require some or all of the following approaches. Wired connections are often simple, visible and easy to install. However, they have minimal flexibility as a new feature requires new wiring. Serial communication bus systems are used extensively, because of the need for reliable, real- time operations and work-in-process feedback. Varying market segment


A well-designed HMI


system should not simply present control functions and information, but rather offer users active


functions to perform and also provide tangible feedback and system information.


connectivity requirements have resulted in numerous unique bus standards being defined and deployed. Some systems offer faster reaction times, whereas others may allow for more devices to be connect- ed or larger amounts of data to be transferred. Examples include: field bus pro-


tocols for interconnecting industrial drives, motors, actuators, and con- trollers, such as PROFIBUS, Device - Net and ControlNet; Ether CAT industrial Ethernet protocol, which is used in a wide variety of semicon- ductor and flat panel display manu- facturing operations; and the SECS/GEM standard, which allows manufacturers to provide a common machine interface for all factory or fabrication facility use. Wireless technologies, such as


Wi-Fi, Bluetooth, ZigBee, and NFC, allow real-time data transmission, application mobility and remote management capabilities on a local, national, or even international level by using mobile communication net- works, such as cellular, GPRS, 4G, and WiMax. In electronic production


Kurz Offers New Semi Transparent Special Effect Labeling


Fürth, Germany — Kurz has intro- duced a new Lumafin grade for narrow web printing. The special light and color effects of this transfer product are now available for roll-fed labels. Lumafin is available in grades


for hot stamping, cold transfer and digital transfer. The product can be used like a dry varnish as a large- area or spot coating. It produces a semi-transparent color transfer and allows the printed motifs underneath to shine through in a deeper or mod- ified color. It overlays the print image like a glossy veil and makes it appear as if at a depth. As the view- ing angle is changed an eye-catching effect occurs Contact: Leonhard Kurz

applications, these popular wireless communication are also typically based on IEEE 802 standards. HMI systems are the principal


point of contact between the user and a machine or process, and their effec- tiveness can potentially impact the success or failure of a system. A well- designed HMI system should not simply present control functions and information, but rather offer users active functions to perform and also provide tangible feedback and sys- tem information. A poorly designed HMI system


can alienate users or potential cus- tomers or encourage them to circum- navigate the system, resulting in poor or unsafe system performance.


IP-rated controls ensure reliable operation in harsh environments.


HMIs should create an optimal user experience with a sophisticated mix of design and layout considerations, such as contemporary style, color,


and tactile response, coupled with ergonomic and intuitive operation. In electronics production appli-


cations, a well-designed HMI system that meets user requirements, indus- try standards, and government regu- lations is a key component in the overall sound design of the equip- ment itself. By working directly with a knowledgeable HMI expert, design- ers can integrate an HMI system that successfully satisfies the unique demands of the electronics produc- tion environment.
