SPS IPC Drives 2014 exclusive show report

03 January, 2015

Vipa also announced 10” and 15” additions to its eco range of touch-panel HMIs. They accept two network cards, allowing them to operate on two separate networks. The fan-less panels have a resolution of 1,024 x 768 pixels and run the Windows Embedded CE 6.0 operating system.

Wago has new input modules for its fieldbus-independent I/O System 750, including an eight-channel digital input module for PTC thermistors, and four- and eight-channel analogue input modules for RTD resistance sensors.

Yaskawa has a new motion controller which, it claims, offers 50% better performance than its predecessor and cycle times as low as 125µs. the MP3300 controller (below) is based on 64-bit technology and supports both floating-point numbers and double-precision (eight byte) and 64-bit integer values. For the European market, there is a version (MP3300iec) that supports IEC 61131-3 programming, as well as PLCopen function blocks.

ELECTRICAL AND SAFETY

Balluff has extended its IO-Link Smart Light range of LED-based signal towers to include new versions with one or three segments and optional acoustic signalling. The towers (below) can be adapted to almost any requirement via a controller, without needing to set DIP switches or rely on other hardware configuration. Settings can be changed on-the-fly.

A family of IP67 non-contact reed switches from Eaton is designed to monitor safety guards, doors and flaps to PL e / SIL 3. The RS-Titan switches are supplied with actuators and come in three versions with differing mounting and cabling arrangements.

Eaton has also developed an online software tool to simplify configuring its SL4 and SL7 signal towers. Users select the required components (which can include visual and acoustic modules) and combine up to five for each tower using a drag-and-drop process. The towers can be supplied assembled to the design.

Also on the software front, Eaton has enhanced its free CurveSelect tool, making it easier to compare the tripping characteristics of protection devices. It can assess the interaction not only between Eaton products, but also those of other manufacturers.

New from Euchner is a transponder-coded safety switch that combines an electromechanical safety switch with guard locking and guard lock monitoring. A single CTP switch achieves Cat 4 / PL e without additional fault exclusion. It is also said to surpass the requirements in EN ISO 14119 for a type 4 switch with a high coding level.

Euchner was also showing a transponder-coded switch which can act as an AS-i slave via a direct ribbon-cable connection. The CES-AS-C04 switch has built-in diagnostics LEDs.

Kübler is offering a compact speed-monitoring safety module that is said to be easy to retrofit. The rail-mounting Safety-M module (below) has a signal splitter for encoder signals, reducing the need for external cabling. The module incorporates speed and position-related safety functions including SS1, S2, SOS, SLS, SDI and SSM, and, with a certified encoder, achieves SIL 3 / Pl e. An optional removable OLED display supports diagnostics and parameterising without needing a PC.

Kübler was also showing a new generation of safety modules including basic and expansion modules with SIL 3 /PL e and UL certification. The programmable basic modules carry out speed and position acquisition tasks with master functions, and are available with digital I/O or as fieldbus gateways. Configuration data can be stored on removable memory cards. The modules can process drive-related safety functions as well as signals from safety devices. There are axis expansion modules that can be connected to incremental or absolute encoders. Teach-in of speed is possible via a button.

Omron’s Sysmac NX-S safety controller, previously incorporated in its Sysmac automation platform, is now available as a standalone device that can be operated without implementing standard control. The scalable SIL 3 / PL e controller can be used for installations with a handful of I/O, to applications needing up to 256 I/O points. Up to 63 slices can be connected with the user free to choose between safe or standard
