The human machine interface (HMI) is where people and technology meet. Therefore, they are ubiquitous, found everywhere from vending machines to nuclear power plants.  The HMIs we’re familiar with first appeared in 1981. However, in today’s economy, with end users wary about investing in upgrades or plant expansion, HMI manufacturers have had to add features to their products that can meet a new set of needs, such as greater compliance with environmental regulations and security.

According to Claire Cerrato, director of HMI/SCADA product management, GE FANUC Intelligent Platforms, “The customer trends driving evolution in the HMI/SCADA environment are secure access to information anywhere, low cost of ownership and new regulatory and security compliance requirements. Companies are demanding the ability to manage data from the plant floor to the enterprise with solutions that can operate independently or in a fully integrated way. HMI/SCADA solutions now need to drive easy access to information from the plant floor to the remote site, whether users are in an operational center or on a mobile access device. You will see your information anytime, anywhere in a secure end-to-end system. HMI/SCADA will be the ‘advisor’ that presents that data about process, production and logistics to improve decision-making and maximize plant operations.”

End users can look for additional features in their HMIs such as HMI-PLC functionality, greater use of graphics, easier configuration tools, Internet access and extra memory from low-end HMI dedicated terminals to high-end industrial computer-based HMIs.

SiloPatrol SE Model HMI is environmentally hardened for outside installation and can monitor inventory level measurements of up to 16 sensors, one in each silo. Connection between the HMI and sensors is a single twisted-pair RS485 communications cable. The HMI provides for automatic and manual measurement updates and can convert the basic distance measurement in each silo to level, volume, weight and %-full based on user input data. Display of data is via a multi-line backlit display.
