Terminal Arrangement
The signal names corresponding to the connecting terminals are as shown in
the following diagram.
Note
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.
