A CAN application protocol service implemented on
EtherCAT.
CAN in Automation
CiA
CiA is the international users’ and manufacturers’
group that develops and supports higher-layer proto-
cols.
Device Profile
---
Collection of device dependent information and func-
tionality providing consistency between similar
devices of the same device type.
Distributed Clocks
DC
Method to synchronize slaves and maintain a global
time base.
EtherCAT Slave Controller
ESC

Users and Technology Providers join forces to sup-
port and promote the further technology develop-
ment.
Fieldbus Memory Management Unit
FMMU
Single element of the fieldbus memory management
unit: one correspondence between a coherent logi-
cal address space and a coherent physical memory
location.
Index
---
Address of an object within an application process.
Object
---
Abstract representation of a particular component
within a device, which consists of data, parameters,
and methods.
Object Dictionary
OD
Data structure addressed by Index and Subindex
that contains description of data type objects, com-
munication objects and application objects.
Physical Device Internal Interface
PDI
A series of elements to access data link services
from the application layer.
Power Drive System
PDS
A power drive system consisting of a Servo Drive, an
inverter, and other components.
Process Data
---
Collection of application objects designated to be
transferred cyclically or acyclically for the purpose of
measurement and control.
Process Data Object
PDO
Structure described by mapping parameters that
contain one or several process data entities.
Receive PDO
RxPDO
A process data object received by an EtherCAT
slave.
Ring disconnection status
---
A status in which communications continue even if
an EtherCAT physical layer link is disconnected in a
ring topology on the EtherCAT system.
safe state
---
The status of a device or piece of equipment when
the risk of danger to humans has been reduced to an
acceptable level.
