FP-CTR-500 and cFP-CTR-500

When you set the output to one of the pulse modes, the frequency
of the pulse train (

f

pulse

) is the same as that shown in

Step 2. Set Up

the Pulse Counter

, but the output frequency is half that value when

you set the output channel to one of the toggle modes.

Status Indicators

Figure 12 shows the status indicator LEDs on the [c]FP-CTR-500.

Figure 12.

Status Indicators

The [c]FP-CTR-500 has two green status LEDs,

POWER

and

READY

. After you install the [c]FP-CTR-500 onto a terminal base

or backplane and apply power to the connected network module,
the green

POWER

indicator lights and the [c]FP-CTR-500

informs the network module of its presence. When the network
module recognizes the [c]FP-CTR-500, it sends initial
configuration information to the [c]FP-CTR-500. After the
[c]FP-CTR-500 receives this initial information, the green

READY

indicator lights and the module is in normal operating

mode.

In addition to the green

POWER

and

READY

indicators, each

channel has a numbered, green status indicator that lights when the
channel is in the ON state.

Upgrading Your FieldPoint Firmware

You may need to upgrade your FieldPoint firmware when you add
new I/O modules to your FieldPoint system. For more information
