GENERAL
The XFL521B, 522B, 523B, and 524B modules are LONMARK
compliant digital and analog I/O modules which can be
installed at strategic locations within a building. These
modules convert sensor readings and provide output signals
used for operating actuators via LONWORKS standard network
variables (SNVTs). Each Distributed I/O module plugs into a
base terminal block allowing communication with controllers
via the built-in Echelon®LONWORKS bus interface. The ter-
minal block provides spring clamp terminals for easy connec-
tion of field cables from the various sensors and actuators.
The modular system allows Distributed I/O modules to be
removed from the system without disturbing other modules.
The module with terminal block mounts easily onto a DIN rail.
When using CARE, the Distributed I/O modules can be
automatically bound and commissioned to the Excel 500
CPU (XC5010C, XC5210C, XCL5010) and XL50. When the
modules are used by other controllers, provided plug-ins
permit the modules to be commissioned by CARE 4.0 or by
any LNS network management tool.
DESCRIPTION
These Distributed I/O modules use a Neuron® chip and an
FTT-10A free topology transceiver for communication on a
LONWORKS bus and comply with LONMARK Application Layer
Guidelines V3.2.

INTEROPERABILITY
The Distributed I/O modules are compliant to the LONMARK
Application Layer Interface Guidelines, version 3.2. The
modules contain a LONMARK Node Object to allow monitoring
and setting the status of the various Sensor / Actuator Ob-
jects, as well as a LONMARK Sensor Object for each input or
an Actuator Object for each individual output.
Upon receiving an update to the NViRequest network vari-
able, the NVoStatus network variable is updated. The defini-
tion of SNVT_obj_request includes an object ID field to allow
the Node Object to report status conditions for all objects on
a node.
All network variables have the NV names in their self-docu-
mentation strings. This allows a network management node
or tool to display meaningful information on a Distributed I/O
module even if it is installed by an EXCEL 500 controller and
not by the tool itself.
The Distributed I/O modules use the standard 6-byte location
string (see Table 2) in the Neuron® chip’s EEPROM to store
the module address (0...15 as set using the rotary HEX
switch in the case of applications prior to CARE 4.0) and the
module type.

Module Type:
0 = XFL521B Analog Input
1 = XFL522B Analog Output
2 = XFL523B Digital Input
3 = XFL524B Digital Output
Table 2. Location string for storing module address
The node self-documentation string contains the module type
and revision in the optional part after the semicolon.
Example:
#pragma set_node_sd_string &3.2@0,3[6;XDO2_2_00
In this example, the module type is "XDO2" ("2" means that
the 3120E5 chip is used) and the revision is "2.00".
LONMARK Node Object
Setting the Node Object to “DISABLE” via nviRequest
suppresses updating of all output NVs and handling of input
NVs. Setting the Node Object to “ENABLE” via nviRequest
returns the module to normal operation.
The Node Object also contains the optional NV nciNetConfig
which is initialized to “CFG_LOCAL” by default. This allows
the Distributed I/O module to set its location string. If a
network management node commands this nci to
“CFG_EXTERNAL”, then the module will no longer modify its
Location String. This nci is stored in EEPROM and remains
there even in the event of a power failure.
LONMARK Sensor/Actuator Objects
All Actuator Objects (contained in the output modules) have
an output NV showing the actual state of the physical output
and whether it is in the automatic or manual override mode.
Note that the output modules have a manual override panel
which can be plugged on or off.
All Sensor Objects (contained in the input modules) have a
configuration property, MaxSendTime, defining the heartbeat
time, i.e. the interval in which output NVs belonging to the
physical inputs will be sent even if their values do not
change.
All Sensor Objects also have a configuration property,
MinSendTime, defining the minimum time which must elapse
before a changed value of an output NV belonging to a
physical input will be sent. This is to limit the network traffic
when sensor values change rapidly.

RQ_SELF_TEST
Upon receiving an update to nviRequest, nvoStatus is
updated.
RQ_SELF_TEST is used only in the XFL522B analog
output module for outputs configured as a motor. In
this case, a synchronization is performed to set the
actuator in the 0% position.
nvoStatus SNVT_obj_status Reports the status of the node upon request through
nviRequest.
nciNetConfig SNVT_config_src CFG_LOCAL (default)
CFG_EXTERNAL
This configuration variable is set to CFG_LOCAL at
the factory and whenever the rotary HEX switch is
reset. If it is set to CFG_EXTERNAL, a network
manager will assign a network address for the node. In
this case, the module will not modify its location string
as long as the rotary HEX switch is not reset.
nvoFileDirectory SNVT_address
Points to a file directory in the address space of the
Neuron® chip containing descriptors for the files in the
module. It is used to access the configuration pro-
perties stored in configuration parameter files
accessed by network management read/write
messages.
SCPTMinSendTime SNVT_time_sec 1.0 to 10.0 sec
(default = 1.0 sec)
Defines the minimum period of time between output
variable transitions. This configuration property is
applicable only to output NVs of the input modules.
SCPTMaxSendTime SNVT_time_sec 1.0 to 6553.4 sec
(default = 60.0 sec)
Defines the maximum time period of time before out-
put NVs are automatically updated. It must be set to a
higher number than SCPTminSendTime. This con-
figuration property is applicable only to output NVs of
the input modules.
XFL52xB Module Response Times
The response time of Distributed I/O modules is defined as
the period of time between the updating of the physical signal
and the updating of the NV (or vice versa). The response
time varies somewhat due to certain factors and is also
dependent upon the module type (see also Table 4).

