pc based solutions

Overview:

• IPC-Control based on Windows CE.NET
• PC without fan and harddisk
• Beckhoff TwinCAT control softwrae with hard realtime (15μs jitter, time base 1ms)
• PLC software, technology software and visualisation on one PC
• Remote diagnostics via network or modem
• TFT operator panel with touchscreen
• Data saving by flash memory (compactflash, USB-stick) or network

Conception of the control:

• PanelPC
• EtherCAT fieldbus
• Distance for I/O up to 100m (between 2 stations)
• USB- and RS232 interface
• Optional additional fieldbus (Profibus, CAN, Sercos, ...)

 Operator panel:

• Panel PC - Industrial-PC intergated in the panel
• 12'' TFT display
• Touchscreen
• 12 function keys for screen selection
• Numerical keyboard, cursor block
• 10 PLC-keys with LED for activation of special functions
• EtherCAT fieldbus 100MBit
• Ethernet 100/1000 MBit
• Installation in the wall of the switch board or panel version

Advantage at a glance:

• Control system for combine PLC-, motion control- and visualisation functions
• Function independent hardware, all software modules are installed in one CPU
• Industrial PC with PLC chracteristics, without fan and rotating memory disk, fast booting, real time clock, exchange of programs by storage cards, remanent memory and operation without UPS
• Efficient CPU; Intel Celeron M, 1 GHZ Taktfrequenz
• Operation system of the latest generation: Microsoft Windows CE.NET
• Ethernet, EtherCAT, COM1 and USB already installed in the basic version
• Support of the most fieldbus systems like Profibus, CANOpen, DeveiceNET, SERCOS and Lightbus
• Ability to fit for WEB-server or FTP-server for internet-/intranet applications
• Via analog modem conected to the serial interface PLC software changes and Remote Desctop (screen 1 to 1 from the remote computer visible) can be done.
• Low heat and low power consumption
• Small measurements of the system require little space within the switch board or terminal box

Function overview:

• Temperature control for extruder and head, 2-and 3 point controller, self optimizing
• Wall thickness control up to 10 channels (selectively 100, 200 or 400 setpoints)
• Accumulator head operation (constant or profiled, 3 heads)
• Extruder speed control, synchronized adjustment when operation more than 1 extruder
• Parison lenght control in case of continuous extrusion
• Filling level control and die adjustment during accumulator head operation
• Distance cams for clamping unit and blowpin
• Closed loop motion control for hydraulic axis
  • Blow mould open / close
  • Blowpin movement
  • Blow mould movement
  • Scope functions
• Motion control for electrical axis
• Display of melt temperature, melt pressure, extruder speed, extruder torque or current
• Monitoring of process parameters as e.g. melt temperature, melt pressure, Timers, ect.
• Sequence control of the machine - presections, timers and counters are shown on the display
• Display of blowing devolution in a diagram
• Diagnostics, error messages in plain text with timestamp
• Operator protocal: Each change of value by the user is logged in a file (wtih following information: timestamp, user, user-level, old value, new value).
• Process data monitoring: important process data (e.g. cycle time, blowing time, extruder rpm, melt pressure, melt temperature, other temperatures, etc.) are displayed in a chart and logged in a file (text-, XML-File or connection to SQL-server) for each cycle.
• Integrated scope functionality of motion actual- and setpoint- values
• Configurable access levels: The access of each input control (input fileds, preselections. timers. check boxes, buttons, ...) can be changed individual on screen.
• Limit values for numeric input can be changed individual on screen.
• Saving of setting parameters internal, on USB-stick or network. The setting paramaters can be organized in different groups like wallthickness-, temperture or movement values.
• Language reversal for up t 8 languages at the same time. (asia character sets are supported)
• Access control via PIN-code, optional fingerprint. 3 access level, 1 administrator
• Hardcopy function: One or all screen pages can be stored on USB-stick or network.
• Online help: At each page the help button displays the help page for this screen in the browser.
• The complete user manual is deposited in HTML-files on the system.
