  • Page 2 Ethernet I/O module TCW241 1. Introduction TCW241 is an Ethernet IO module, the right choice for factory automation and distributed process control. It has 4 digital inputs, 4 analog inputs and 4 relays with normally open and normally closed contacts.

  • Page 3: Specifications

    3. Applications TCW241 is suitable for environmental monitoring and local control of an electrical and non-electrical parameter, industrial and building automation, data acquisition systems, general remote control, and monitoring. It works very well as a standalone device that can be controlled using a web browser or as a part of small and medium industrial control systems for SCADA (supervisory control and data acquisition).

    Appendix A, this provides ventilation and electrical isolation TCW241 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 6: Power Supply Connection

    Pin3 – 1-Wire +VDD 6.2.1. Power supply connection TCW241 is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for use in the conditions of overvoltage category II, and prior assessed for compliance with safety requirements. The power supply equipment shall be resistant to short circuit and overload in a secondary circuit.

  • Page 7: Digital Inputs Connection

    6.2.3. Analog inputs connection Attention! Analog inputs are NOT galvanic isolated. Analog inputs of TCW241 can be used for monitoring of DC voltage up to 60VDC. They can be connected directly to batteries, solar panels, power supplies etc. Built-in functionality “Multiplier”, “Offset” and “Dimension” for every analog input gives a possibility to monitor sensors with analog outputs and see directly a measured parameter.

  • Page 8: Sensor Connection

    6.2.4. Sensor connection Up to eight 1-Wire sensors can be connected to TCW241. The device supports following sensors - temperature, temperature/humidity, CO2, DC current, AC current, 4/20mA, galvanic isolated analog voltage, barometric pressure etc. Connected sensors are automatically detected and appropriate dimension is assigned.

  • Page 9: Relay Connection

    Although functionality has been achieved on longer distance, we cannot guarantee error-free operation over mentioned wiring length. guarantee proper operation only with Teracom 1-Wire sensors. 6.2.5. Relay connection The relay contacts are internally connected directly to the terminal connectors. For all relays normally open, normally closed and common contacts are available.

  • Page 10: Network Connection

    6.2.6. Network connection The Ethernet port of TCW241 should be connected to 10/100 Base-T Ethernet hub, switch or router. For configuration, TCW241 may be connected directly to the Ethernet port on a computer. The device support and it is not necessary to use “crossover” cable, standard “straight- Auto-MDIX through”...

  • Page 12: Web Interface

    The controller supports a few active session. 7.1. Monitoring page Monitoring page displays the current state of TCW241. The page has 4 sections – “Sensors”, “Digital inputs”, “Analog inputs” and “Relays”. All they can be added/removed from monitoring page independently by appropriate setup - see “Setup-System- Display”...
  • Page 13 If all sensors are locked, removing one “in the middle” will not change the positions of other sensors after reset. This option is very useful when TCW241 is used us a part of monitoring and control system managed either by SNMP or HTTP API commands.

  • Page 14: Setup Page

    Default descriptions can be changed on “Setup->Input/Output” page. 7.1.3. Data - analog inputs section Analog inputs can be used for monitoring of analog sensors with 0-60 voltage outputs. All analog inputs are not galvanic isolated. For every analog input 3 variables – “Unit”, “Multiplier” and “Offset” can be set in section “Setup- Input/Output”.

  • Page 15: Smtp Setup

    The “Hostname” is up to 15 characters. It is shown in search results of TCW discoverer. It is recommended to use public DNS server (8.8.8.8, 8.8.4.4 etc.) rather than default gateway. 7.2.2. SMTP This page is used to enter valid SMTP settings for email alerts and recipients’ addresses. 7.2.2.1.

    7.2.3. Input/Output 7.2.3.1. 1-Wire sensors For every 1-Wire sensor, a description up to 15 characters can be set. For all sensors “Offset” field is enabled. Number from this field is used for simple correction of displayed value. For some specific sensor, like TSA200, TSV200 etc., fields “Unit” and “Multiplier” are also available.

  • Page 18: Relay Outputs

    Example: For humidity sensor HIH-4000-003 following parameter (coming from datasheet) should be set for fine work: Unit - %RH Offset - 0.826 Multiplier - 31.74, the value is of slope parameter (1/0.0315); inverted If the output voltage of this sensor is 3.198V on the monitoring page will be shown 75.28% RH: 75.28 = (3.198 –...
  • Page 19 • “Virtual input z” - the relay is activated from the value from specified virtual item (cloned analog input or 1-Wire sensor) and rules for ranges specified in “Setup->Alarm conditions”; z is number from 1 to 4; • “Digital input z” - the relay follows the state of specified digital input; z is number from 1 to 2;...
  • Page 20 Example: TCW241, 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 a checkbox.
  • Page 22 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. General In this section, some general parameter for identification of device can be set. 7.2.5.2. WEB access In this section, WEB access authentication can be deactivated.
  • Page 23 12 hours. 7.3. Services 7.3.1. MODBUS TCW241 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. 7.3.3. HTTP post TCW241 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 25 7.3.4. Schedule TCW241 supports four schedules. In every schedule, up to four different tasks can be set. The schedules are useful for creating tasks that vary with calendar dates. It is possible to combine two relays in control of one device - one relay follows monitored parameter and other follows the schedule.

  • Page 26: Dynamic Dns

    The username and password can be up to 31 characters long. 7.4.2. Backup/Restore The TCW241 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 27 Attention! Don’t turn off the power supply during the update. Turning off the power supply will damage the device. 7.5. Logout The TCW241 support multisession, but the good practice is to log out after finishing the work. 8. Protocols and API 8.1. SNMP Simple Network Management Protocol (SNMP) is a standard internet protocol for managing devices on IP networks.

    8.3. MODBUS TCP/IP Modbus TCP/IPprotocol is a serial communications protocol originally published by Modicon in 1979. It is used to establish master-slave/client-server communication between intelligent devices. Modbus TCP/IP is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.
