Chapter One Product Overview The EM00-GATE-0000 is a gateway / bridge that allows up to 32 Watlow controllers to be directly connected to an Ethernet network. Using an HTTP Browser such as Microsoft Internet Explorer or Netscape Navigator you may access 16 controllers and view several controllers’ parameters via an onboard Web (HTTP) server. Ethernet Gateway The Ethernet gateway provides a means for monitoring and configuring runtime parameters of multiple controllers via a web browser.
Program Upgrades The gateway has a TFTP server for the purposes of reprogramming the program memory. A program update will be initiated when a TFTP client, residing on a PC, begins to write a new program file to the gateway TFTP server. When reprogramming the program memory, all other gateway services are unavailable. The gateway provides no means of updating the program memory of controller devices, such as flashing new information into the Series F4.

Chapter Three Configuration Getting Started Perform these steps; 1. Connect the EM00-GATE-0000 gateway to your computer’s Ethernet port using a cross-wired RJ45 cable or connect the EM00-GATE-0000 to a hub or network using a straight wired RJ45 Category 5 cable. The EM00-GATE-0000 is limited to a 10BaseT connection and will not work on an Ethernet port set for 100BaseT only. Use of a 10/100 hub will overcome this issue if your PC has only a 100BaseT port. 2.
You will need to configure your Gateway with your SMTP server name or address. A DNS server address must also be configured if using a SMTP name. Contact your system administrator if you don’t know the SMTP name or address. Data Logging The gateway provides no explicit means of data logging. Data can be polled via Modbus TCP by an external PC program. Consider WatView from Watlow for your setup, data logging and graphing needs.
Chapter Four HTML Pages The section describes the pages available from the EM Gateway’s Web server. When the web page is first accessed, you are prompted for a User name and Password. The default User name is ‘new’. The default Password is ‘user’. These are case sensitive. The user name and password may be changed on the security configuration page.
Use this page to disable or enable automatic page refreshing or to change the time in between refreshes. In addition, you can force a rescan of the Modbus Network. This will cause the Gateway to detect any new devices added to the serial network. Set the baud rate of the network to 9600 or 19200-baud. The value selected must match the value in all of the controllers on the serial network. Up to 16 controllers may be scanned by the Gateway using the built-in HTTP server.
Use this page to change the Gateway identification name or to change the IP Address Resolution Method. Contact your IS administrator for questions regarding these settings.
Use this page to enable notification and configure the addresses for email recipients. These recipients will receive an email when an alarm occurs on any controller. Contact your IS administrator for questions regarding these settings.
Use this page to update the time and date stored in the Gateway. This information is used to identify the time and date of alarms when emails are sent.
