1 Introduction
1.1 Overview
The L-STAT is a room control device with a modern look that fits any interior design. It is
directly connected to a LOYTEC controller with a Modbus interface such as LIOB-AIR, LROC or L-INX.
Up to 16 L-STAT devices can be connected to one controller to offer control at different
locations for the largest rooms. The L-STAT is equipped with a segmented LCD display
featuring an RGB backlight with adjustable color, offering a neat way to make the L-STAT
match the interior color concept of an office building. Eight capacitive touch buttons are
used to cycle through sensor values, display parameters, and adjust setpoints. Up to four
external buttons can be accessed and processed by the controller.
The L-STAT’s internal sensors measure temperature, humidity, dew point, occupancy and
CO2 level. Sensor values can be displayed in SI or US units. Additionally, the date and time
as well as the current level of eco-friendliness are also displayed on the LCD display.
Parameters controlled by the controller’s logic can be overridden on the L-STAT, such as
for occupancy, air conditioning, and ventilation. A direct access mode is available to
quickly adjust the most important setpoints e.g. for temperature and ventilation control.
A buzzer provides acoustic feedback for the touch buttons and can also be used to indicate
alarms and error states. To prevent unauthorized modifications, two access levels (end user,
system integrator) are used, which are secured via 4-digit pin codes. Device replacement,
firmware upgrade, and L-STAT configuration are performed with very little effort through
the controller. The L-STAT device is represented in the controller by a simple data point
interface, which can be directly connected to the IEC 61131 or IEC 61499 logic application
and offers all common functions for data points such as alarming, scheduling, trending,
historic filters, math functions, etc.
Using an NFC tag, the L-STAT transmits the URL of an L-WEB project to mobile devices
for more extensive control and administrative tasks. Last but not least, the L-STAT comes
with a built-in infrared receiver for comfortable remote control.

Are used to visualize data that is provided by the Modbus master and
that can be edited by the user. It is shown in DISPLAY-mode and it
can be edited in EDIT-mode. For the set point registers see Table 32
on Page 44 and Table 29 on Page 41 for set point configuration.
The range in which a set point can be altered is defined by minimum
and maximum values that have to be written by the Modbus master.
Please refer to Table 33 on Page 45 and Table 34 on Page 46.
Are used to add a certain offset to a display value. This functionality
can be used to calibrate sensor values. Offset values can be editet by
the system administrator in CALIBRATION-mode directly at the
device or over Modbus. Please see Table 35 on Page 47 for the
offset value register.
Figure 4: Operating Modes of L-STAT
When the device powers up, it enters DISPLAY-mode and it will display the first display
value. When pressing the MENU-button the next value will be shown. First all active
display values and then all active set points are displayed. After the last set point, the
display will show the first display value again.
EDIT-mode is entered by pressing the MENU-button for more than 3 seconds. To enter
EDIT-mode as system administrator two additionally defined buttons (TB0 and TB4) need
to be pressed along with the MENU-button for more than 3 seconds. The system
administrator will also be able to view and edit the device settings. In EDIT-mode any
button that has no specific function can be used to cycle the values in the opposite direction.
CALIBRATION-mode will be entered for any display value when pressing one UP- and
one DOWN-button simultaneously for more than 3 seconds to adjust the offset. This mode
is secured by the system administrator password. CALIBRATION-mode is left when
pressing the MENU-button for more than 3 second or after a timeout of 1 minute.

3 Modbus
3.1 Introduction
The L-STAT operates as a Modbus slave in Modbus RTU mode. The default baudrate is set
to 57600, the default parity is set to ‘none’ and the default address is set to 1. The
communication with a Modbus master device will work with Modbus function code 0x03
(Read Holding Registers). Section 3.4 shows all available Modbus registers.
3.2 Modbus Network
Figure 5 illustrates a typical Modbus network setup with a linear bus topology used to
connect several slave devices to a master device. The transmission line has to be terminated
at both ends. At the master device this can be done by connecting an L-Term (LT-04)
device. Each L-STAT slave device is equipped with a built-in 120Ω termination resistor.
Set the termination switch to OFF except on the last device on the bus where the termination
switch must be turned ON.

3.4 Modbus Register Description
In the following sections the L-STAT Modbus registers are described. Abbrevations are
explained at the end of each table. ‘R’ indicates that this value is not used by now and that it
is reserved for future use. Square brackets ‘[]’ indicate that this is the initial value. Numbers
with the prefix ‘0x’ are hexadecimal values. Values with no prefix indicate decimal values.
3.4.1 Data Registers
These registers contain data that is changing frequently. This data is not stored persistent in
the L-STAT device and will be lost after a reboot.

