  • Page 2: Short Description

    1. Short description TCW122B-CM is a remote IO module for monitoring and control. It has 2 digital and 2 analog inputs. The supported 1-Wire interface can handle up to 2 temperature or 2 humidity- temperature sensors. The controller has 2 relays with normally open and normally closed contacts. Every relay can be activated either remotely (WEB, SNMP etc.) or locally - from the status of monitored parameter...

  • Page 3: Led Indicators

    Endurance: 100 000 cycles (Every relay status and settings change is a memory cycle.) 4. Powering TCW122B-CM is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for use in the conditions of overvoltage category II, and priorly assessed for compliance with safety requirements.

  • Page 4: Installation

    3. Connect the I/O pins of the controller according to the required application. 4. Connect the power supply. If the red LED (STS) blinks, the main program of the controller is executed. By default TCW122B-CM comes with the following network settings: IP address: 192.168.1.2, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.1...

    The “Monitoring” page provides information about the state of the relays and digital inputs, values of analog voltages (applied on analog inputs), temperature and humidity. The state of the relay can be changed by appropriate “ON/OFF” button. To change the state of the relay for specified time “Pulse”...

    • Recipient e-mail. Username and password for WEB access to TCW122B-CM can be changed in the Web Access section. Setting the authentication to “disabled” will provide access to monitoring page without entering username and password. The HTTP port can be changed also in this section.
  • Page 8 SNMP traps are sent if: • event occurs (status change) on Digital Input 1 or Digital Input 2; measured voltage on Analog Input 1 or Analog Input 2 goes outside the range; • measured temperature goes outside the range; • •...
  • Page 9 Example: TCW122B-CM, 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 10 For digital inputs, conditional email sending can be arranged by following part of the page: Relays can be activated automatically depends on the value of the monitored parameter (humidity, temperature, analog voltage and changes on digital inputs) or manually. Only one parameter can be assigned for relay activation, at the same time: When manual activation is selected, “Pulse”...

    – the controller can send an e-mail and/or SNMP trap. 9.4. Data acquisition The TCW122B-CM can be used in Data Acquisition Systems (DAQ). The device uses SNMP v.1 protocol for communication with monitoring and management software applications. 10. 1-Wire Bus 1-Wire is a registered trademark of Maxim Integrated Products, Inc.
  • Page 13 11. Control and monitoring using SNMP TCW122B-CM can be configured and monitored through SNMP (Simple Network Management Protocol). This could be done using every SNMP 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”...

    XML is often preferred choice when it comes to M2M communication and system integration. The monitored values are transmitted in status.xml file that can be easily processed by software applications. The structure of the status.xml file is: <Monitor> <Device>TCW122B-CM</Device> <ID>5C:32:C5:AA:00:05</ID> <Hostname>TCW122B-CM</Hostname> <FW>3.10</FW> <DigitalInput1Description>Digital 1</DigitalInput1Description>...
