Ordering Information 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. USB Plug & Play • USB Plug and Play: For local monitoring and reconfiguration of your WebMasterONE via LapTop or dedicated on-site PC. • ShoulderTap® Internet Communications: For monitoring and reconfiguration of your WebMasterONE remotely via the Internet (requires landline modem card option). ISP Walchem Web Page Modem • DirectTap Modem-to-Modem: For remote monitoring and reconfiguration of your WebMasterONE using traditional modem- to-modem communications (requires landline modem card option). • Ethernet: For monitoring and reconfiguration of your WebMasterONE via Local Area Network or remotely via the Internet Phone Company • Cellular: For monitoring and reconfiguration of your WebMasterONE Cell Service provider remotely via the Internet (requires cell modem and VTouch option). ETHERNET NETWORKING 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.
