Watlow Electric Mfg. Co.
The EM Gateway delivers an immediate solution for adapting Watlow standard controllers to Ethernet networks, allowing users to monitor and control processes remotely through PCs with Ethernet connections. It provides a cost-effective alternative to purchasing new controllers capable of communicating data within an existing system. The EM Gateway communicates with Watlow controllers via a Modbus(tm) EIA 485/EIA 232 communications network, and provides an operator interface by serving web pages to the host Internet browser. The unit supports up to 16 controllers in any combination, making it ideal for applications that require multiple loops of control.
