Web Server – WS10
NOVUS AUTOMATION 3/33
ALARM SUPERVISION
In this application, the WS10 continuously compares the content of its registers against user programmed limits. The result of this comparison is
assigned to a new register that can be used to trigger a local output, write in a remote equipment through the Modbus RTU, send an e-mail or send
information to a remote server.
TRANSMISSION OF E-MAIL OR MOBILE PHONE MESSAGES
The WS10 can be configured to send e-mails automatically to an address list. The transmission can be periodical or by exception, based on
register values. The e-mails are sent through the Ethernet or Modem and have a dynamic content, sending process data to the recipient. The
message sending to cell phones can be done by email (depending on the routing service offered by the mobile phone operator) or directly to a
GSM modem connected to the WS10. The e-mail may include, as an attached file, the historical data stored in its memory.
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.
APPLICATION TOPOLOGY
LOCAL OPERATION
Connected to a local network, WS10 can bridge a ModbusRTU network to existing SCADA using Ethernet, expanding data accessibility to virtually
all networked computers using internet browser. WS10 can also log historical data, monitor alarm conditions and send e-mail messages in
periodical or exception basis. WS10 is an alternative to SCADA in small applications. When the network connection to the internet is properly
configured, WS10 data can be accessed from external locations, both by SCADA systems and browsers. The following figure shows WS10 in local
application.
REMOTE OPERATION
Installed on a remote site, WS10 can connect trough a modem to a fixed (optional internal modem) or cellular phone line. Using this connection,
WS10 can access internet and send e-mail messages on abnormal conditions or periodically. WS10 can also transfer historical data to a networked
computer. Its ability to answer data calls allows dial-up access using SCADA or browser. Remotely installed, WS10 allows additions functionalities
when compared to conventional remote units that can only transfer data periodically. The following figure shows WS10 in a remote application.
CONFIGURATION
The WS10 configuration is accomplished with usual Internet tools available in most computers: Telnet and FTP (File Transfer Protocol). Telnet is
used for IP address configuration, and FTP it is used for transferring the configuration files to the WS10.
The various functions of the WS10 are enabled by the presence of the correspondent configuration files, containing the parameters required for
configuring an application.
