Term Description
A
Address
Number showing the address
For the S-LINK V system, this number should be set for each I/O unit.
B
bit
Contraction of 'binary digit.' Binary numbers will be set for bits. In other words, '0' or '1' will be set for
each bit.
bps Abbreviation of 'bit per second.' This is a unit showing how many bits can be sent in 1 second.
Branch line Line branched from the main line
C
Cabtyre cable Cable consisting of several insulated wires that are covered with a strong sheath
CHECK mode
In this mode, you can check the I/O unit recognition conditions using the controller. If operation is
performed in the CHECK mode, transmission with the I/O units will be carried out, and the I/O signals
will be refreshed just like the RUN mode.
Common (COM.) Common (COM.) Line [+24V = COM. (+), 0V = COM. (-)] common to controller and I/O units
CONFIG mode
In this mode, you can set the transmission mode, number of I/O control points, and error output op-
eration. In addition, system setting and default setting are possible in this mode.
However, various settings and default setting are possible in the CONFIG mode just after power-on only.
During operation in the CONFIG mode, transmission with the I/O units will not be performed.
This means that refreshing of I/O signals will not be carried out.
Connector cap This cap is attached to the end of each PLC I/O connector.
Connector number Number assigned to each PLC I/O connector ( SL-VS □, SL-VP □)
CPU module PLC module having the functions of the central processing unit (CPU)
D
DIN rail This rail conforms to the DIN EN 50022 German industrial standards.
E
Error number Code indicated by the controller after detection of an error
Error output
Signal output from the controller after detection of an error
The output terminal can be changed using the controller.
Exclusive (4-core) flat cable
SL-RCM □. The exclusive (hook-up) connectors can be used. This is a flat cable having 4 cores and
cable conductor cross section of 0.5mm
2
.
Exclusive (hook-up) connector
Exclusive (hook-up) SL-J □, SL-CP □, and SL-CJ □
If you use this connector and exclusive tool, wiring can be easily performed.
F
Failsafe
Design adopted for the system to ensure safety even if the system performs abnormal operation or
malfunctions
H
Hexadecimal number Hexadecimal number expressed by numbers 0 to 9 and alphabetic characters A, B, C, D, E, and F
Hook-up connector SL-J□ , SL-CP□ , SL-CJ□ , etc.
I
Interference between signals
Interference between signals also referred to as crosstalk or collision. This is a problem caused by
an undesirable signal sent from the other transmission line.
Interlock
Method to prohibit the entire or partial machine operation in order to ensure safe operation of the
system or machine and to prevent accidents until certain conditions are met
Isolation
(Photo-isolation)
To electrically separate the external circuit from the internal circuit using a photo-coupler, etc. in order
to reduce the influence of external noise in the I/O area
L
Leakage current Electric current that flows through the output area in the output OFF mode
LED Abbreviation of 'light emitting diode.' This diode will emit light if electric current flows through the diode.
M
Main line Longest route from the controller to the line end
Maximum transmission
distance
Maximum main line length controllable for the controller. This length depends on the transmission
mode, number of nodes, and conductor cross section of the transmission cable.
Maximum load current (Output sink
current)
Maximum current used by the output unit