The present_state register always represents the actual state of the buttons and the
occupancy sensor.
The short_pressed and long_pressed states will remain set until the flags are cleared by the
Modbus master by writing a logical ‘1’ to the specific flag, except the occupancy flag that
is cleared automatically after the occupancy_timeout has expired.
Bits 0-11 indicate the states of the buttons (TBx-touch button, EBx-external button)
Occu: occupancy flag, defines if occupancy is detected by built-in occupancy sensor
(applies to LSTAT-801-Gx-Lx and LSTAT-802-Gx-Lx)
NFC: NFC flag, is set if an NFC field was detected. This gives the information that a
user is reading the NFC tag memory with an NFC enabled mobile device. For
more information see Chapter 4.
IRC: infrared remote control flag, is set when an infrared remote control code was
received. The received code can be read via the ir_remote_control_command
register at register address 32 (see Table 9 on Page 24).
SPC: Set point changed flag, is set when a set point was changed on the L-STAT.
Each set point has an individual change flag at register address 3 (see Table 8 on
Page 23).
DOC: device setting or offset value changed flag, is set when a device setting or offset
value was changed on the L-STAT. The specific change flags can be read via the
registers at address 4 and 5 (see Table 8 on Page 23).
ERR: error flag, is set when an internal error has occurred.
FD:
factory default (unconfigured) flag, is set when the device has booted with factory
default settings.
 Button states and flags can have the following binary values:
1 – pressed, set
0 – released, cleared
 The present_state register is only updated in DISPLAY-mode!

The following Table gives an overview of the internal sensor values. These registers can be
read over Modbus and can be used as source for a display value if configured. As described
in Section 2.2.2 on Page 15 there are up to 16 display values used to visualize data.
Each display value has two 16 bit configuration registers to specify the values displayed.
Display values (register address 64 to 79) are read- and writable over Modbus.

 A sensor value can be used as source for a display value. Therefor the DSSA or DSEU
bit as well as the semantic meaning at the corresponding display value configuration at
address 256 to 286 has to be set (see Table 28 on Page 39). If the DSSA or DSEU bit
is set this specifies that a sensor value is used instead of a display value. The semantic
meaning specifies which sensor value is used as source for displaying. For an overview
on this topic please see Figure 6 on Page 21.
 Sensor_value_0, sensor_value_1 and sensor_value_3 are 16 Bit signed values. All
other sensor values are defined as 16 Bit unsigned since there are no negative values to
expect. The values are scaled as described in Table 39 at Page 51.

 The DSSA or DSEU bit at the corresponding display value configuration at address
256 to 286 has to be cleared to display the content of a display value register (see
Table 28 on Page 39). If the DSSA or DSEU bit is cleared this specifies that a display
value is used instead of a sensor value. The semantic meaning specifies which text is
displayed along with the specific display value. For an overview on this topic please
see Figure 6 on Page 21.
 All registers are 16 Bit signed values. Depending on the modbus_unit specified with
the corresponding display value configuration register at address 256 to 287 (Table 28
at Page 39) the value needs to be scaled as described in Table 39 at Page 51 to achieve
the desired result.

registers for display values at address 256 to 289 and set points at address 320 to 351
to match the selected unit system. Please see Table 28 on Page 39 for display value
configuration and Table 29 on Page 41 for set point configuration.

These registers hold the configuration of the 16 display values.
semantic_meaning: is used to provide information about the semantic meaning and the
source of the value. For further information please see Table 30 on
Page 42.
CAL: if set to ‘1’ the corresponding offset_value can be edited in
CALIBRATION-mode (only capable if DSEU or DSSA is set to
‘1’)
unit_lstat: defines a unit with which the corresponding display value appears
on the LCD
unit_modbus: defines a unit that the corresponding display value register appeare
on Modbus
 For both, unit_lstat and unit_modbus the following values are possible:

Bits 0-11 of the higher address of each configuration register indicate the symbols that are
displayed along with the corresponding display value.
DSEU: display source for end user
DSSA: diplay source for system administrator
These two bits define if the value displayed is taken from a display_value register at address
64 to 79 (see Table 11 on Page 25) or from a sensor_value register at address 48 to 56 (see
Table 10 on Page 24). The following states are valid:
0 – defines that the value is taken from a display_value register that has to be set via
modbus
1 – defines that the value is taken from a sensor_value (+ offset_value) register that is
automatically updated with the current sensor value
VEU: visible for end user
VSA: Visible for system administrator
These two bits define if the display value is visible for the end user and/or the system
administrator. If set to ‘1’ the value will be visible.
 See Table 31 on Page 43 for example configurations of display values or set points.
* Please note that config_display_value_3 register is only configured as above per default
for LSTAT-802-Gx-Lx devices for displaying the actual CO2 level. Otherwise all bits of
this register are set to ‘0’.

