PP1001-V00 - PicoServ Web Server Module

    PP1001-V00 - PicoServ Web Server Module

    Manufacturer: Compulogic

    This product is no longer available at Saelig.


    PicoServ Web Server Module

    PicoServ is a low cost, miniature web server module featuring a fully integrated Ethernet interface, a variety of interfaces to the 'real world' and EEPROM storage for web pages and other files. PicoServ provides a compact "No PC" web access solution.

    The PicoServ miniature embedded web server module is an 'Internet engine' designed to be able to provide a browser based interface over a LAN, the internet or GPRS network in a small space, at low power, at low cost and with little or no design effort.

    PicoServ supports dynamic web pages which means that real time data can be both displayed and/or updated from a standard web browser

    System designers or integrators need only be familiar with their own products or systems. The PicoServ module takes care of all the required network interfacing, network and internet communications protocols, web page and other file storage.

    Dynamic web pages are supported using an innovative and simple to use method which allows 'real world' variables and information from the host system, for example temperatures, speeds, levels, voltages, switch positions etc. to be displayed or changed using only simple HTML techniques. Virtually any number and type of host variables and parameters can be handled without any need to specify or pre-define fields on the PicoServ server.

    A simple RS232 serial interface is provided to allow data to be exchanged between the PicoServ server module and the host system. A second serial interface conforming to the I2C bus standard is also provided. In addition a number of standard intelligent interface modules are available which provide 'no development' parallel, serial, analogue, and digital I/O interfaces between the server module and the outside world.

    The relatively large file storage area of 260K bytes for an embedded web server system, which can support almost any type of file including HTML, GIF, JPEG, and JAVA, means that only standard web authoring techniques are required to be able to provide an eloquent and professional browser based interface for almost any system.

    In addition to HTTP, the Simple Network Management Protocol (SNMP) is also supported.
    SNMP is an Internet-standard protocol for managing devices on IP networks.
    Any PicoServ parameter can be read or updated using the SNMP protocol, including parameters from I/O modules and external systems. In this way the PicoServ system can be used as an "SNMP Proxy Agent" to enable the remote monitoring and control of devices not capable of supporting the SNMP protocol directly, using a network management system such as HP Open View.


    The applications areas where PicoServ could be used to provide a LAN or Internet browser based interface are probably only limited by the imagination, a few of the more obvious applications are listed below.

    Security systems
    Heating, cooling and refrigeration equipment
    IT systems monitoring
    Process monitoring & control
    Power generation plants
    Factory machinery and processes
    Vending Machines
    Municipal water & waste water treatment plants
    Medical & pathological equipment
    Environmental monitoring
    Remote on/off switching of electric motors, pumps, lighting etc.

    Dynamic Web Pages Display Real-time Data

    Expansion Modules

    As standard the PicoServ module can interface to a host system via a built-in RS232 serial or I2C bus interface, allowing static and variable data to be exchanged between the host system and the user's browser interface. This is accomplished using a very simple serial protocol which is implemented on the host system. Almost any number of data parameters can be exchanged between the host and the user in this way.

    In addition, or as an alternative to the serial interface, a number of standard interface modules are available which simply plug into the PicoServ web server module and provide a range of analogue and digital inputs and outputs. This method provides a 'no development', real world interface to the PicoServ system with the input and output variables available to the user's browser interface.

    The PicoServ expansion modules have their own processor system and have additional built-in functions such as programmable alarms, time qualification and programmable measurement offsets.

    An GSM GPRS and SMS module is also available. With this gateway, any state or variable monitored by the PicoServ system can be read or updated from a GSM mobile phone using text messaging. In addition the gateway can be configured to send an alert message based on some user defined criteria, for instance the closure of an alarm contact or a temperature threshold exceeded.

    When used with the PicoServ GSM GPRS and SMS module the GPRS version of the PicoServ Web Server module can be installed in places inaccessible to wired networks such as vehicles or vessels, creating a truly remote web based access system.

    The range of standard interface modules will be increased to include further application specific and specialist interfaces. Compulogic are also able to undertake the design and supply of PicoServ interface modules to suit individual customer requirements for specific applications.
