| WebControl™ Universal Industrial Controller |
 |
+ Introduction
Connecting and controlling industrial and office equipment by application servers or web browsers can be
costly and challenging. WebControl™ is an innovative, flexible, and affordable solutions that
extend computer servers′ capabilities. It is a device allowing integrating with
network gateway and router to form our patent pending smart grid technology that we have been working
since 2007.
Harnessing the power and openness of Internet web technology, WebControl™ uses W3C standard-based
client/server communication methods to bring remote monitoring and control of equipment to any web
browser -- anywhere, anytime, and with unsurpassed convenience and flexibility -- or to a web server,
which can use GET/WGET to read status of input and output of other equipment through WebControl™
thus automate monitoring and control through web-based applications.
WebControl offers a powerful set of capabilities including simultaneous monitoring of digital and analog
sensor signals, temperature, and humidity sensors, and TTL output status through its programmable Boolean Run Engine.
Simply connect WebControl to an appropriate power source, the LAN, and the desired equipment,
and remote monitoring and control is just a mouse-click away.
+ Variety Inputs Support
WebControl™ can simultanously connect to 8 digital inputs, 3x10 bits A/D analog inputs provides 1024 steps accuracy, 8 optional
DS1820/DS1822 based digital temperature sensors, and 1 optional Honeywell HIH-4000 Series humidity sensor.
WebControl also has 20 built-in timers based on NTP or on board crystal to maintain accurate time events.
All these inputs can be used to feed to the Boolean Run Engine for decision making. Those information also
can be rendered to clients on the remote sites through browser and can also be made available to server-based
applications running on a web server.
+ Flexible Output
The eight TTL output is by default at logic zero. When an output is triggered or turned on, it
sends out 5V, maximum drive current 20MA per output. It is capable to drive an optical isolated SSR (Solid State Relay, normal
input control voltage 3-32V current is < 10mA) device to run a motor, siren, light, heater, refrigerator,
or other desired component.
WebControl™ allows user to control each output through browser from thousands miles away, or though
its built-in BRE(Boolean Run Engine)automatically, or through the WGET protocol from application servers.
+ Sophiscated Control
WebControl™′s BRE(Boolean Run Engine) allows AND, OR, delay, or momentary on for each output based
on all the I/O condition. There is no learning curve, simply use browser and keyboard to enter the I/O needed
for the control logic. It has delay function allow 0 to 6335 seconds delay for ON or OFF in the BRE. The
momentary ON function has resolution of 0.1 to 100 second(s).
WebControl™ PLC has a true PLC firmware. The PLC firmware allows user to write assembly like PLC code to compare inputs,
define timer or delays, determine when to send email notifications. Users can write up to 1000 lines of PLC code. Through PLC logic
user can decide using email or WEBSET function to notify user on the web site or email, or text message. There are
real examples in the PLC User Guide for reference. PLC firmware is very flexible and powerful.
+ Simple to Install and Manage
WebControl resides as a well-behaved 10BaseT-interfaced device on the local network, and has a
built-in DHCP client to automate network configuration that can be defeated to assign a fixed IP address via
WebControl′s browser-based interface. WebControl′s host name can be set as desired for
installations with multiple WebControl units, and local time zone to reflect the location.
WebControl has an embedded web server to facilitate its browser-based interface, and built-in SMTP,
and NTP time servers facilitate outbound email notifications, and time synchronization.
WebControl provides authenticated access, and security can be enhanced by allowing network access to
WebControl from only authorized IP address ranges.
+ Automatic Notifications
WebControl is capable of automatically sending email notifications to a specified user, a mailing list, or a
cell phone when the state changes on any of its eight outputs. With this notification feature, advice can be
sent automatically, for example, when the temperature exceeds 90 degrees and the air conditioner is turned off,
when humidity has reached 90% and a humidifier is turned on, or when a secure area has been breached and a siren is activated.
WebControl firmware now also support setting value on another Webcontrol board, or send to the server CGI code.
+ Energy Efficient Device
WebControl™ requires 6-40V DC power source absolutely not exceed 40VDC power source. Its current related to the supply voltage, mostly not
consumes more than 170MA. (< 2 watts. When driving power load, the load driven current is in addition to the WebControl CPU.)
