Communication

All our life is about communication

 

In practice, the controlling hardware platform inside Clotho, Lachesis and Atropos is the same. Genius control of all the Single-Use-Pump's offered by PerfuseCell. We have named this proprietary PLC hardware platform of our own design / construction for Apollon (sibling to Artemis and both children of Leto).

The Apollon unit is a super compact PLC, which houses a 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-1 and Clotho-, Lachesis or Atropos.

Clotho and Lachesis Drive Units communicated 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
