EtherCAT® - State machine
Both the master and the slaves have a state machine with the states shown below. After
boot the slaves are in INIT state, and then it's up to the master to request state transi-
tions. The standardized EtherCAT® state machine is defined in the following figure. The
bootstrap state is not supported.
The module enters the Init state directly after start-up. After this, the module can be
switched to the Pre-Operational state. In the Pre-operational state the EtherCAT® mail-
box communication is allowed and CoE objects can be accessed by SDOs. After the mas-
ter has configured the slave, it can switch the module to the Safe-Operational state. In
this state input I/O data (PDOs) is sent from the adapter module to the EtherCAT® mas-
ter, but there is no output I/O data from the master to the module. To communicate out-
put I/O data the master must switch the adapter module to the Operational state.
State description table:
State
Description
Init
State after device initialisation. No Application layer communication (no SDO and
PDO communication).
Pre-operational
SDO communication possible. No PDO communication.
Safe-operational
Transmit PDO operational (drive sends data to master)
Operational
Drive fully operational, responds to data via receive PDO
Boot-strap
Not used.
