GENERAL

Excel Smart I/O modules are LONMARK association-compliant
devices, and can thus be used in all open L
ments. They feature a variety of software-configurable digital
and analog inputs and outputs and are suitable for installation
at strategic locations throughout your buildings. The modules
convert physical input signals from sensors into network
variables and the network variables into physical output
signals for operating actuators.

The diverse mix of inputs and outputs (flexibly configurable
using Honeywell's LonMaker for Windows™ plug-in) makes
the Excel Smart I/O ideally suited for a wide range of
intelligent, distributed applications.

Table 1 provides a brief overview of the available versions.

Description

EXCEL SMART I/O MODULES

DESCRIPTION

With the Excel Smart I/O, you can choose from among ten
variants featuring different assortments of universal inputs,
digital inputs, analog outputs, and relays for use in conjunc­tion with a wide range of sensor types and actuators. All
module inputs and outputs are protected against overvoltages
of max. 40 Vdc and 24 Vac. An extra power output terminal
accompanying each analog input/output can also be used to
power 24 Vac field devices.

Further, the individual inputs and outputs can be flexibly con­figured using Honeywell's LonMaker for Windows software
plug-in. Thus, each of the four fast digital inputs can be con­figured for static input from dry contacts or open collectors or
for totalizing signals having a frequency of up to 20 Hz, while
the universal inputs can be configured for analog signals from
specific sensor types (model-dependent), or for voltage­variable input, or for slow digital input (max. frequency =

0.25 Hz).
The XFC1D06, XFC2D05 and XFC2D06 as well as the

XFC3D04, XFC3D05, and XFC3D06 are equipped with six 3­position manual override switches. Using Honeywell's soft­ware plug-in, these switches can be configured to override the
individual relays or analog outputs. These modules also
feature ten status LEDs showing the condition of the inputs /
outputs allocated to them.

The XFC2A05, XFC2A06, XFC2D05, and XFC2D06 (long
housing) are equipped with a transformer enabling them to be
powered with 230 Vac (+10%/-15%). The XFC1A06 and
XFC1D06 (long housing) have a transformer enabling them to
be powered with 110 Vac (+10%/-15%). For both the 230 Vac
and 110 Vac models, the standby power consumption (= all
outputs are inactive, all inputs are open, and all LEDs –
except the power LED – are OFF) is less than 10 VA. All
other models (short housings) require 24 Vac (±20%); their
standby power consumption is less than 5 VA.

All modules are equipped with a power LED as well as with a
L

ONWORKS service button and corresponding service LED.

Matching terminal protection covers and swivel label holders
are available for all modules.

• four LONMARK open-loop sensor objects (Obj#1-4) (one for
each universal input),

• four L

ONMARK open-loop sensor objects (Obj#5-8) (one for

each digital input),

• two L

ONMARK open-loop actuator objects (Obj#9-10) (one

for each analog output), and

• four L

ONMARK open-loop actuator objects (Obj#11-14) (one

for each relay).

LONMARK Node Object

The LONMARK node object 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
ment node or tool to display useful information about an Excel
Smart I/O; it also states (in the optional part after the
semicolon) that the node is an Excel Smart I/O, and lists its
version number.

Example:

network input sd_string("@x|y") SNVT_xxx
nvName;

where input can be replaced by output, x refers to the
object x listed within set_node_sd_string, and y is the NV
index within the following L

INTEROPERABILITY

The Excel Smart I/O is compliant with LONMARK Application
Layer Guidelines V3.2. and thus interoperable with all other
devices in open L
devices). See also section "LonWorks Network Interface."

Excel Smart I/O Module Response Times

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 will typically amount to approx. 1 sec. Thus,
depending upon your specific circumstances, the Excel Smart
I/O may be suitable for rapid-response applications.

