Status Indicators - National Instruments FieldPoint FP-PWM-520 Operating Instructions Manual

Output Channel Operation
Each of the PWM output channels uses a period and a duty cycle
setting to determine when to switch its output to the ON or OFF
state.
The output period is the only configuration attribute for each
channel. You can set the period to any value between 1 ms (1 kHz)
and 65,535 ms (0.01525 Hz), in increments of 1 ms.
The output duty cycle is written as the data value for each channel.
You can set the duty cycle to any percentage value between 0% and
100%, with 12-bit resolution (4,096 discrete duty-cycle settings).

Status Indicators

Figure 4 shows the module label and status indicators. To see
wiring diagrams for the input channels, remove the slide-in card.
Figure 4. Status Indicators and Module Label
After you insert the module into a terminal base (and apply power),
the green POWER indicator lights and the FP-PWM-520 informs
the network module of its presence. When the network module
recognizes the FP-PWM-520, it sends initial configuration
information to the FP-PWM-520. After receiving this initial
information, the green READY indicator lights and the
FP-PWM-520 is in its normal operating mode. In addition to the
green POWER and READY indicators, each channel has a
numbered, green, output state indicator that lights when the
channel is in the ON state.
