  • Page 10: Communication Setup

    TCW220 can be used in a wireless network by connecting through a wireless router. 6.3. Communication setup By default TCW220 is delivered with the following network settings: IP address: 192.168.1.2, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.1 Communication with TCW220 can be established by assigning a temporary IP address to the computer.
  • Page 11 This address should be on the same network - for example 192.168.1.3: To get access to the web interface, you should type http://192.168.1.2 into the browser. If the network settings are correct, the login pop-up window will appear: All TCW controllers connected to LAN can be easily found by the free tool “TCW discoverer”. It is available for Win and Mac operating systems and can be downloaded from www.teracomsystems.com TCW220_R4.15 –...

    ID number. For every sensor, there are a description, value, and ID information. Teracom 1-Wire sensors readings are shown in the Value 1 column. Dual sensors such as (TSH2xx) temperature/humidity sensors have the 2nd parameter shown in the Value 2 column.
  • Page 13 This option is very useful when TCW220 is used as a part of monitoring and control system managed either by SNMP or HTTP API commands. For some sensors “Unit”, “Multiplier” and “Offset” can be set in section “Setup-Input/Output”.
  • Page 14 For every analog input “Unit”, “Multiplier” and “Offset” can be set in section “Setup- >Input/Output”. 7.1.4. Data - relays section The section displays the current state of relays and presents buttons that can be used to change their status. Each relay can be activated either remotely by WEB, SNMP, HTTP API, and MODBUS or locally, from the status of a monitored parameter (1 Wire sensor, analog voltage, and dry contact).

  • Page 15: Smtp Setup

    There is a button for server settings test with feedback. In this test sender and recipient of the e-mail are the same. Transport Layer Security protocol is used for secure communication with public mail servers. TCW220 supports TLS 1.0, TLS 1.1, and TLS 1.2 with RSA as a key exchange/agreement and TCW220_R4.15 – November 2022 Page 15...

Conditions This section is used for parameterization of the trigger and alert conditions for 1-Wire sensors, analog inputs, virtual items and digital inputs. 7.2.4.1. 1-Wire sensors, analog inputs and virtual items For every sensor two type of fields are presented – one is for setup of trigger conditions (“Min”, “Max”...
  • Page 20 Example: TCW220, TST100, and appropriate heater are used to control the room temperature. The wanted minimum temperature is 19°C. The initial temperature is 17°C. TST100 is assigned to the first position for 1-Wire sensors. For Relay1 local activation from Sensor1 is set.
  • Page 21 The “Max” value is set far enough from the wanted temperature to avoid trigger/alert conditions around it. For every sensor or analog input, there are 3 independent ways of alert when there is an alarm condition – e-mail, SNMP trap, and post (HTTP/HTTPS post of XML file). Each alarm notification method is activated by checkbox.
  • Page 22 These options can be used for additional debouncing. On the picture above low-to-high and high-to-low delays are set to 0.1 seconds. 7.2.5. System On this page, some general settings can be made. 7.2.5.1. WEB access In this section, WEB access authentication can be deactivated. By default, it is activated with admin/admin authentication details.
  • Page 23 12 hours. 7.3. Services 7.3.1. Modbus TCW220 supports Modbus TCP/IP over the Ethernet interface. By default Modbus is disabled. Standard port for this protocol is 502. The table with the registers addresses can be found in section 8.3. MODBUS TCP/IP.
  • Page 24 Actual MIB file can be downloaded from here. 7.3.2. Logger The TCW220 supports logger for all monitored parameters and status of relays. The logger works in three modes – Time, Alarm and Time&Alarm. The mode specifies what initiates a record in the logger’s memory.
  • Page 25 More about the logger can be found in the Data logger section. 7.3.3. HTTP post TCW220 can periodically upload a file to a dedicated server using HTTP or HTTPS Post. The HTTPS is over TLS 1.0, TLS 1.1 and TLS 1.2 with RSA as a key exchange/agreement and authentication.
  • Page 26 The user and password can be up to 31 characters long. 7.4.2. Backup/Restore The TCW220 supports backup and restore of all user setting. All settings are saved in XML backup file. This file can be used after this for restore on many devices. This is very useful for multiplying similar settings to a batch of controllers.
