1 Introduction
The TP Touch Point is a moderncomfort management wallpanel with two most popular
open communicationprotocols: ModbusRTU/ASCII and BACnetMS/TP.The Touch Point
is available in different configurations of sensors (temperature, CO2, and humidity), colors,
and versions with or without a display. The panel is equipped with an interactive TFT
touchscreen, touch buttons, and glass panel.
The panel can be configured using the iSMA Configurator software or Modbus registers/
BACnet objects. It fits most of standard junction boxes in Europe and can easily be
installed using a wall back box.

2 Communication Protocols
The TP panel supports Modbus RTU/ASCII and BACnet MS/TP communication protocols,
using 2 RJ45 sockets and a screw terminal (one RS485 port).
Note: A communication protocol is selected by setting a second switch on the DIP switch
on the back of the panel:
Off: Modbus RTU/ASCII (default);
On: BACnet MS/TP.
The Modbus address of a server device is set using the rotary switch.
Note: If the rotary switch is set to 0, the address is read from the ADDRESS register/object
(decimal address: 22). See Communication Parameters.
Other communication parameters such as baud rate, number of data/stop bits, or parity
bit are set using relevant Modbus registers or BACnet objects.
2.1 RS485 Connection
Figure 1. RS485 communication diagram
2.2 RS485 Network Termination
Transmission line effects often present a problem for data communication networks.
These problems include reflections and signal attenuation. To eliminate the presence of
reflections of signal from the end of the cable, the cable must be terminated at both ends
with a resistor across the line adequate to its characteristic impedance. Both ends must
be terminated since the propagation is bidirectional. In case of an RS485 twisted pair
cable this termination is typically 120 Ω.
Note: A termination resistor can be added with a third switch on the DIP switch on the
back of the panel:
off: termination resistor disconnected (default);
on: termination resistor added.

3 Communication Parameters
The TP panel is capable of simultaneously exchanging data on two buses, RS485 and USB.
3.1 RS485
The RS485 bus is accessible with RJ45 or 4-pin green screw connector.
There are 3 communication protocols that can be selected using the DIP switch 2 and
PROTOCOL field:
DIP Switch 2 PROTOCOL (23)
Modbus RTU Off 0
Modbus ASCII Off 1
BACnet MS/TP On N/A
Table 2. Setting communication protocol
The Modbus register reading the protocol set on the DIP switch is the following:
PROTOCOL_DIPSWITCH: reads the communication protocol set on the DIP switch;
Modbus register: 30003;
BACnet object: N/A.
3.1.1 Setting MAC Address
The device's MAC address can be set using one of the following methods:
rotary switch: sets addresses from 1-9; if 0:
ADDRESS (decimal address: 22).
The Modbus register reading the address set on the rotary switch is the following:
ADDRESS_ROTARY_SWITCH:reads the Modbus address set on the rotary switch (0
means the address is read from the ADDRESS register/object);
Modbus register: 30002;
BACnet object: N/A.
3.1.2 Setting Communication Parameters
BACNET_DEVICE_ID: sets the device's BACnet ID;
Modbus register: 40015;
BACnet object: DEVICE, property: Object Identifier;
BAUD_RATE:sets a baud rate of the panel. The baud rate is calculated according to the
formula: baud rate = (register's value)⋅10. The default value is 11520 (115200 bps);
Modbus register 40017;
BACnet object: DEVICE, property: 3084.

of 1, 8, and none, respectively. Therefore, the user settings for these objects are not
applicable.
REPLAY_DELAY:determines a number of milliseconds before the panel answers the
request. This time is used to extend the interval between the request and response. The
default value of 0 means no delay (the response is sent once during the 3,5 character
required by the Modbus RTU protocol).
Modbus register 40021;
BACnet object: N/A.
Incoming data frames are counted and presented through the following parameters:
RECEIVED_FRAMES: shows the number of received frames. The register's value is reset at
the start of the panel and at the change of transmission parameters;

•
•
WARNING!
The above parameters are remembered, but NOT automatically set. In order to set
these parameters to the panel, it is required to perform one of the following actions
after entering required values:
restart the panel;
send a reload settings command (0: 0x2FF, DEVICE (property: 3030): 0x2FF, iSMA
Configurator, or FCU Updater).

BACnet object: AI4, property: 4205;
TEMPERATURE_FILTER:allows to set a filtering value for the temperature sensor
(expressed in seconds). The default value is 2 seconds;
Modbus register: 40307;
BACnet object: AI4, property: 4003.
5.2 Humidity Sensor (Optional)
A humidity sensor is an optional equipment in the TP panel. It is marked with a letter H in
a product code, for example: TP-H (means the panel is equipped with a temperature
sensor and humidity sensor).The humidity sensor's configuration data is available in the
following parameters or in the iSMA Configurator:

HUMIDITY_SENSOR:indicates a current humidity value with offset;
Modbus register: 30302;
BACnet object: AI5, property: Present Value;
HUMIDITY_SENSOR_OFFSET:allows to set an offset value for the humidity sensor
(correction to the humidity sensor's value). The default value is 0;
Modbus register: 40305;
BACnet object: AI5, property: 4205;
HUMIDITY_FILTER:allows to set a filtering value for the humidity sensor (expressed in
seconds). The default value is 2 seconds.
Modbus register: 40308;
BACnet object: AI5, property: 4205.
5.3 CO2 Sensor (Optional)
A CO2 sensor is an optional equipment in the TP panel. It is marked with a letter C in a
product code, for example: TP-C (means the panel is equipped with a temperature sensor
and CO2 sensor).The CO2 sensor's configuration data is available in the following
parameters or in the iSMA Configurator:
CO2_SENSOR: indicates a current CO2 value with offset;
Modbus register: 30303;
BACnet object: AI6, property: Present Value;
CO2_OFFSET:allows to set an offset value for the CO2 sensor (correction to the CO2
sensor's value). The default value is 0;
Modbus register: 40306;
BACnet object: AI6, property: 4205;
CO2_FILTER:allows to set a filtering value for the CO2 sensor (expressed in seconds). The
default value is 2 seconds;
Modbus register: 40309;
BACnet object: AI6, property: 4003.
5.4 Temperature Setpoint
The TP panel has a feature of setting a temperature setpoint and sending it through
communication protocols to any temperature control device. The temperature setpoint
value is configurable through the following parameters or in the iSMA Configurator:
EFFECTIVE_SETPOINT:indicates a sum of the temperature actual setpoint value and
offset. The register contains a value multiplied by 10;
Modbus register: 41502;
BACnet object: AI3, property: Present Value;
SETPOINT_VALUE:allows to set an actual temperature setpoint value. After reset, the
DEFAULT_SETPOINT register's value is set to the SETPOINT_VALUE register. The register
contains a value multiplied by 10. The value range is 0-500 (0-50oC);
Modbus register: 41501;
