An Ethernet/Internet
Connectivity
Solution for Watlow
Modbus
™
Controllers
Watlow’s EM Gateway serves as a bridge for Modbus
™
communication between ethernet and Watlow standard
controllers. The Gateway provides a quick, convenient
and economical means of adapting controllers to ethernet
connectivity.
Ethernet communications is rapidly gaining popularity
in industrial control applications by enabling the flow of
information between processing equipment and the
company’s ethernet-based management systems.
Watlow’s EM Gateway provides an operator interface by
serving web pages to an Internet browser to support key
control operations such as process monitoring, set point
changes, alarm management and error notification. The
browser can be used to monitor the process, make set
point changes, manage alarms and generate e-mails to
notify remote locations of an alarm condition.
The gateway communicates with Watlow controllers via
a Modbus
™
EIA 485/EIA 232 communications network.

• Series 981/982
