General description
The Tx5xx devices are designed for measurement of temperature, dew point and humidity.
Measured value can be displayed on the instrument LCD display, or it is possible to read it out by
means of an Ethernet interface (to be subsequently processed in a PC). The following formats are
supported:
• www pages with user-design possibility
• modbus protocol
• snmp protocol
The instrument may send a warning message to several defined points if the measured value
gets out of adjusted limits. There are the following possible ways to deliver the warning report:
• to send an e-mail to maximum of three e-mail addresses
• to send a snmp trap to maximum of three IP addresses
• to display an alarm state on the device www page
Alarm limits may be set via modbus, telnet or a SNMP MIB table. The alarm state may be
read via the device www pages, the information console or the SNMP MIB table. A block diagram
of the device connection with to the PC is in Figure 1.
Figure 1- block diagram of the connection
Preparation to operation
In order to be able to use all the features of the device it is necessary to do some settings by
means of a PC. In the case of T4511 transducer it is necessary to connect a temperature probe
before use (see chapter Installation, page 7).
What is needed to operate instrument
• ac/dc adapter 9-30V, 200mA (more details - see chapter Power voltage page 7)
• RJ-45 LAN connection
• free IP address in your network
• temperature probe with a Pt1000 sensor for the T4511 transducer
Contact network administrator to get free IP address
Warning! Safety reception of warning messages (e-mail, trap) depends on actual accessability of
required network services. It is recommended to protect device against the unauthorized access to
device settings and connection of cables.

Power voltage
Power voltage: 9 to 30Vdc, maximum consumption 200mA, connector coaxial, diameter
5 x 2.1 mm, positive pole is the central pole.
Installation
It is necessary to assign a new suitable IP address to the device at the first connection to it in
order to prevent collisions with already existing network IP addresses, and make the address
conform with the local habits. If installing several new devices, connect them to the network one
after another! If a suitable IP address is not known, contact your network administrator and ask him
for the following:
IP address: _____._____._____._____
IP gate address: _____._____._____._____
Mask of network: _____._____._____._____
The IP gate address and the network mask need not be specified if the device will be
operated only in a local network. If you set the IP address to one which is already used in the
network the device will not work correctly and collisions in the network will appear.
The IP address of each device is set by the manufacturer to 192.168.1.213.
Installation procedure
• run a Tx5xx_setup.exe
• set a new IP address of the device (default IP address is 192.168.1.213)
• configure the device in accordance with your requirements (alarm settings, sending of e-
mail, traps…)
• store the settings
See more details about use of the Setup in chapter Setting of device – Setup, page 17.
IE-SNC-Tx5xx-03 8
Checking operation
Visual check
After connecting the power supply the LCD displays a currently measured value (if the LCD
has not been switched off). If the measured value exceeds the measuring range of the temperature
probe or the temperature probe is not connected correctly Err 1 or Err 2 reading appears on the
LCD. In this case check the temperature probe connection and that the value being measured is in
the allowed measuring range. (Connection of the temperature probe is relevant only for the T4511
transducer).
Communication check via a LAN
Open a browser of www pages and enter the device IP address.
Example: http://192.168.1.213
The device displays its name, serial number, measured values, alarm states and alarm
settings (Figure 5). If „Access denied“ appears instead, the display of www pages is not allowed
(Figure 10). (Change the appropriate setting in the Setup - more details in chapter WWW- WWW
configuration, page 20).
Figure 5 – device www pages
Calibration
Recommended calibration interval is
• one year for T3511
IE-SNC-Tx5xx-03 9
• two years for T4511
Storing
Store the device in a temperature range of -30 to +80 °C, non condensing humidity 0 to 99 %RH.
Description of device functions
Information provided by the device can be read on its LCD display or by means of the
following protocols. To communicate via SNMP and modbus protocols it is necessary to have
appropriate software installed on the computer. Such software is not included in the delivery.
The following part describes functions and features of the device.
Alarms
It is possible to set an upper limit, lower limit, hysteresis and time delay to each measured
value.
Description of alarm function
Figure 6 shows a temperature curve with some specified upper limit (temp_limit_high) and
hysteresis. At point 1 temperature exceeds the limit. From that moment a time delay is counted
(time_delay) after which an alarm is set. Because at point 2 the temperature dropped below the
limit value (temp_limit_limit) before the time delay expired, alarm was not set.
Figure 6 – temperature curve
At point 3 the temperature again exceeded the limit, and because it did not drop below the
limit value (temp_limit_high) before the time delay ended, the alarm was set at point 4. At this
moment the alarm e-mails and traps are sent, if they are enabled, and the alarm flag is set (the flag is
set when the alarm is active and reset when inactive). The state of the flag can be found on the
www pages or via Modbus or the information console. The alarm lasted to point 5, where the
temperature dropped below the limit value given by the adjusted hysteresis (temp_limit_high–
hysteresis).
For other measured values the principle of alarm activity is analogical.
An alarm report is always sent right after an alarm appears. The device memorizes sent
alarm reports of current alarms while the power is connected. In case of power disconnection or a
IE-SNC-Tx5xx-03 10
reset of the device (e.g. by modification of configuration) a new alarm evaluation is performed and
new alarm reports are sent again, if any.
It is possible to set the alarm parameters via telnet, modbus protocol or a SNMP MIB table.
Detailed description of setting via these protocols can be found in chapters informing about
particular services.
Modbus
The device contains support for the Modbus protocol to communicate with control systems.
The protocol runs in the RTU mode. The port is set to 501 (for more details about the Setup see
chapter Setting of device – Setup, page 17). The modbus address of the device is always set to 1.
Port 501 enables full access, i.e. both read and write operations are supported. Access to
port can be disabled in the Setup.
Supported Modbus commands:

