  • Page 2: Web Server - Ws10

    DATA LOGGING The WS10 can be configures to periodically log the values of a group of registers on its Flash memory. This historical logging can be sent out by e- mail or directly to a computer. This function allows the WS10 to act as a Data Logger for the variables read from the equipments in the Modbus network or from its built-in signal inputs.
  • Page 3 PERIODICAL DATA TRANSMISSION The data acquired by the WS10 can be sent periodically to any accessible computer in the Ethernet or Internet (using a conventional or mobile Modem), being received by a TCP server application and stored in a place and format defined by the user. Both instantaneous and historical register values can be sent to the remote server.

  • Page 4: Electrical Connections

    ELECTRICAL CONNECTIONS POWER SUPPLY Terminals 17 and 18 are the power supply inputs of the WS10, accepting any voltage input between 100 and 240 Vac. A few seconds after power- on the STATUS indicator blinks, indicating the WS10 is running.
  • Page 5 ISO485-2, in the RTS mode, can be used. The DTR signal is kept fixed in +5V and used to power the RS232 side of the converter. The CTS signal is also kept fixed in +5 V to enable the WS10 for transmitting. The RJ12 to DB9 or DB25 cable adaptor is described in the table below. It is necessary to wire all the signals as shown.

  • Page 6: Ws10 Configuration

    Telnet client applications can be used. In order to configure the WS10, it must be powered and connected to the Ethernet though a hub or switch, or directly to the Ethernet interface of a computer (in this case a cross cable must be used). The WS10 IP address must be known to get FTP or Telnet access to the WS10.
  • Page 7 DHCP Server, typically a few weeks. If the WS10 is kept away from the network beyond the IP expiration date, then it will probably get a new IP address when it returns to operation. To avoid this possibility of having a new IP address assigned to the WS10, the DHCP Server can be configured to keep a permanent IP address for the WS10, based on its MAC address.
  • Page 8 Addresses for DNS servers. CHIP.INI FILE The CHIP.INI file belongs to the WS10 operating system and shall not be altered, except in particular situations, listed below. Tampering on this file may result on WS10 failure. Only in the cases listed below should the CHIP.INI file be modified: •...

  • Page 9: Local Inputs And Outputs Configurations

    DecimalSeparator=. WS10. In the example, one input is defined as analog, and the decimal separator is a dot. [Input1] All parameters for each of the 4 inputs are defined on sections [Input1], [Input2], [Input3] and Tag=LIN1 [Input4].

  • Page 11 Calibration is configured in 2 parameters for each channel on the LOCALIO.CFG file: CalLow and CalHigh. During calibration the values of these parameters need to be changed using the described FTP procedures. Remember to reboot the WS10 after the transfer of a new configuration file.

  • Page 12: Modbus Rtu Network Configuration - Ws10 As Master

    MODBUS RTU NETWORK CONFIGURATION – WS10 AS MASTER The WS10 can be configured as a Modbus master, and can read or write on memory locations of other Modbus devices on the same network. If the MODBUS.CFG file exists on the WS10, this function is enabled and the WS10 starts scanning the network according to the configuration of devices and registers.
  • Page 13 The error counter (.ErrCnt) is a read-write value that contains the accumulated number of communication errors detected for the associated register or block register. The error and error counter values are not updated on write operations to the Modbus network. The WS10 doesn’t offer any function to validate the success of a write operation into a Modbus slave.

  • Page 14: Alarms Supervision Configuration

    The WS10 can compare the value of any register against limits defined as constants or other registers. The result of the comparison is assigned to a new alarm register. Based on the result of the alarm, registers can be written to, allowing the WS10 to take actions based on the detected alarm condition.

  • Page 15: Data Logger Configuration

    DATA LOGGER CONFIGURATION The WS10 can be programmed to periodically save a set of register values and time stamps on its flash memory as a file. This file can be transferred to the PC using FTP or can be automatically sent as an email attachment.
  • Page 16 To integrate the data logger to the email and periodical data transmission functions of the WS10, two tags are defined on the _INTERNAL_ device of the WS10 to identify the data logger content. If one of these tags is included on the list of tags for delivering, the content of the log file will be attached to the email message or sent to the specified server.

