Wolfgang Schenk (photo), Director Business Unit Electronic Control Systems, says the rugged design of the components allows it to be used in cranes and other lifting devices as well as in a multitude of other mobile applications. These include wind turbines, trains and agricultural machinery.The product family includes new controls from the iFLEX series and new iSCOUT operating consolesThe controls were developed with the new EN ISO 13849-1 standard and the new machinery directive in mind. They are available in the protection classes IP20, IP66/67 and optionally IP6k9k. They also offer an extended temperature range of between -40 and +70 degrees Celsius and are designed to fulfill high demands on shock and vibration resistance. SAFE AND SECUREMr. Schenk says the security architecture guarantees the safe operation of the control system. It consists of a security controller, a security protocol developed by Hirschmann as well as a Security Task, which monitors the main processor and the main control circuit of the application program.Through different 32 bit CPUs, the whole performance range is covered, from low-end to high-end controls. The integrated security architecture provides performance level c (SIL 1) or d (SIL 2) in accordance with EN ISO 13849-1. SYSTEM ARCHITECTUREAll Scalable Mobile Control System controls have a compact design and provide over 200 inputs and outputs that can be combined flexibly. The integrated communication interfaces include an Ethernet port (10/100 BASE-TX), a CANopen/CANopen Safety port and a USB interface. Other optional interfaces such as composite video or Zigbee ports are available, with which the controls can be optimally adapted to the requirements of the relevant application. Software modules such as function blocks for safe load indication can also be integrated. The controls have a standard software platform, so the same application can be used on all CPUs. Program or firmware updates can be implemented with a USB memory stick.The operating consoles support Ethernet and CANopen and CANopen Safety. They are available either as a monitor, as a stand-alone display or with integrated PLC.They are also available with different-sized displays (4.3 inch QVGA, 7 inch WSVGA, 10.4 inch VGA / SVGA) and with various CPUs that are adapted to the relevant number of inputs, outputs, and interfaces. They can be operated via buttons, touch screen or thumbwheel. All the consoles are designed for a temperature range of between -30 and +70 degrees Celsius. The application software of the controls and operating consoles can be programmed using CoDeSys (IEC 61131-3) or C. Hirschmann also offers a program library for control and security functions specific to individual customers' wishes as well as (on request) complete system integration, including the creation of the corresponding application programs.
