GENERAL
Excel Smart I/O modules are LONMARK association-compliant devices, and can thus be used in all open LONWORKS environments. 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. See Table 4 on page 10 for details.

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 3- position 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 LONWORKS service button and corresponding service LED.
Matching terminal protection covers and swivel label holders are available for all modules.
INTEROPERABILITY
The Excel Smart I/O is compliant with LONMARK Application Layer Guidelines V3.2. and thus interoperable with all other devices in open LONWORKS networks (including third-party 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,
•four LONMARK open-loop sensor objects (Obj#1-4) (one for each universal input),
•four LONMARK open-loop sensor objects (Obj#5-8) (one for each digital input),
•two LONMARK open-loop actuator objects (Obj#9-10) (one for each analog output), and
•four LONMARK 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 LONMARK objects, allowing a network management 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 LONMARK object definition:
set_node_sd_string "&"&3.2@0,1[4AI,1[4DI,3[2AO,3[4DO;SmartIO_01"

Description |
|
|
|
RQ_NORMAL returns the object to the enabled, non-overridden state. |
|
|
requestobjSNVT |
RQ_DISABLED disables the object. |
|
nviRequest |
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. |
|
|
statusobjSNVT |
For unable_to_measure, a value of "1" means that an I/O line has failed. |
|
nvoStatus |
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 |
|
|
|
(acknowledged). |

Valid range: 10...6553 s; in increments of 1 s (default = 60.0 s). Defines the maximum |

mechanism. |
|
|
|
Valid range: Pre-set at factory. Configures the start-up behavior for input NVs with respect |
|
|
|
to getting an immediate update through a poll request. If enabled, any input NV bound to |
|
UCPT_Poll |
|
another node will initiate a poll request after reset, thus helping to avoid start-up problems |
|
|
|
until the next NV update. Polling based on a time grid of 1 sec, only. If disabled, the input |
|
|
|
NVs remain invalid until the next update is sent. |

Valid range: Pre-set by application program. Identifies the current application and its |
|
|
