NHP Electrical Engineering Products has made Ethernet available on the ESA range of graphic touch screen HMI panels.

The terminals support Modbus TCP/IP and can be connected to a large variety of devices. The 10/100 Ethernet port enhances the range of ESA operator panels, from the 6” mono touch screen to the 12.1” active colour display.

These terminals support the communications options currently provided. The standard serial ports provide RS 232, RS 422, RS 485, and TTY communications interfaces while networking can also be achieved using ESANet. ESANet is a high speed network that allows both the text and graphical panels to communicate and share data with each other. Up to 32 ESA panels can be configured in a client server architecture.

Reports and alarms may be printed by connecting a printer to the parallel port. Profibus DP and CANOpen fieldbus networks are also supported. Over 150 protocols have been developed to communicate with devices like PLCs, servo drives, and temperature regulators.
