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. The gateway is also a bridge for Modbus messages between the Ethernet
bus and EIA-485 or EIA-232 links. The Gateway supports full product configuration; monitoring and
configuration of runtime parameters via MODBUS TCP over TCP/IP using a software package such as
Watview sold by Watlow.
Ethernet Gateway Architecture
This product has three physical connectivity points to the physical world. They are the serial (EIA-485 or
EIA-232), Ethernet port (10BaseT), and the power supply pins.
The EIA-485 / EIA-232 connection supports Modbus RTU protocol and operates as a Master port. It will
initiate data read/write requests to supported standard Watlow controllers. There exists a virtual image of
the controller’s data points in the gateway. The polling engine that initiates the Modbus RTU requests is
responsible for synchronization of the virtual image and the actual controller. Changes to control data
occur both at the controller and at the virtual image.
The 10BaseT connection supports the TCP/IP stack. At the application layer it has an HTTP (web) and
Modbus server. The HTTP server will provide current controller status from the virtual image via HTML.
The HTTP server provides a means of changing some runtime parameters via HTML. The TCP/IP stack
supports DHCP client, AutoIP, static IP, DNS client, and Netbios name resolution. The 10BaseT
connector is an RJ45 per the IEEE 802.3 specification.
The EM00-GATE-0000 can be used as a bridge for Modbus RTU messages. This is concurrent with all
other communicating functions. In this scenario, the gateway simply passes the request that comes in on
the Ethernet connection through to the EIA-485 or EIA-232 connection. When the response is returned
from the controller, it is sent back on the Ethernet connection. No processing of the packet contents is
necessary to bridge the two physical layers.

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.

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. Wire the temperature controllers to the gateway’s EIA-485 port. You may connect the gateway’s EIA232 port to a controller if you will be using only one controller, provided that the controller has an EIA232 port.
3. Wire a 24-volt AC or DC power supply to the gateway terminals. This is not polarity sensitive.
4. Configure each controller to the same baud rate (9600 or 19200) from the front panel of the
controller. Set each controller’s Modbus address to a unique number. As an example, set the first
controller to address 1, the second to address 2 and so on.
5. Power up the gateway, controllers and PC.
6. Start your Internet browser. Enter the TCP/IP address of the gateway into the browsers’ address field.
Two different addresses may be used to access the gateway. Either EMxxxxxx, where xxxxxx is the
first six digits of the serial number, or WATxxxxxx, where xxxxxx is the last six digits of the gateways’
MAC address. The MAC address is printed on a decal in the form xx:xx:xx:xx:xx:xx.
7. Select the Gateway Setup Page. Enter User name ‘new’ and Password ‘user’ by default. The
Password can be changed on the Security Configuration screen.
8. Configure the Baud Rate and range of controllers’ addresses to match those you configured in step
four.
9. Click on Rescan Modbus Network
10. Click on the back button of the browser to return to the previous page.
11. Click on the refresh button of the browser and your controllers’ information should now be visible.
Note: You must click on the refresh button within the browser to capture the latest controller information.
This information is automatically refreshed after 10 seconds by default. You may change this refresh time
using the appropriate page.
Network Services
The EM00-GATE-0000 supports DHCP client, autoIP, and static IP for address assignment. Normally you
will not need to make any changes. The user is able to configure preferences as to which services are
used if available. Intelligence is employed within the gateway to revert to backup IP assignment methods
if the primary method is unavailable.
The gateway does support DNS client and Netbios name resolution. Configuration information may be
entered at the EM Gateway Network Display Setup page.
Email Alarm Notification
The email function allows the user to send emails to four addresses alerting them of alarm conditions that
have occurred on the controllers connected to the Gateway. A button on the Graphical User Interface
(GUI) allows the user to enable or disable this feature. Emails can be generated whenever an alarm
condition occurs for each controller. An email acknowledge feature requires that the user acknowledge
the email message by operating the email acknowledge button before additional email alarm messages
can be generated for that controller. For multiloop controllers only one email acknowledge feature is
supported; if more than one loop produces an alarm, only the first alarm detected will generate an email
until acknowledged.
8
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.
Control Monitoring and Configuration
The gateway provides a means of monitoring the current process value for analog inputs of each
controller using a built-in HTTP server. It also provides a means of monitoring the present alarm status of
each controller. Additionally, you may monitor and change control set points for control loops of each
controller.
The gateway is capable of supporting Watlow Series 96 non-ramping, 97, 981, 982, 988, 989, 998, 999,
F4S, F4D, F4P, MicroDin, Power Series, CLS200and SD non-ramping controllers with up to 16
controllers in any combination.
The gateway is capable of automatically determining when a controller is connected to the serial bus. It
will identify the model and address of each controller. Controllers with duplicate Modbus addresses will
be ignored by the gateway.
You can configure the baud rate of the EIA-485 or EIA-232 bus. You may also specify which controller
addresses are scanned under the EM Gateway Setup page. The gateway supports from 1 to 16
controllers in any combination of supported model numbers. Select Rescan Modbus Network to update
the detection of controllers on the bus. The Modbus network is automatically scanned every two minutes
for new devices.

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.

This is the main page for monitoring the controllers on the Gateway. You can click on values that are located
within a box. Entering in a new value may change these values. In addition, use Alarm Ack to clear alarms when a
process value has returned within a safe operating range. Use the Email Ack to reactivate future emails for this
controller. See the controller’s user’s manuals for details of Modes, Errors, and Alarm operation.

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. Set a start address to the lowest
address number of the controller on the serial network. Set an end address to the highest address
number of the controller on the serial network.
As an example, you have your first controller set to address 23 and the last one set to 35. Set Start
Address to 23 and End Address to 35. You can limit the number of controllers accessed by the
Gateway by setting the Maximum Nodes value to less than 16.
Lastly, this page provides links to Network Setup, Email Setup, Clock Setup, Network Statistics, and
the Serial Statistics pages.

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.
12
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.

The Serial Statistic page is used to monitor the health of the controller network. These numbers will
help identify when there are issues with wiring, duplicate Modbus ID addresses or noise on
communication wires on the controller side of the network. In this example, controller number 11 is
experiencing failure in communication quality.
Timeout Errors increments anytime that a controller does not respond in an appropriate amount of
time.
Retry Errors increments anytime that a controller does not respond after 3 attempts to read
information.
CRC Errors increments anytime that the controller responds with a bad packet.
Bad Polls increments when there are timeouts and the retries did not successfully retrieve information.
Good Polls increments on each valid packet received.
Illness increments anytime that there are 5 CRC or Timeout errors in a row. After a count of 5 in the
Illness column, the controller is flagged as having no communication. On the next valid packet
received, the Illness value is cleared to zero and communications is restored.
You must refresh the browser to see these numbers update.
