ETHERCAT COMMUNICATION

3.1

CAN application protocol over EtherCAT

STDF EC is an EtherCAT communication embedded type of controller to support CAN
application protocol over EtherCAT (CoE). EtherCAT slave structure is as below.

Figure 3-1: EtherCAT Structure.

3.1.1 Object dictionary

Object dictionary is a dictionary of objects of the product.

3.1.2 Mailbox communication

Master and Slave commands receive service data object (SDO) at mailbox communication
(SDO communication). This communication method is the way of message transfer and the
master delivers commanded slave responses. SDO communication is used for setting or
confirmation of objects in the object dictionary. This communication can be used under the
pre-operation, safe-operation, and operation status of the controller.
