Introduction
The DeviceNet functionality and configuration options can be changed and parameterized depending on the different EtherCAT states.
EtherCAT states
The EtherCAT states (INIT, PREOP, SAFEOP, OP) have the following meaning according to the fieldbus-specific functions:
|
EtherCAT state |
Meaning |
|---|---|
|
INIT |
Fieldbus not running |
|
PREOP |
Load fieldbus configuration |
|
SAFEOP |
Fieldbus cyclic operation, safe state. Inputs are read, outputs are not written |
|
OP |
Fieldbus cyclic operation. Inputs are read, outputs are written |
The procedure and the configuration options are described below
