The EasyCAT HAT allows to a Raspberry board to become an EtherCAT® Slave. The union of the world Raspberry and the world EtherCAT® will allow you to create innumerable devices for the automation in a simple, rapid and economic way. Some of the possible applications are:
- I/O devices both analogical and digital with possibility of pre-elaboration and elaboration of the signals as averages, linearizations, filters, etc …
- Generators of PWM signals to pilot motor and other
- Serial gateways RS-232, RS-485, CAN, Modbus TCP/IP, ecc …from and toward EtherCAT®
- Operator Panels
- Detection and data storage
- Emulators of other EtherCAT® devices
CharacteristicsThe EasyCAT HAT allows to exchange on the bus EtherCAT® 32 byte in input and 32 byte in output, configurable up to 128 byte. The communication is totally managed in Hardware and the exchange of data with the processor is made via SPI.
The EasyCAT Shield can support three types of synchronization: Free RUN, SM Sync and Distributed Clocks.
The EasyCAT board is shipped configured for 32+32 bytes, I.E. it is capable to exchange, out of the box, 32 bytes in input and 32 bytes in output, with an EtherCAT® master.
This is very simple, as everything is already defined and the user has nothing to do other than accessing the input/output variables in his application, but, in some situations, it may be useful to modify this fixed pattern, to better meet our needs. For instance it could be required to exchange more than 32+32 bytes, or to customize the names and the data types of the variables, in order to use them in a more comfortable way in our application.
The Easy Configurator is a software tool that allows you to do this in a simple and immediate way without having to dig into the complexity of the EtherCAT® specifications.
To meet the request of many Customers who ask for a simple software tool to test the applications made with our EasyCAT boards, we have developed the Easy Navigator. It is a very basic EtherCAT® Master with a friendly and intuitive HMI where You can easily read and write values from/to the EasyCAT boards. It's not required any special library as WinPCAP because it uses the feature of the EtherCAT® protocol to be encapsulated in an UDP frame. Then simply connect Your EasyCAT board to the LAN port of Your PC, run the tool and enjoy the EtherCAT®.

Open Source Master with which to test our cardsThere are numerous EtherCAT® Masters on the market, some of which are Open Source and are a valid help to start testing with our cards. The ones we recommend are three:
EtherCAT Explorer that works on Windows
IgH EtherCAT Master that works on Linux
SOEM that works on Windows and Linux.
