Project: October 2002 – November 2002 (2 months)

Description

Development of an application program for Soft PLC in C. The machine simultaneously sews two sides of a mop. It consists of a pneumatic gripping device, a feed drive and a puller drive; two servo drives each driving an industrial sewing machine, a thread chopper and a thread extractor. The drives are controlled by the PLC via the CAN bus (CANopen protocol) and the remaining actuators and sensors via digital inputs / outputs. The sewing machine is operated via a display that communicates with the PLC via the CAN bus.

  • Easy to use access to 8-bit, 16-bit und 32-bit objects (CiA encoding rules)
  • Adjustable time-out monitoring (on time-out an SDO abort message will be sent)
  • Detailed error feedback (communication errors or SDO abort codes)
• NMT-Broadcast (Network Management according to CiA DS-301, version 4.0)
• LSS Services (Layer Settings Services according to CiA DSP-305, version 1.0)
• LMT Services (Layer Management Services according to CiA DS-205, part 1 & 2)
• Event Queue for event-driven message processing, e.g. for:
  • Receive-PDOs (RxPDOs)
  • Emergency-Messages
  • Heartbeat-Messages
• Access to CAN Layer 2:
  • Transmit Message (e.g. for TxPDOs, SYNC-Object, TIME-Object)
  • Request Message (e.g. for RTR-PDOs, Node-Guarding)

The package is characterized by low usage of microcontroller resources. The software library is also available for Infineon XC16x (TwinCan) and Mitsubishi M16C (Renesas) microcontrollers.
Support of other microcontrollers on request.

Project: April 2001 – June 2002 (15 months)

Description

Key responsible for the design and development of a family of motion controllers within low power range (50 to 400 watts). The decentralized intelligent motion control system with integrated motor amplifier and CANopen interface can be used as an integrated or external control for motors with or without brushes. Developed for positioning and speed control, the motion controller offers various positioning modes, as well as homing modes and manual modes. Operation takes place via CANopen device profile CiA DSP-402 or via programmable digital inputs/outputs. In addition to the development activities, customer support and on-site commissioning were also part of my task spectrum.

Description

Collaboration in the planning and creating of an electronic control system for a compact drive with EC motor technology in the power range up to 100 watts. Power and positioning electronics as well as a spur gear with needle bearing are attached to the motor. Only one supply cable and one fieldbus cable are required for the control. Communication takes place via the CAN bus according to the CANopen device profile CiA DSP-402 (Device Profile for Drives and Motion Control).

Project: May 1996 – December 1997 (20 months)

Description

Collaboration in the development of an electronic control system for a linear drive with an adjustable motor. The drive is used for linear movements in machines / systems and is especially suitable for industrial applications with heavy loads (up to 20 KN). A sturdy aluminum housing integrates motor, gearbox and control electronics. Operation with all options (speed, positioning, soft start / stop, time-dependent functions etc.) can be programmed directly at the drive itself or through a system interface (for example CAN / CANopen, Interbus, Profibus).

Description

Collaboration in the development of an electronic control system for the operation of fans (EC technology) used in clean room areas and building air conditioning. Fan controllers are connected via RS-485 bus with a hierarchical, multi-stage topology. At most, 31 x 8 x 31 devices can be networked; the largest installation included around 2,500 fan units (chip fabrication). Operation and visualization, installation and maintenance were conducted via a RS-232/RS-485 gateway on an industrial PC. The cycle time on the PC takes around 5 minutes with 7,688 fan units.
