Praxis Automation Technology has used CPDev as a core of our range of PLC products for the last 15
years. CPDev has been the runtime of all our control logic in PLC products over the last 15 years
controlling key operations, maintaining safety on board and increasing the operational efficiency of
roughly 5000 sea going vessels world wide. Some notable systems in which CPDev was used (but not
limited to):

1. Power management system: controlling and synchronizing generators to the vessels grid,
maintaining a redundant power system for the vessel with a spinning reserve.
2. Fire Alarm System: monitoring large arrays of fire detection sensors and manual call points
and escalating alarms to notify the crew.
3. Bridge panels: navigation light control, wiper control, watch alarm system
4. Electric propulsion: Battery Management System, Energy Management System, High power
inverter.
5. Ballast control system
6. Chemical/nuclear warfare lockdown system on frigates for several navies.
7. Heading Control System (autopilot)
New developments used by Praxis (last 3 years):

1. SoftPLC development with Wincontroller on Windows devices.
a. Used as energy management system for 3rd party battery systems
b. Automatic heading controller
c. Linux based new generation of PLC’s
2. More advanced debugging features like step through debugging necessary for developing
more complex control logic and larger systems
3. Libraries for maintaining standardized logic blocks making our engineering process more
efficient.

Some notable facts:
1. In the last 15 years roughly 5000 ships have been equipped with PLC’s that use CPDev for it;s
runtime logic
2. That amounts to 30000-40000 PLC devices delivered with CPDev.
3. Lately CPDev has been a key factor in our environmentally friendly full electric/hybrid electric
projects which is fundamental to the marine industries 2040 goal of being carbon neutral.
