4. Connectors & LED indicators
The location of the connectors is shown in the figure below ;
The following indicators show the status of the controller :
•Relay (green) – this LED is illuminated whenever the relay is closed (the ormally
Open contact is closed and the ormally Closed contact is open);
•Power (red) – this LED flashes when the power supply is turned on;
•Busy (yellow) – this LED indicates that someone is connected to the controller
through web interface;
• Link (green) – this LED is located on the Ethernet connector. It indicates that the
device is connected to the network ;
•Act (yellow) – this LED is located on the Ethernet connector. It flashes when activity
is detected on the network.

5. Application e amples
5.1 Remote control
The controlled device is connected in series with the relay contact. Users can operate
TCW110 using a web browser or by using custom S MP applications.
5.2 Remote monitoring
A relay output from the monitored device is connected to digital input of TCW110.
When an event occurs – the controller sends an E-mail message to a predefined e-mail
address. S MP Trap message is sent if custom S MP monitoring software is used.

6. Installation
Please follow the steps below for proper installation :
1. Mount the controller in a dry and ventilated place.
2. Connect the Ethernet port to a 10/100 Base T Ethernet connection. For direct
connection to a PC use a “crossover” cable.
3. Connect the I/O pins of the controller according to the required application.
4. Connect the power supply.
If the Power LED is blinking, it indicates that the power supply is OK. By default TCW110
comes with the following network settings:
IP:192.168.1.2 , Subnet Mask: 255.255.255.0 , Default Gateway: 192.168.1.1
Communication with TCW110 may be established by assigning a temporary IP address to
your computer that is on the same network (for example 192.168.1.5). To get access to the web
interface of the controller, you should type the following URL into the browser :
http://192.168.1.2 . If the network settings are correct, the “Login” page will appear.
7. Web-based setup
The web interface allows the TCW110 to be configured, controlled and monitored via web
browser. Recommended programs are Mozilla Firefox, Chrome and Internet Explorer 6 (or higher
version) at 1024x768 resolution.
7.1 Login age
After opening the Login page, authorization data must be entered ( by default
username=admin , password=admin). It is recommended to change the username and password
to prevent unauthorized access to the controller.
Depending on the username and password, there are two access levels to the controller -
user and administrator. This is done to restrict the access to certain functions. Both access levels
are described in table below :
administrator user
Account Administration
Monitoring
etwork Setup
I/O Setup
S MP Setup

The controller supports only one active session – only one user (administrator) can operate
the device. If another user tries to login, the following message appears: “Someone’s logged in”
The active session will be terminated automatically, if the current user stays inactive for 2
minutes.
7.2 Monitoring age
After successful authorization, the Monitoring page appears:
The Monitoring page provides information about the state of the digital and analog inputs,
relay state and the temperature (if temperature sensor is connected to the controller) .
7.3 I/O setu age
The input and output settings are made in “I/O Setup” page. The following parameters can
be set :
•Descri tion – brief description of the output, maximum 11 characters should be used.
•Pulse Duration – time for which the relay changes its state, by pushing the "Pulse" button
on "Monitoring" page.
•ICMP Mode – this is an operational mode, in which the controller restarts the relay
output, if no ICMP echo-request (ping) is received from specified IP Address for
specified time (Ping timeout for restart ) .
•Ping time out for restart – timeout for restart for Relay 1 .
•IP address - IP address of the host from which ping is expected.

•Maximum number of restarts – maximum number of restarts after timeout for restart
has expired
In the configuration example above, the controller expects ping from host with IP Address
192.168.32.103. If, within 5 seconds the controller receives no ping, the Relay will be restarted
for a period of 2 seconds, as the maximum number of consecutive restarts is limited to 5.
One of the possibilities of TCW110 is to send e-mail messages when the status of the digital
input Digital In ut 1 is changed. To do this, the following parameters must be set:
•Descri tion – brief description of the input, maximum 11 characters should be used.
•Subject – message subject, maximum 11 characters should be used
•Message – message body, maximum 22 characters should be used
In the example above, if an event occurs (closing contact) the controller will send e-mail
message to [e-mail] with subject: “Alarm” and the text:”Alarm is activated” .
Im ortant! It is necessary to set SMTP server settings on " etwork Setup" page, to
successfully send e-mail messages.
Only the field “Description” can be changed for the Analog In ut 1. Maximum 11 characters
may be used.

7.4 Network Setu age
The etwork parameters are set on this page. The following parameters can be changed:
•IP configuration – IP Address configuration can be static or dynamic (DHCP)
•IP address, Subnet mask , Default gateway – these fields are active if IP address is
static
•Host Name
•MAC – device MAC address
If multiply TCW110 controllers are used on the same network, please change the IP address
after connecting the device to the network. This will avoid devices installed on the network with
the same factory default IP address at the same time. It may be necessary to clear the arp cache
each time you connect new device to the network. This is done by typing arp -d in the command
prompt of a Windows computer.
In order to reduce network traffic and to limit the access, the controller supports VLA and
MAC address filtering. In addition to the MAC address of the Default Gateway, another 2 MAC
addresses can be added to the filter. The filter is enabled by marking the appropriate check box
after the MAC address.
To set up the SMTP server the following fields should be completed
•Mailserver IP – IP address of SMTP mail server, note that TCW110 don’t support SMTP
authentication
•E-mail – sender e-mail

7.5 SNMP Setu age
TCW110 supports S MP v.1 that enables trap delivery to an S MP management
application. This enables the device to be part of large monitoring and control networks. The
possible settings are:
•SNMP Configuration – enable S MP v.1
•Read-Write community – performs client authentication
•Read-Only community – performs client authentication
S MP trap messages are sent for the following conditions:
-when event occurs on Digital In ut 1 (the signal changes its state)
-measured voltage on Analog In ut 1 is outside the predefined range
-measured temperature Is outside the predefined range
-restart
Setting range for sending S MP trap messages is done only through S MP. The following
parameters can be changed:
•SNMP Tra s – enable S MP trap messages
•IP address – IP address of the receiving host
•Community string – performs client authentication
•Tra Interval - time interval for S MP trap messages
•Max. number of Tra s – maximum number of S MP trap messages sent, if trap
condition is present

8. Control and monitoring using SNMP
TCW110 can be configured and monitored through S MP (Simple etwork
Management Protocol). This could be done using every S MP v.1 compatible program.
Parameters that can be changed, are grouped according to their functions in the tables below.
To obtain a valid OID number it is necessary to replace the “x” symbol with the prefix
”.1.3.6.1.4.1.17095”. To save the changes you should set a value ”1” of the
configurationSaved (OID x.8.0).

9. Restoring Factory Default Settings
If the IP address or password are forgotten, TCW110 can be restored to its original
factory default settings. To do this, please follow the steps below:
- remove the power supply from the unit and open the plastic box
- press and hold the RESET button then turn on the power supply
- The leds POWER and BUSY are flashing 12 times, after that they will turn on. In this
moment the RESET button should be released. The factory default settings are
shown in the table below:
User Name (Admin) admin
Password (Admin) admin
