FP-PG-522 and cFP-PG-522 10 ni.com
When the network module recognizes the [c]FP-PG-522, it sends
initial configuration information to the [c]FP-PG-522. After the
[c]FP-PG-522 receives this initial information, the green READY
indicator lights and the [c]FP-PG-522 is in normal operating mode.
In addition to the green POWER and READY indicators, each
channel has a numbered, green activity indicator that lights when
the channel is actively generating pulses. The LED does not
indicate whether the channel is currently in the ON or the OFF
state.
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

Isolation and Safety Guidelines
Caution Read the following information before
attempting to connect the [c]FP-PG-522 to any circuits
that may contain hazardous voltages.
This section describes the isolation of the [c]FP-PG-522 and its
compliance with international safety standards. The field wiring
connections are isolated from the backplane and the inter-module
communication bus. The isolation is provided by the module,
which has optical and galvanic isolation barriers designed and
tested to protect against transient fault voltages of up to 2,300 Vrms.
Follow these guidelines to ensure a safe total system:
• The [c]FP-PG-522 has a safety isolation barrier between the
I/Ochannels and the inter-module communication bus. There
is no isolation between channels unless otherwise noted. If any
of the channels on a module are wired at a hazardous potential,
make sure that all other devices or circuits connected to that
module are properly insulated from human contact.
•Do not share the external supply voltages (the V and
Cterminals) with other devices (including other FieldPoint
devices), unless those devices are isolated from human contact.
• For Compact FieldPoint, you must connect the protective earth
(PE) ground terminal on the cFP-BP-x backplane to the system
safety ground. The backplane PE ground terminal has the
