SPS IPC Drives: HMI and controller news

Several exhibitors at the SPS/IPC/Drives automation trade fair in Nuremberg presented its recently developed products with HMI and control functionality. The CAN-capable part of such devices mostly supports the CANopen higher-layer protocol.

CAN IS A VERY ESTABLISHED INTERFACE in the automotive and industrial HMI and controller applications. End of the nineties, some HMI manufacturers tried to specify a CANopen device profile for human-machine interfaces. But, because of large diversity of functions, which may be offered by such units, the companies could not find a uniform solution. As no standardized CANopen profile for HMIs is existing, the devices mostly support the CANopen NMT (network management) slave functionality as specified in the general CANopen application layer and communication profile CiA 301.
The industrial controllers often support the CANopen NMT master functionality, which is defined in the additional CiA 302 specification. Unfortunately, not all of them are CANopen-compliant, because an NMT master shall include the NMT slave functionality, but several of the controllers are only able to control the NMT slaves without being NMT slaves himself.


Drive.Web Automation (USA) is currently working on the CAN-connectable version of the Smarty programmable controller series. The devices provides the functions of networking, process control, programmable logic control, remote I/Os and interfaces to third party drives, operator stations, PLCs and Scada systems. Smarty Specials are pre-configured units for applications such as open loop and closed loop winders, master/slave drive sections and customized functions.

E.E.P.D. (Germany) introduced the CAN-connectable Profive G95 single board computer (SBC) for digital signage, monitor and network applications in stationary and mobile devices. The PC offers three display interfaces, an LVDS port, three Gigabit Ethernet ports, two CAN, USB, Sata, PCIe, SD Mini Card, EIA-485 and EIA-232 interfaces. The UEFI operating system for 64-bit Windows or Linux is shipped with the device.

Elrest Automationssysteme (Germany) presented the Combo Control CM module including the IEC-61131-3-programmable PLC, the Eladesign HMI function and a web/ftp server. The device offers two CANopen, EIA-485, EIA-232 and Ethernet interfaces. The distributed CM system consists of modules for stepper motor control, drives, digital and analog I/Os as well as for memory extension. For visualization company's CAN-enabled Visio or Visio Control HMI series with Estudio software may be used.

Frenzel + Berg Electronic (Germany) launched the 3,3-V Hipecs Core10 embedded PLC module with two CANopen ports supporting NMT slave and NMT master functionality. It is a successor of the proven CANopen-capable Easy series. Introduced were the Ethernet interface with a web server and TCP/IP support, a USB interface and an SD card reader. The SGI interface allows Codesys target visualization on company's HMIs. Codesys libraries for stepper motor control, encoder handling, interrupt processing, PWM, etc. are offered. The PLC module is embedded in the PLC1010, PLC1020 and PLC1030 of the Hipecs controller series.

Grossenbacher Systeme (Switzerland) shown SmartPanels SP-245 HMIs with optional Codesys soft PLC. The CANopen-connectable devices offer 3,5-inch to 7-inch TFT touch-screen displays with LED backlight and are based on a 450-MHz ARM CPU. Ethernet, USB and micro SD card ports are available. The panels support Windows CE or Linux operating systems as well as Targetvisu and Webvisu software integrated in the Codesys packet.

Inter Control (Germany) extended the CANopen-enabled Digsy display family by a 12,1-inch MTC-Terminal version. Displays with 8,4-inch and 10,4-inch were already available. The scratch resistant, non-reflecting glass-surface touch-screens accord with the requirements of crane and construction machinery manufacturers, operable with gloves. In the outrigger operation of a mobile crane, the soft keys to ascend and lower the jacks are arranged in a way that a direct reference to the particular function is available. The soft keys may also be operated by an external rotary knob with integrated keys located in the armrest of the vehicle.

LSIS Automation (Korea) introduced the XBG E and SU type controller series expansible by a CANopen communication module. The E type devices offer up to 38 I/O points whereas 284 I/Os are maximal supported by the SU type. The two available CANopen modules provide NMT slave or NMT master functionality. Bit-rates from 10 kbit/s to 1 Mbit/s, up to 64 TPDOs and up to 64 RPDOs are supported. PDO trigger modes include acyclic, cyclic, time- and event-based variants.

Moba Mobile Automation (Germany) offered CAN-based mobile controllers, HMIs and sensors. The mobile controllers with half-shell design allow combination of different controllers (different memories, I/O types and numbers) are suited for use under harsh environmental conditions. All controllers may be programmed with Codesys. The HMI MC modular concept allows to assemble up to six keyboard, joystick and display modules. As an example, the HMI MC unit combined of three modules is used on aerial work platforms.

Serad Motion Control (France) presented CAN-connectable Dialog 80 (28 keys) and Dialog 640 (33 keys) keyboard operator terminals with 74-mm x 23-mm and 122-mm x 66-mm LCD displays. The IP65-protected devices incorporate a 16-bit processor, a 512-KiB Flash, 128 KiB of non-volatile RAM and an EIA-232 port. Optional EIA-422 and EIA-485 ports are available. Company's Supervisor 80 and 240 terminals with the same LCD display sizes as for the Dialog series may be connected with PLCs, CNCs, drives and remote I/Os via CANopen.
