Digital I/O
M Series devices contain up to 32 lines of bidirectional DIO signals on
Port 0. In addition, M Series devices have up to 16 PFI signals that can
function as static DIO signals.
M Series devices support the following DIO features on Port 0:
•
Up to 32 lines of DIO
•
Direction and function of each terminal individually controllable
•
Static digital input and output
•
High-speed digital waveform generation
•
High-speed digital waveform acquisition
•
DI change detection trigger/interrupt
Figure 6-1 shows the circuitry of one DIO line. Each DIO line is similar.
The following sections provide information about the various parts of the
DIO circuit.