LONMARK Objects

The Excel Smart I/O features a total of 15 LONMARK objects:

• one LONMARK node object (Obj#0) to allow monitoring and
setting the status of the various sensor / actuator objects,

RQ_NORMAL returns the object to the enabled, non-overridden state.
RQ_DISABLED disables the object.
RQ_ENABLE enables the object.
RQ_UPDATE_STATUS posts the current settings of the flags of the specified object.
RQ_REPORT_MASK reports the supported flags of the specified object.
RQ_RESET resets the appropriate LONMARK object: If the digital input object is configured
for totalizing, it resets the totalizer to 65535 (0xFFFF); if associated to the node object, it
resets the node.
RQ_CLEAR_RESET requests that reset_complete be cleared.
All other requests read to an "invalid_request" error.
object_id is the ID of the object within the node.
For invalid_id, a value of "1" means that the requested object ID is not implemented in this
node.
For invalid_request, a value of "1" means that unimplemented function has been
requested.
For disabled, a value of "1" means that the object has been disabled: those I/O objects not
supported by the current hardware type will always be disabled.
For open_circuit, a value of "1" means that an open circuit has been detected.
For unable_to_measure, a value of "1" means that an I/O line has failed.
For comm_failure, a value of "1" means that network communications have failed: one or
more bound input NVs specified for receive heartbeat weren't updated within the
configured receive heartbeat time.
For manual_control, a value of "1" means that the actuator is under local control: this field
applies to the output objects and the node object, only, and notifies whether the
appropriate output was manually overridden.
Not supported.
For in_override, a value of "1" means that the module has been overridden via
nviAoManOvrd or nviDoManOvrd (e.g. using the XILON Handheld MMI)
For report_mask, a value of "1" means that the status is an event mask.
Not supported.
For reset_complete, a value of "1" indicates the execution of the reset sequence. After a
reset sequence, the reset flag goes to TRUE (1) and remains in this state until it is cleared

TECHNICAL DATA

General

The Excel Smart I/O is equipped with a 10-MHz 3150
Neuron® Chip (which executes the application program and
implements the LonTalk protocol) and a NEC coprocessor
(for handling the inputs and outputs). It communicates within
the L

ONWORKS network at a rate of 78 kilobaud via an FTT-

10A Free Topology Twisted Pair Transceiver
Each module is equipped with four 230 Vac, 6 A digital

outputs, i.e. relays (including two normally open [N.O.] and
two changeover [C.O.] relays). Floating actuators can be
directly connected to these relays once they have been
configured using Honeywell's LonMaker for Windows plug-in.

Further, each Excel Smart I/O is equipped with four fast digital
inputs. Each fast digital input can be reconfigured (using the
Honeywell plug-in) to accept static input (from dry contacts or
open collectors) or to totalize input signals (having a
frequency of up to 20 Hz).

Depending upon the given model, each module is also
equipped with a varying number of different universal inputs
and analog outputs (see section "Universal Inputs and Analog
Outputs" below), each of which has an extra power output
terminal for supplying 24 Vac power to field devices.

Certain models also feature six 3-position manual override
switches and ten status LEDs (see section "Manual Overrides
and Status LEDs" below).

Optional accessories include swivel label holders and terminal
protection covers (see "Optional Accessories" below).

A power LED, a L
ponding L

ONWORKS service button (see sections "LONWORKS

Service LED" and "L

ONWORKS service LED, and a corres-

ONWORKS Service Button" below) are

located on the top of each module.
There are two standard module sizes: the long module (with a

built-in 230 Vac transformer) and the short module (which
requires 24 Vac power). See section "Long and Short
Housings" below.

Universal Inputs and Analog Outputs

Further, depending upon the given model, the modules are
equipped with a variable number of different universal inputs
and analog outputs.

Universal Inputs

The term "universal inputs" refers to analog inputs for
temperature-sensor signals which can also be reconfigured
(using the Honeywell plug-in) as voltage-variable or slow
digital inputs (e.g. for dry-contact/open-collector signals).

Each module is equipped with universal inputs of one of the
following three types:

EN0B-0311GE51 R0708 6

EXCEL SMART I/O MODULES

• The first type can be configured for analog signals from
NTC20k sensors or for 0...10 Vdc/2..10 Vdc voltage
signals or for slow digital input (max. frequency = 0.25 Hz).

• The second type can be configured for analog signals from
three-wire PT100 sensors or for 0...10 Vdc/2..10 Vdc
voltage signals or for slow digital input (max. frequency =

0.25 Hz). The XFC3A04001 and XFC3D04001 are
equipped with two universal inputs of this type, the
reconfiguration of which yields four voltage-variable or slow
digital inputs.

• The third type can be configured for analog signals from
PT1000, Ni1000, and Ni1000TK5000 sensors or for

0...10 Vdc/2..10 Vdc voltage signals or for slow digital input
(max. frequency = 0.25 Hz).

