All our life is about communication

 

In practice, the controlling hardware platform inside Clotho, Lachesis and Atropos is the same. We have named this proprietary PLC hardware platform combined of parts from Kontron and of our own design / construction for Apollon.

The Apollon unit is a super compact PLC, which houses an industrial 900 MHz quad-core ARM Cortex-A7 CPU and 16 GB Ram. A range of 15-bit high speed in/out analogue and digital channels corresponding with various sensor’s and actuator’s. The ARM CPU drive a 5” TFT touch sensitive graphical display operating Linux Wheesi firmware and features also a build-in Apache webserver.

Apollon is installed inside the Hephaestus cabinet (with many other components) and hereby becomes the naked, non-intelligent Metis product. When the proprietary Clotho software is loaded into Metis – then Metis is transferred to the intelligent Clotho or Lachesis or Atropos Drive Unit for the O-SUP and A-SUP control.

Clotho, Lachesis and Atropos software is programmed in CODESYS ver 3.5 allowing:

  • any imaginable operation sequence, cycle for each diaphragm SUP (pulse ramp, pulse train, pulse length, pulse pause, stroke start, stroke length, stroke distance, cleaning pulse ramp steepness = selectable velocity)
  • real-time information about pumped volume from each diaphragm SUP
  • data acquisition into SQLite and subsequent data logging for each diaphragm SUP

The GUI, Graphical-User-Interface is principally identical between Clotho, Lachesis or Atropos.

Clotho and Lachesis Drive Units communicated via OPC-UA since:

  • 2018 with DasWare from DasGip

  • 2022 with Lucullus from SecureCell

  • 2023 with DeltaV from Emmerson

O-SUP / A-SUP installed LASER sensor communication:

Both Clio and Thalia features the Leuze LASER sensor, which online read out the actual position of the diaphragm position in real-time to the drive units PLC. The Apollon PLC in a loop with LASER and proportional valves insures the unique performance of PerfuseCell's range of products. 

Clotho / Lachesis external communication:

The integrated web-host allows the user to access the Apollon PLC via:

  • The integrated TFT touch sensitive graphical display
  • Wi-Fi / USB adapter and smartphones and pads
  • IP/TCP from many devices via Ethernet / LAN
  • OPC-UA and Modbus as standard for external software control