Fig. 2. LONMARK Object for each analog input
For each Sensor Object, the XFL521B Analog Input
Module provides an additional output NV, SNVT_temp_p,
which communicates the temperature in °C. This allows
this module to be used as a true temperature sensor in an
open LONMARK integration. If the Sensor Object is con-
figured as 0 to 10V, this NV will be invalid (0x7FFF).

nviValue SNVT_switch Receives the value for the output channel.
nvoFeedback SNVT_switch
Transmits the feedback value of the actuator output. If
the manual override switch is set to 0, or if the manual
override module is not plugged in, the feedback output
reflects the value of nviValue. As soon as the manual
override switch is set at the 20% threshold, the
Actuator Objects adopts this manual value. In this
case, the value of nvoFeedback will be 0xFF (invalid)
and the value field will contain the actuator position.
If the actuator is configured as a motor, the position
commanded with the manual override switch will be
reflected in the open/close commands for a floating
actuator.
If the manual override switch is in the automatic posi-
tion, data is transmitted whenever nviValue is written.
If the manual override switch is in the manual position,
data is transmitted whenever the manual position is
changed.
UCPTSensorConfig none
0 = not used
6 = 0 to 10V (default)
7 = motor (floating)
Specifies the actuator output type for an output

UCPTdriveTimeClose SNVT_time_sec 10.0 to 1000 sec
(default = 90.0 sec)
Specifies a floating actuator’s runtime from 100% to
0%.
UCPTdriveTimeOpen SNVT_time_sec 10.0 to 1000 sec
(default = 90.0 sec)
Specifies a floating actuator’s runtime from 0% to
100%.
SCPTdelayTime SNVT_time_sec 0.0 to 10.0 sec
(default = 5.0 sec)
Specifies the delay time before a floating actuator
changes its direction. This avoids mechanical
problems that could occur when the run direction
changes due to an update to nviValue while the
actuator is still moving.
SCPTminDeltaLevel SNVT_lev_cont.
Specifies the delta level for an update to nviValue to
be exceeded before a new position is calculated for
the floating motor model. This is applicable only if the
actuator is configured as a motor.
UCPTsyncMin SNVT_lev_cont 0 to10%
(default = 2%)
Specifies the lower synchronization threshold. If the
actuator is configured as a motor and the value
commanded through nviValue approaches 0%, the
actuator is synchronized to 0% as soon as nviValue
reaches the percentage specified by UCPTsyncMin.
UCPTsyncMax SNVT_lev_cont 90 to 100%
(default = 98%)
Specifies the upper synchronization threshold. If the
actuator is configured as a motor and the value
commanded through nviValue approaches 100%, the
actuator is synchronized to 100% as soon as nviValue
reaches the percentage specified by UCPTsyncMax.
UCPTsyncCharge SNVT_lev_cont 0 to 127.5%
(default = 100%)
Specifies the additional runtime when an actuator per-
forms a synchronization. This is to ensure that the
actuator reaches the end position even if the actuator
position is not what it should be due to inaccuracy.
For example, with UCPTsyncCharge at 100%, an
actuator with a theoretical current position of 20%
would be forced to run 120% of the runtime specified
by UCPTdriveTimeClose if it starts a synchronization
from this point of operation.

For each Sensor Object, the XFL523B Digital Input Module
provides an additional output NV, SNVT_switch. For an open
LONMARK integration, this offers a more convenient way of
accessing the sensor value compared to using the NV
SNVT_count. If the Sensor Object is configured as
“Totalizer”, this NV is invalid (state = 0xFF, value = 0).

totalizer, this NV transmits the number of transitions
from 0 to 1.
UCPTSensorConfig
0 (not used)
1 = binary (default)
2 = totalizer
Specifies the setting for a sensor channel.
UCPTSendOnDelta SNVT_count 0 to 65535
Specifies the difference in totalizer count required
before a transmission of the value output of the
Sensor Object takes place.
SCPTDirection SNVT_state
Used to define the relation between the logical status
of the input and the state of the LED. One bit cor-
responds to one input channel (bit 4 = input channel
12, bit 15 (MSB) = input channel 1). If a bit is clear,
the LED for the channel will be 0=green and 1=red. If
the bit is set, then 0=red and 1=green.
