Summary of Contents for Teracom TCW280

  • Page 2: Short Description

    – DC motor control, LED dimming, etc. The frequency in PWM mode can be up to 2 kHz. TCW280 has also 2 relays with normally closed and normally open contacts. Both relays can be activated from the WEB interface, M2M protocol or by the schedule.

  • Page 3: Specifications

    4. Specifications • Physical characteristics Dimensions: 115 x 90 x 40 mm Weight: 170 g Mounting: wall and DIN rail • Environmental limits Operating Temperature: -10 to 55°C Storage Temperature: -20 to 70°C Ambient Relative Humidity: 10 to 80% (non-condensing) •...

  • Page 4: Installation And Setup

    Appendix A, this provides ventilation and electrical isolation TCW280 can be mounted to a standard (35mm by 7.55mm) DIN rail. Attach the controller to the DIN rail by hooking the hook on the back of the enclosure to the DIN rail and then snap the bottom hook into place.

  • Page 5: Power Supply Connection

    Pin3 – VOUT2 5.3.1. Power supply connection TCW280 is designed to be supplied by adapter SYS1308-2412-W2E or similar, intended for use in the conditions of overvoltage category II. The power supply equipment shall be resistant to short circuit and overload in a secondary circuit.

  • Page 6: Open Drain Outputs

    5.3.3. Open drain outputs TCW280 has four isolated open drains (digital) outputs. Every digital output can be programmed to work either in ON/OFF or PWM (Pulse-width modulation) mode. In PWM mode a few frequencies are supported. The working frequency of PWM has to be higher than the effect which is expected in the load.
  • Page 7 The output schematic is as follows: The open drain outputs in PWM mode can be used for control dimming of LEDs, speed control of PMDC motor, control the angle of servo motors, etc. The open drain outputs in ON/OFF mode can be used as a standard digital output. They can control directly the “dry contact”...

  • Page 8: Network Connection

    5.3.4. Relays connection TCW280 has 2 relays. They can be used for switching on or off electrical and electronic devices. The relay contacts are internally connected directly to the terminal connectors. For both relays normally open, normally closed and common contacts are available. For loads with higher switchable current/voltage than specified, an external relay should be used.

  • Page 9: Communication Setup

    TCW280 can be used in a wireless network by connecting through a wireless router. 5.4. Communication setup By default TCW280 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 TCW280 can be established by assigning a temporary IP address to the computer.

  • Page 10: Web Interface

    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.
  • Page 11 6.1.1. Analog outputs section This section contains information about the current state of each analog output as well as its operating range. Entering a new value and pressing "Set" button changes the status of the output. There is protection against entering values outside the selected range. The selected output value is stored in non-volatile memory, and after a power-restore cycle, it is automatically set.

  • Page 12: Digital Outputs

    For locally activated relays a text description of the controlling parameter is displayed rather than buttons. The local relay activation can be set in “Setup->Outputs”. 6.2. Setup 6.2.1. Network The network parameters are set on this page. The controller supports static and dynamic IP addresses. It is good practice to change the default IP address of the controller immediately after first power- on.
  • Page 13 Here you set the operating mode for each output, its operating range, and the value after power on. By default, it is the last remembered one. For PWM mode, the frequency can be selected from a drop-down menu, but it is the same for all outputs.
  • Page 14 6.2.3.4. Monitoring page automatic refresh Monitoring page refresh interval can be set between 0 and 253 seconds. Zero means no automatic refresh. 6.2.3.5. Display All three sections on Monitoring page can be added/removed independently by appropriate setup here. 6.2.4. Time For proper operation of schedules, there is an internal real-time clock (RTC).
  • Page 15 6.3. Services 6.3.1. Modbus TCW280 supports Modbus TCP/IP. By default Modbus is disabled. Standard port for this protocol is 502. More about this functionality can be read at MODBUS section below. 6.3.2. SNMP TCW280 supports SNMP v.2. In this section, all necessary parameters for proper operation of SNMP can be set.
  • Page 16 6.3.3. HTTP Post TCW280 can periodically upload a file to a dedicated server, using HTTP Post. The period of the post is between 10 and 3600 seconds. The file format can be XML or JSON. In addition to the periodical post, the file can be uploaded at any alarm condition. In this case “Connect on any alarm”...

  • Page 17: Dynamic Dns

    The username and password can be up to 31 characters long. 6.4.2. Backup/Restore The TCW280 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.
  • Page 18 Attention! Don’t turn off the power supply during the update. Turning off the power supply will damage the device. 6.5. Logout The TCW280 support multisession, but the good practice is to log out after finishing the work. TCW280_R1.2 – February 2019 Page 18...
  • Page 19 LAN. Each controlled device, at all times, executes a software component called an agent which reports information via SNMP to the manager. The TCW280 can be configured and monitored through SNMP. This could be done using every SNMP v.2 compatible program. Parameters that can be changed, are grouped according to their functions in the tables below.