These registers hold the configuration for the 16 set point.
semantic_meaning: is used to provide information about the semantic meaning of the set
point. For further information please see Table 30 on Page 42.
PIN: if set to ‘1’ the the corresponding set point is pincode protected
and can only be changed in EDIT-mode if the correct pincode has
been entered before.
unit_lstat: defines a unit with which the corresponding set point appears on
the LCD
unit_modbus: defines a unit that the corresponding set point register appears on
Modbus

Bits 0-11 of the higher address of each configuration register indicate the symbols that are
displayed along with the corresponding display value.
EEU: display source for end user
ESA: diplay source for system administrator
These two bits define if the set point is editable for the end user and/or the system
administrator. The following states are valid:
0 – defines that the set point is not editable
1 – defines that the set point is editable
VEU: visible for end user
VSA: Visible for system administrator
These two bits define if the set point is visible for the end user and/or the system administrator.
If set to ‘1’ the set point will be visible.
 See Table 31 on Page 43 for example configurations of display values or set points.

Table 30 below shows possible values for the semantic meaning used in the configuration
for display values (Table 28 on Page 39) and set points (Table 29 on Page 41).
Primarily the semantic meaning field defines a text that is displayed along with a display
value or a set point. Additionally for display values it defines the internal sensor_value that
is displayed when the DSEU or DSSA bit is set. For examples on how to use the semantic
meaning field in the configuratiuon registers please see Table 31 at Page 43 for example
configurations.

These registers are used to define offsets for display values when displaying a value from
a built in sensor. These registers can either be written via Modbus or can be edited in
CALIBRATION-mode by the system administrator.
All registers are 16 Bit signed values. Depending on the tepwi_unit specified with the
corresponding display value configuration register at address 256 to 287 (Table 28 at
Page 39) the value needs to be scaled the same as the corresponding display value as
described in Table 39 at Page 51.

Note that though a display value or a set point would accept values from 0 to 65535 if
unsigned or -32768 to 32767 if signed the value that is displayed is limited to a range from
-999 to 9999 because of the 4 digit display.
 When a fixed-point number reaches a certain limit where an overflow occurs the
decimal point is shifted rightwards (e.g. 999. 9 → 1000).
 Whole number values are preferably displayed with the bigger digits. If an overflow
occurs the number is shifted rightwards (e.g. 999 → 1000).

4 NFC
4.1 General Description
The NFC interface of the L-STAT device can be used to get additional information and
configuration options for room automation. The L-STAT will behave like an NFC tag that
can be read by an NFC enabled device. The antenna is located behind the LCD and best
performance is achieved by putting the NFC enabled device right on the front panel glass.
Depending on where the antenna of the mobile device is located the optimal position will be
found by moving the device slowly over the front panel. Best performance can be achieved
by positioning the device in a more or less horizontal position covering the LCD as shown
in Figure 8.
Figure 8: NFC Device Positioning
If the connection is established the NFC field detection bit at the short_pressed Modbus
register at address 1 (Table 7 at Page 22) will be set. In the meantime the NFC enabled
device will read the memory of the tag and will perform an appropriate action. Since a
NDEF URI record is saved at the tags memory (Table 38 at Page 50) the device will ask to
open the defined URL in the browser of the NFC enabled device.

5 IR-Remote Control Operation
5.1 General Description
The IR receiver is located behind the front panel glass above the LCD. The L-STAT device
implements the NEC IR protocol compatible with the Apple remote control as displayed in
Figure 11.
Figure 11: Apple Remote Control
Whenever a command gets received the IRC bit at the short_pressed Modbus register at
address 1 (Table 7 at Page 22) is set. The received button code as well as the remote ID can
be read from the ir_remote_control_command register at address 32 (Table 9 at Page 24).

5.2 Remote Control Pairing
Each remote control has an ID that is transmitted along with the button code. This ID can be
used to pair a certain remote control with a certain L-STAT device. The ID of the Apple
remote control can be changed by pressing Menu and Center button for at least 6s. This will
increment the ID by one.
The ID of your remote control can be checked by pressing any button and watching the
ir_remote_control_command register in the Web interface as shown in Figure 12 below.
This example shows that the Menu button was pressed on a remote control with the ID 14.
Figure 12: IR Remote Control Command Register
If an L-STAT device gets paired with a certain remote control it will only update the
ir_remote_control_command register and the IRC bit at the short_pressed register when
receiving a command from this remote control. So an L-STAT device can only be paired
with one remote control but a remote control can be used for multiple L-STAT devices.
Pairing can be achieved by pressing Menu and Right button at the remote control for at least
6s while pointing towards the L-STAT device. If pairing worked the secondary display will
shortly show ‘IRP’ (IR pairing). The remote ID will be saved internally and the IRCP flag of
the config_flags register at address 192 (Table 22 at Page 33) will be set.
The pairing can be canceled by either clearing the IRCP flag or by pressing Menu and Left
button for at least 6s. If the secondary display shows ‘IRUP’ (IR unpairing) shortly the pairing
is suspended.