• Ascii character
Temperature, RH and DP alarm states can have the following values:
• no value is inside of adjusted limits
• lo value is lower than adjusted limit
• hi value is higher than adjusted limit
Registers can be read one by one. But it is necessary to write all 15 values to the memory
0x5001 – 0x500F together as a block (alarm states are not affected).
SMTP
In case of exceeding adjusted limits of measured values the device can send e-mails to
maximum of three addresses. Maximum length of an e-mail address is 55 characters. It is necessary
to set your SMTP server address for correct function of e-mail sending. Procedure how to set SMTP
is described in chapter Setting.
If limits of several measured values are exceeded a special alarm e-mail is sent for each
alarm state.
Dummy address sensor@[device IP address] is displayed as a sender of the email. It is not possible to reply to this address. In the Subject field of the message the sentence
Alarm [Description of the device]* is displayed or Test message
[Description of the device] in the case of sending a test e-mail.
*[Description of the device] can be entered in the Setup (chapter Global settings, page 19)
The description of the device is preset to the string TRh-Sensor, or T-Sensor depending
on the device model. Figure 7 shows a message reporting exceeding the temperature limit.
IE-SNC-Tx5xx-03 12
Figure 7 – example of an e-mail from the device reporting exceeding of temperature limit
Format of the message:
• Information report
• Temperature overflow – temperature limit exceeded
• Humidity overflow – humidity limit exceeded
• Dew point overflow – dew point temperature limit exceeded
• Currently measured value at the time when the alarm was raised
• Current setting of alarm limits.
• For actual info please visit http://[IP device]. Have a nice day – for actual
information please visit www pages of the device at address http://[IP address
device].
SNMP
By means of the SNMP protocol it is possible to find currently measured values, read and
set parameters concerning alarms. In case of alarm activation, warning message (a trap) can be sent
to specified addresses. By means of the SNMP MIB table it is also possible to display history of last
100 measured values.
For read and write the device communicates via port 161. Traps are sent via port 162.
Sending of traps can be disabled in the Setup.
The following traps sent:
0/0 reset of the device
1/0 testing trap
6/3 report on a measured value being outside of the limits or a return of the measured value to
the limits
IE-SNC-Tx5xx-03 13
For the correct function of the SNMP server it is necessary to store the MIB table RFC-
1213.mib and Tx5xx.mib to the client MIB. The path to the device is then:
iso.org.dod.internet.private.enterprises.comet.products.tx5xx.
MIB tables are available at www pages http://www.cometsystem.cz or on the installation CD in the
MIB directory.

• 1 upper limit exceeded
• 2 lower limit exceeded
Password for a read operation is set by the manufacturer to PUBLIC, password for write is
set to PRIVATE. These passwords may be changed in the setup.
History
By means of the MIB table it is possible to display history of the last 100 measured values,
stored in adjusted time interval. This interval is set in the Setup (chapter SNMP- Trap
Configuration, page 20). If a value has not been measured yet or an error was detected the value is
9999. The history is erased after each restart of the device.
WWW
The device supports display of measured values, adjusted limits and alarm states on its www
pages. The address of the www pages is identical with its IP address. There are the two modes
supported:
• text version
• user-defined web (Graphics web)
IE-SNC-Tx5xx-03 15
In the user-defined web is possible show the history graphs, including pictures and upload
self-made web to device. More info about user-defined web you can find on http://cometsystem.cz
section programs. You can switch between this modes in setup. The demo of user-defined web is
showed on picture 8-b.
The web address is the same like the device IP.
Example: The device has an IP address 192.168.1.204. Enter http://192.168.1.204 to the browser
address field and confirm it with the Enter key. If your setup enables display of www pages
and the user-defined web is disabled, page will be displayed as in Figure 8-a.

The next informations are displayed as N/A. This problem will be occurred, when the device IP is
set to another LAN.
In Tx5xx_Setup.exe program choose Tools/Change device IP.
Figure 15- Change device IP address
Press the “Find device” button, in new created window select your unconectable sensor. IP and
MAC address will be displayed in Change Device IP address window. Enter the new sensor IP
address to New device IP address field. Be ensure, that the new IP address is unused, and press the
“Set IP” button.
The sensor IP address in Find device window is not displayed
In program Tx5xx_Setup. exe Select Tools/Change device IP. In change Device IP address (Fig.

format xx-xx-xx-xx-xx-xx ( e.g. 00-20-4A-84-F0-80) and press the “Set IP” button.
Finding the MAC address
The MAC address is a unique address of a device which is necessary to be known e.g. in
case when there are several devices connected to the network. Procedure:
• disconnect the device power supply
• unscrew four screws holding the lid
• remove the lid
• there is a number in the format 00-20-xx-xx-xx-xx on the network connector label below the
bar code. This is the MAC address of the device which is necessary to be known if the
device IP address is not known.
It is not possible to find meter after manual MAC enter
In program Tx5xx_Setup.exe menu select Tools/Change device IP. In this window ( Fig. 15)
select “Manual MAC enter” and “Set IP to ARP only”. To “Device MAC address” enter the meter
MAC address (e.g. 00-20-4A-84-F0-80) and press the “Set IP” button.
Open telnet to the IP address you assigned to the device MAC address by running a telnet
command telnet [IP_address_assigned_to_MAC_address] 9999 and confirm with
the Enter key.
Example: telnet 192.168.1.254 9999 and Enter. After the welcome message
