pc based solutions

Overview:

• IPC-Control based on Windows CE.NET
• Beckhoff TwinCAT control software with hard real time (15μs jitter, time base 1ms)
• Control software, technology software and visualisation on one PC
• Remote diagnostics via lan or modem
• 12'' TFT operator panel with touch screen
• Data saving by flash memory (compact flash, USB-stick)
• Reversal of language

System Structure:

• Installation in the wall of the switch board
• PC without fan and hard disk
• Power supply 24V DC
• analog inputs 16Bit (+/- 10V)
• analog outputs 12Bit (+/-10V)
• digitale inputs
• digitale outputs
• Amplifier for the valve (15mA, 20mA, 33mA oder 60mA)

Operator panel:

• 12'' TFT display
• Resolution 800 x 600 pixel
• Touch screen
• 12 function keys for screen selection
• Numerical keyboard, cursorblock
• 10 PLC-keys with LEDs for activation of special functions
• EtherCAT for the connection to the I/Os
• Installation in the wall of the switch board

Wall thickness profile:

• Continuous or discontinuous extrusion
• 100, 200 or 400 point wall thickness profile
• Up tp 10 channels synchron (wall thickness profile control - partial wall thickness control - multiple extrusion head)
• 1 channel parison ejection (constant or profile)
• Correction of parison elongation (linear proportion)
• Cycle time specification manually or automatically
• Parison check marks (max. 2 at the same time) simply by setting of thick or thin places
• Test position
• Control of parison length using a photo cell in case of continuous extrusion
• Filling level control of accumulator head in case of discontinuous extrusion (adjust extruder speed)
• Automatic or maunal calibration of the actual value transmitter (LVDT)
• Profile marker
• All set parameters can be stored or reloaded in an internal memory or an USB-stick
• Reversal of language for the user interface
• User access by PIN-Code

Information:

 SmartWDS is upgradeable up to complete machine control. Here the existent 12'' touch screenm the processor unit and the in- and outputs can be used. Only additional in- and outputs and a software update is required to upgrade follwing available function:

• Heating channels (up to 96 channels)
• Closed loop movement control (up to 6 axis)
• Complete machine control

Note:

Please consider by implement heating and movement control you will achieve a central data maintenance, whereby the heating- and movement-parameters are stored in the same data record.
