22. Definitions and terminology
The major terminology used in this Operation Manual is stated below.
Terminology
Definition
A
Address
Numbers assigned to identify the unit which is connected to a
DeviceNet network. They do not allow to be overlapped.
B
Bus off
Error is detected when sending/receiving over DeviceNet, and sending
and receiving message is stopped.
C
Communication
speed
Data transmission speed of network such as Fieldbus 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 (JXCD1
controller).
F
Fieldbus
Network protocol to transmit digital signals between automated
industrial system such as measurement tool or manipulator and PLC.
P
PGM
The address and communication speed can be changed over
DeviceNet communication by setting the switch to PGM (64-99).
PLC
Abbreviation of Programmable Logic Controller. A digital computer
used for automation of electromechanical processes.
T
Terminating resistor
Resistors mounted onto both ends of the wire when equipment is
connected to the fieldbus. They avoid signal reflection at the terminals
and turbulence of the signal.
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.
