transfer time increases in propor tion to the number of channels used.
Note 2: The data processed in the analog I/O module can be linear-conver ted 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 allo-
cated to analog I/O modules. See page 24-12.
Note 3: When an error is detected, a corresponding error code is stored to a data register allocated to analog I/O operating
status. See page 24-6.
