= Update Period

For the fastest performance, configure all unused channels for the 
500 Hz filter setting and for an input range in use on one or more 
other channels with the 500 Hz filter setting. For example, if 
10 channels are configured for 0–10 V input and 500 Hz, four 
channels are configured for 0–5 V and 60 Hz, and two channels 
are unconnected, use the FieldPoint software to configure the 
unconnected channels for 0–10 V input and 500 Hz filter setting.

Some combinations of two input ranges count as only one range for 
calculating update rates. Those combinations are 

±60 mV and 

±300 mV; 0–1 V and 0–5 V; and ±1 V and ±5 V.

The update rate does not affect the rate at which the network 
module reads the data. Set up your application so that the update 
rate is faster than the rate at which the network module polls the 
[c]FP-AI-112 for data.

The [c]FP-AI-112 has two green status LEDs, POWER and 
READY. After you insert the [c]FP-AI-112 into a terminal base or 
backplane and apply power to the connected network module, the 
green POWER indicator lights and the [c]FP-AI-112 informs the 
network module of its presence. When the network module 
recognizes the [c]FP-AI-112, it sends initial configuration 
information to the [c]FP-AI-112. After the [c]FP-AI-112 receives 
this initial information, the green READY indicator lights and the 
module is in normal operating mode.

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
