sampling rate is faster than the rate at which the network module

polls the [c]FP-AI-110 for data.

Status Indicators

The [c]FP-AI-110 has two green status LEDs, POWER and

READY. After you insert the [c]FP-AI-110 into a terminal base or

backplane and apply power to the connected network module, the

green POWER LED lights and the [c]FP-AI-110 informs the

network module of its presence. When the network module

recognizes the [c]FP-AI-110, it sends initial configuration

information to the [c]FP-AI-110. After the [c]FP-AI-110 receives

this initial information, the green READY LED lights and the

module is in normal operating mode. A blinking or unlit READY

LED indicates an error condition.

Upgrading the FieldPoint Firmware

You may need to upgrade the FieldPoint firmware when you add

new I/O modules to the FieldPoint system. For information on

determining which firmware you need and how to upgrade your

firmware, go to ni.com/info and enter fpmatrix.

Isolation and Safety Guidelines

Caution Read the following information before

attempting to connect the [c]FP-AI-110 to any circuits

thatmay contain hazardous voltages.1

This section describes the isolation of the [c]FP-AI-110 and

itscompliance with international safety standards. The field

wiringconnections are isolated from the backplane and the

inter-module communication bus. The isolation barriers in the

module provide 250Vrms Measurement Category II continuous

channel-to-backplane and channel-to-ground isolation, verified by

2,300Vrms , 5s dielectric withsta nd test.2 The [c]FP-AI-110

provides double insulation (compliant with IEC61010-1) for

1 A hazardous voltage is a voltage greater than 42.4 Vpeak or 60 VDC. When a

hazardous voltage is present on any channel, all of the channels must be considered

to be carrying hazardous voltages. Ensure that all circuits connected to the module

are inaccessible to human touch.

the [c]FP-AI-110.