  • Page 17: Html Page Server Configuration

    The default page of the WS10 is named MAIN.HTM. If a page with this name is stored in the WS10, it will be exhibited on the browser when only the WS10 IP address is typed at the address line. All web server files must be located at the WEB folder or in its subfolders.
  • Page 18 </html> The example page 2 uses Java Script to format date and time information from the WS10 real time clock, and to execute mathematical operations before presenting the data. This is an important feature, since sometimes the data measured or acquired by the WS10 is not in the desired engineering unit for exhibition.
  • Page 19 The tag name must remain untouched to inform to the WS10 CGI script the name of the destination register for the written data. The second usage of the same tag is enclosed by the percent characters to allow the WS10 to replace the tag name with the corresponding value, which will be used as the initial value for the form field.

  • Page 20: Periodical Data Transmission Configuration

    PERIODICAL DATA TRANSMISSION CONFIGURATION The WS10 can be configured to periodically send data to a host computer. This host computer must run a dedicated application that accepts a socket connection requested by the WS10 and receive and store the sent data on files or database. The periodical data transmission function of the WS10 is enabled by the inclusion of the CLITCP.CFG file at the WS10.
  • Page 21 0 to it after the message is sent. Novus offers at no cost a Windows application to run at the host computer to accept connection and data from multiple WS10. Received data is saved on text files, one for each WS10. Source code in C language is included.

  • Page 22: E-Mail Configuration

    Ethernet or PPP (modem) interface. The Ethernet is used when the SMTP server is located on the network or at the internet accessed through the gateway. PPP connection is used when the WS10 in installed on remote locations where the network is not available. The WS10 can dial to a internet server provider and use its SMTP server to route the e-mail messages.
  • Page 23 Depending on the type of connection to the SMTP server, a long time should be required to transfer the message. This is more critical with PPP (modem) connection, where connection negotiation may take one minute or more. The message is constructed by the WS10 after the connection to the SMTP server is established, and all dynamic information will be acquired at this moment.

  • Page 24: Modbus Rtu Network Configuration - Ws10 As Slave

    MODBUS RTU NETWORK CONFIGURATION – WS10 AS SLAVE The WS10 can be configured to act as a Modbus RTU slave on a serial port. When the WS10 is a Modbus RTU master on one serial port and slave on the other serial port, it can be used as a Modbus RTU concentrator.

  • Page 25: Modbus Tcp Network Configuration - Ws10 As Server Or Gateway

    WS10.In this case, WS10 is acting as a server. If the message received from the client is for a unit other than 255, WS10 will forward that message to the ModbusRTU sub-network. If in this sub- network exists a ModbusRTU slave whose address matches the specified unit, the message will be interpreted, executed and answered by this slave.
  • Page 26 All Modbus registers defined in this map can contain values up to 16 bits long. To address an WS10 register containing a 32 bits value, it is necessary to create 2 Modbus registers, one associated to the upper 16 bits and the other to the lower 16 bits of the WS10 register, as in the following example: _INTERNAL_/IN1CNT.Hi = 5...

  • Page 27: Configuring The Modem To Start A Data Call - Ppp Client

    CONFIGURING THE MODEM TO START A DATA CALL – PPP CLIENT When a modem is connected to one of the serial ports (usually the serial port 2), the WS10 can be configured to start a data call using PPP (Point to Point Protocol).
  • Page 28 IdleTimeout 0 to 65535 the WS10. If the value 0 is defined, the connection will not be aborted due to inactivity. It is strongly recommended to set a non-zero value. Usual setting is 60 seconds. Time in minutes between connection retry after a connection error. Don’t set a low value 0 to 65535 for this parameter if the WS10 is configured to receive data calls.

    = 0, 1 or 2). If the internal modem of the WS10 answers a data call but the calling computer reports that a connections could not be established, try to replace at CHIP.INI file the line , and reboot the WS10.

  • Page 30: Dns Configuration

    WS10 needs access to a DNS Server. If WS10 is using dynamic IP (DHCP enabled), possibly a DNS address has been assigned by the DHCP server. If WS10 is using a fixed IP or if the assigned DNS address is invalid, a DNS configuration can be established for the WS10 by including a file DNS.CFG, similar to the following example.

  • Page 31: Secutity Issues On The Ws10

    FTP ACCESS Up to 2 authorized FTP users can be configured on the WS10. With factory settings, the WS10 has one configured FTP user (ftp/ftp). Since the second user is not configured, the anonymous ftp user is enabled. It is not recommended to disable the FTP server, since it is the only path to access and change the configuration files.