The universal inputs of all models have an individually
configurable offset.

The universal inputs of the XFC3A06001, XFC3D06001,
XFC2A06001, and XFC2D06001 have a 10-bit resolution,
with a typical accuracy of ±0.1 V and an impedance of
> 100 kOhm to GND for voltage input.

The universal inputs of the XFC3A04001 and the
XFC3A05001 have a 12-bit resolution, with a typical accuracy
of ±0.075 V and an impedance of > 100 kOhm to GND for
voltage input.

Each universal input features an extra power output terminal
for supplying 24 Vac power to active sensors.

Analog Outputs

Each module is equipped with two analog outputs providing
either 0...11 VDC, 0…±1.1 mA signals or 0..20 mA/4..20 mA
signals (model-dependent). Each analog output features an
extra power output terminal for supplying 24 Vac power to
actuators.

The analog outputs have a permissible load of > 10 kOhm,
and a typical accuracy of ±0.2 V.

Other Module-Specific Features / Options

Manual Overrides and Status LEDs

The XFC1D06, the XFC2D05 and XFC2D06, as well as the
XFC3D04, 3D05, and 3D06 are each equipped with six 3­position (ON, OFF, AUTO) manual override sliding switches
with which the individual digital/analog output signals can be
overridden. The manual override switches can be configured
using Honeywell's plug-in.

These same modules are each equipped with a total of ten
colored status LEDs:

• The four 3-color software-configurable LEDs can be used
to test whether signals from e.g. digital inputs are
changing. They can also indicate whether the hardware is
defective.

• The four yellow software-configurable LEDs are ordinarily
used for relays.

• The two red variable-intensity LEDs are connected to the
analog outputs; their brightness varies according to the
strength of the corresponding signal (i.e. 0 volts / 0 mA =
dark LED, 10 volts / 20 mA = bright LED)

See also the section of the plug-in's on-line help on status
LED configuration.

Long and Short Housings

The XFC2A05 and XFC2A06 as well as the XFC2D05 and
XFC2D06 are each equipped with a transformer enabling
them to be powered with 230 Vac, and they thus feature long
housings (W x L x H = 180 x 76 x 110 mm). The XFC1A06
and XFC1D06 have a transformer enabling them to be
powered with 110 Vac, and likewise feature long housings. All
other models require a 24 Vac power supply and are
enclosed in short housings (W x L x H = 126 x 76 x 110 mm).

Optional Accessories

Optional accessories include matching terminal protection
covers (available in packs of 8) and swivel label holders
(available in packs of 8).

Those Excel Smart I/O modules featuring override switches
require swivel label holders onto which the labels containing
customer-specific wiring information can be applied. The
swivel label holders are snapped into place on the housing.

LONWORKS Network Interface

The Excel Smart I/O communicates within the LONWORKS
network at a rate of 78 kilobaud via an FTT-10A Free
Topology Twisted Pair Transceiver. This transceiver provides
transformer isolation so that the bus wiring does not have a
polarity.

Devices equipped with this transceiver can be wired in daisy
chain, star, loop, 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 maximum bus length, and its simple
structure presents the least number of possible problems,
particularly when adding on to an existing bus. For more
information, please refer to http://www.echelon.com

Configuration and Binding

The network variables of the Excel Smart I/O are configured
and bound using Honeywell's LonMaker for Windows™ plug­in.

Wiring Check

The XILON Handheld MMI is used to check the wiring of the
modules.

User Guide (EN2B-0214GE51) for more information.

ONWORKS Networks

LONWORKS Service Button

All models feature a LONWORKS service button accessible
from the outside on the top of module for use in installation
and troubleshooting. When the service button is pressed, the
following actions take place:

• The service pin message is issued on the network.

• When the service button has been pressed longer than 30

sec, the node reverts to normal mode.

The service pin message is broadcast:

• whenever the service button has been pressed;

• after each reset due to power-up, software reset;

• when changing the mode from offline to online.

See also Excel Smart I/O Installation Instructions (EN1B­0180GE51) for more-detailed information.

LONWORKS Service LED

All models feature a LONWORKS service LED connected to the
Neuron® Chip service LED output. The service LED displays
numerous different behaviors indicating various module states
for use in troubleshooting.

See also Excel Smart I/O Installation Instructions (EN1B­0180GE51) for a complete description of these behaviors.
