Communications
With an embedded web server, WebMasterONE utilizes standard TCP/IP Internet communications. Remote communications can
be established with WebMasterONE via the Internet or on a direct line with modem-to-modem capability. USB Plug and Play
and Ethernet are included to allow easy on-site access for plant personnel and system operators. Multiple users can access the
controller simultaneously. A graduated password protection system allows users varied degrees of access from view only to full
system configuration. In addition, WebMasterONE delivers a range of user-friendly information reporting tools including email
notifications for datalogs, alarms and system summaries.

Walchem has made use of the Internet as a remote access communications platform for industrial control equipment a practical
reality.  While others just attempt to reduce the cost of embedded web server hardware,  Walchem has solved the problem of the high cost
and lack of availability of a permanent connection to the Internet. 
WebMasterONE makes programming your cooling tower or boiler simple and fast and WebMasterONE does not require any
proprietary software to reside on your computer. Set-up and programming are all done via a standard web browser. Easy to follow
menus and system set-up screens make programming user friendly and intuitive. Once WebMasterONE is installed, the Start-up
menu jump-starts you through the top level set-up. The Input, Output and utility menus guide you through the rest of the programming.

Walchem’s Ethernet Networking allows you to leverage the power of the WebMasterONE communications abilities. By
using the Local Area Network (LAN) or by connecting the WebMasters together via Ethernet, you can access all the controllers on the network from a single phone line. It’s simple. Each controller includes Ethernet and the Master controller requires the Ethernet Networking “Master” capability. Utilizing a Master-Slave type relationship - one controller is configured
to be the Master or window to all the other units (Slaves) on the network.
By utilizing the existing LAN, wiring can be minimized. The controller simply plugs into the nearest LAN connection via a
standard Ethernet cable. The Master controller detects the other Walchem devices on the network and provides a single
point of access.
Modbus TCP/IP (Ethernet) is available to seamlessly connect to building energy management, distributed control, process
management and SCADA systems.

ONE simple and flexible controller for ALL your water treatment needs!
Walchem’s WebMasterONE integrates advanced sensing,
instrumentation, fluid handling, and data communications
technologies to bring you the most sophisticated cooling
tower & boiler controller in the water treatment industry.
The simple, intuitive programming makes it easy to configure
your WebMasterONE to control multiple cooling towers,
boilers, closed loops, or virtually any water treatment process.
It will monitor and control based on a wide range of direct
sensor inputs as well as measurement inputs from other devices such as corrosion, level, temperature and
pressure.
