1. The analog I/O numbers that can be used are set in the Data Memory
(DM).
2. The I/O signal ranges for individual inputs and outputs are set in the Data
Memory (DM). They can be set in units of I/O numbers.
3. The AG terminal (A7, B7) is connected to the 0-V analog circuit in the Unit.
Connecting shielded input lines can improve noise resistance.
4. The N.C. terminals (A4, B4) are not connected to internal circuitry.
The following diagrams show the internal circuitry of the analog I/O section.
