21. Definitions and terminology
The major terminology used in this Operation Manual is stated below.
Terminology Definition
C
Communication
speed
Data transmission speed of a network such as a Fieldbus network.
The speed is determined by upper devices (PLC etc.). The unit is bit
per second (bps).
Communication cycle
time This is a cycle of sending data from masters to slaves (JXCEH
controller).
E
ESI file
Allows a device to be configured for an EtherCAT network, using PLC
setting software.
The file describes data exchange, the slave information and supported
EtherCAT features.
EtherCAT ID
This is the ID number that is used to identify each slave on the
EtherCAT network.
Ethernet
The most commonly used LAN technology that was standardized by
IEEE802.3
F
Fieldbus
An industrial communication system, which uses a defined protocol to
transfer data between devices on a network. A typical automation
system will use a fieldbus network to exchange data between a PLC
master and the actuators/sensors.
P
PLC
Abbreviation of Programmable Logic Controller, a digital computer
used for automation of electromechanical processes.
T
Topology
Connection configuration of the Fieldbus network
Expresses how each terminal and control components are connected.
The typical topology is star type, linear type and ring type.
