Excel Smart I/O Compact
GENERAL
The Excel Smart I/O Compact is suitable for installation at
strategic locations throughout your buildings (see Table 1 for
an overview of versions).
It features three digital inputs, three analog inputs, three relay
outputs, as well as an input/output functionality which
supports a switching logic functionality (see Fig. 1).

Fig. 1. Switching logic functionality
Example application 1: Monitoring of up to three springreturn damper actuators (no floating actuators)
A relay output can be used to open/close a damper, while the
inputs can be used to check if the end position has been
reached. This offers considerable time savings compared to
manual service. (This example application does not require
switching logic functionality.)
Application example 2: Switching a light via an
occupancy sensor or LONWORKS
An occupancy sensor can be used to switch ON/OFF a light
(with configurable hold-time) in e.g. a lavatory. This
application uses the switching logic functionality and runs
independently of the main CPU (e.g. XL500).

General
The Excel Smart I/O Compact is available in two versions with
different power supply voltage:
• XFCL2A1: 230 Vac [-15% / +10%], 50/60 Hz
• XFCL3A1: 24 Vac [±20%], 50/60 Hz
Both versions have three digital inputs, three analog inputs,
and three normally-open contact relays. Both versions are
equipped with a L
service LED.
The analog inputs of both versions have an individually
configurable offset. They have a 10-bit resolution, with a
typical accuracy of ±0.1 V and an impedance of > 100 kOhm
to GND for voltage input.
Both versions can be equipped with optional terminal
protection covers and swivel label holders (see section
"Accessories"). The Excel Smart I/O Compact has a
configurable receive / sent heart beat time (0…6553 s).
Analog Input Configuration Options
• NTC20k sensor input with optional sensor offset. The
threshold for the L
noise filter is selected by default.
• Slow DI with direct / reverse configuration option.

Fig. 4. Relay outputs
• Normally-open contacts with a common terminal for all
three relays (max. 3 A in total).
• Configurable start-up / communication failure state (e.g.
logical ON or OFF) in event of a communication failure.
• Configurable delay time and delay type (delayed ON,
delayed OFF, or delayed ON and OFF.
• Configurable switching level and hysteresis.
Example: Relay output is controlled by nviDoSwitch[1]
(SNVT_switch, 0…100%). Switching level is 20% and
hysteresis is 5%. The relay is switched ON at 20% and
OFF at 15%.

EXCEL SMART I/O COMPACT MODULES
• The switching logic functionality is configured using CARE
7.01.00 (or later).
• Excel Smart I/O Compact supports up to three switching
logic tables. Each logic table may have up to six condition
inputs and up to four condition cases.
• A condition input may be any of the inputs / outputs or the
respective input NV's.
• The output is switched if one of the condition columns is
TRUE. The relay output which will then be switched can
be selected. The switching logic has a higher priority than
a binding to the output.
• The following condition types may be selected: rising edge
for pulse input, falling edge for pulse input, >, >=, <, <=,
==, or !=.
• The comparison value may be a fixed value e.g. totalizer
value, an NV state e.g. invalid, an input NV, an input, or
an output.
Behavior in the Event of Sensor Break
In the event of a break in an NTC20k sensor, the conditions
"<", "<=", ">", and ">=" will be ignored.
If necessary, the break of an NTC20k sensor can be checked
using the condition "=invalid".
Excel Smart I/O Compact Response Times
Response Time for NV Update
The response time is defined as the interval between the
updating of the physical signal and the updating of the corresponding NV (or vice versa). Response times vary somewhat due to various factors. Assuming that only a single
digital input changes at any given time, the corresponding
response times is approx. 1.5 s. Thus, depending upon your
specific circumstances, the Excel Smart I/O Compact may be
suitable for rapid-response applications.
Response Time for Switching Logic
If you require a fast response time, you must use digital inputs
in a switching logic table. Analog inputs used as slow digital
input require a longer response time.
Typical response time for reaction to DI change:
• If only a single switching table is defined, the reaction time
to a digital input change is less than 0.5 s.
Typical response time for reaction to slow DI change:
• If only a single switching table is defined, the reaction time
to a slow digital input change is less than 1.5 s.
INTEROPERABILITY
The Excel Smart I/O Compact is compliant with LONMARK
Application Layer Guidelines V3.3.
LONWORKS Network Interface
The Excel Smart I/O Compact is equipped with a 10-MHz
3150 Neuron® chip. It communicates within the LonWorks
network at a rate of up to 78 kilo baud via an FT-X1 Free
Topology Twisted Pair Transceiver (compatible with FTT10A
transceivers).
Devices can be wired in daisy chain, star, or any combination
thereof as long as the max. wire length requirements are met.
The recommended configuration is a daisy chain with two
termination modules. This layout allows for max. bus length,
and its simple structure presents the least number of possible
problems, particularly when adding on to an existing bus. For
more information, refer to http://www.echelon.com
.
LONWORKS Service Button
All models feature a LONWORKS service button accessible
from the outside (see Fig. 2).
The service pin message is broadcast on the network
whenever the service button is pressed, but also after every
reset (due to power-up or software reset) and whenever the
mode is changed from offline to online.
LONWORKS Service LED
All models feature a LONWORKS service LED (see Fig. 2). For
more information on standard service LED behavior, refer to
the Excel Smart I/O Compact Installation Instructions
(EN1B0282-GE51).
Configuration and Binding
The switching logic functionality is configured using
Honeywell’s CARE 7.01.00 (or later) tool. The I/O functionality
can be configured using either CARE 7.01.00 (or later) or the
LNS plug-in. The LNS plug-in cannot be used to configure the
switching logic functionality.
NOTE: Do not use a browser for configuration as there is
then a high risk of incorrect configuration.
LONMARK Objects
The Excel Smart I/O Compact features:
• One Node Object (Obj#0);
• Three Open-Loop Sensor objects (Obj#1-3), one for each
physical universal input;
• Three Open-Loop Sensor objects (Obj#4-6), one for each
physical digital input;
• Three L
for each relay.
LONMARK Node Object
The LONMARK node object (see Fig. 6) allows the various
different objects in a node to be monitored. Upon receiving an
update to nviRequest, nvoStatus is updated. The definition of
SNVT_obj_request includes an object ID field to allow the
node object to report status conditions for all objects in a
node. The node self-documentation string lists the names of
the individual L
management node or tool to display useful information about
an Excel Smart I/O Compact; it also states (in the optional
part after the semicolon) that the node is an Excel Smart I/O
Compact, and lists its version number. The Excel Smart I/O
Compact has a configurable receive / sent heart beat time
(0…6553 s).
