Tiivistelmä
This thesis was done based on the requirements provided by Wärtsilä Oyj Abp’s Automation & Controls department of the Marine Solutions sector to modify and analyse the changes for UNIC2 communication. The current system uses an internal FPGA switch which takes care of the HSR functionality. Instead of using that, an external switch will be used to minimise the COM-10 1s FPGA chips system requirements.
During the 21st, century the need for more sophisticated communication networks in motors has increased. Every vehicle on the sea, land, and air has some sort of vehicle bus communication network that interconnects components inside a vehicle. UNIC2 is Wärtsilä’s answer for a more sophisticated automation system. It uses HSR to provide high-speed communication as well as redundancy for seamless a failover against failure of any network component.
The research was conducted with the aim of investigating and analysing the current system and technologies used as well as planning, implementing, and testing of the solution. To apply the changes, the COM-10’s source code required extensive knowledge to find what needed to be changed, as well as HSR configuration to the external switch.
The result of the project was a functional UNIC2 communication system, where the modified COM-10 module is connected to an external switch via the SAN bus and the rest of the modules operate in an HSR ring topology with the switch. After disabling the internal switch on the COM-10 1 module, the resources on the FPGA chip dropped by more than 40%, giving a possibility for future FPGA application development.
