22. 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. The speed is
determined by the upper device (PLC etc.). The unit is bits per second
(bps).
Communication cycle
time
This is the cycle for sending data from master to slave (JXCL1
controller).
D
Data Storage
This is a function to store the IO-Link device parameter settings to the
IO-Link master.
With the IO-Link data storage function, the IO-link device can be
replaced easily without re-setting the parameters.
Device ID
ID specified for each IO-Link device.
Each product number has its own device ID.
The product number for a controller is different depending on the
mounting method or connected actuator, but the device ID is common.
Device Parameter
One of the ISDU parameters for IO-Link protocol specifications for
which the order and contents are predetermined.
Direct Parameter
Parameter which can easily be accessed in IO-Link communication.
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.
I
IODD
IODD (I/O Device Description)
Device Definition file to provide properties and parameters to establish the
functions and communications of an IO-Link device.
IODD includes the main IODD file and a set of image files such as vendor
logo, device picture and device icon.
ISDU parameter
IO-Link communication parameter which is accessed non-periodically.
In the JXCL1 controller, device parameters and actuator parameters
and step parameters are designated for an SMC product.
P
PLC
Abbreviation of Programmable Logic Controller, a digital computer
used for automation of electromechanical processes.
Process data
Periodically communicated data using IO-Link communication.
This process data enables the operation of the actuator control flag and
provides numerical instructions, and will confirm actuator conditions
including the position.
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.
V
Vendor ID
ID to indicate the manufacture of the IO-Link device. This is controlled
by the IO-Link community. The SMC vendor ID is 0x0083.
Trademark
The company name, system name, and product name described in this document are registered
trademarks of each individual company. In this document TM and (R) are not specified.
