Abbre-
viation
--- Status for indicating information on errors that occur in an application
on a slave.
CoE A CAN application protocol service implemented on EtherCAT.
CiA CiA is the international users' and manufacturers' group that develops
and supports higher-layer protocols.
ESC A controller for EtherCAT slave communications.
ESI An XML file that contains setting information for an EtherCAT slave.
ESM An EtherCAT communications state machine.
--- A standard interface for 1:1 (point-to-point) connections with sensors,
actuators, or other devices as defined in international standard IEC
61131-9.
--- A code for an error detected by an IO-Link device.
--- Communications that use the IO-Link protocol.
--- A device with a sensor or actuator that can perform IO-Link communi-
cations with the IO-Link master. IO-Link devices are simply referred to
as "devices" in IO-Link specifications, but in this manual "IO-Link" is
added to distinguish these devices from other communications devices.
The setting information to verify the configuration when IO-Link devices
are connected.
--- Information on the connection configuration of the IO-Link devices that
are actually connected to the IO-Link Master Unit.
--- A device such as a sensor or actuator that cannot perform IO-Link
communications. It exchanges signals with the IO-Link master in SIO
(DI) Mode or SIO (DO) Mode. In this manual, this term may also be de-
scribed as "non-IO-Link external device".
--- A device such as a sensor that cannot perform IO-Link communica-
tions.
--- A device such as an actuator that cannot perform IO-Link communica-
tions.
--- A device that communicates with the IO-Link devices in the IO-Link
System and simultaneously communicates with the Controller through
the network. "IO-Link Master Unit" is used to refer to a specific Unit.
--- One of the communications mode settings. In this communications
mode, IO-Link communications are performed with the IO-Link devices.
--- A logical interface that is used by the NJ/NX-series CPU Unit or NY-
series Industrial PC to exchange data with an external device (slave or
Unit).
--- Settings that assign variables to I/O ports. Assignment information be-
tween I/O ports and variables.
--- Cyclic data exchange with external devices that is performed with pre-
determined memory addresses.
--- An acronym for process data communications.
--- One type of EtherCAT communications in which service data objects
(SDOs) are used to transmit information whenever required.
