4.1.5 Device list
Device means a general name for such as a contact, coil and timer used on the program
operations in a PLC.
Usage ranges and device names of the PLC are shown below.
For * in the devices below, they can be used by setting the parameters on each peripheral
device. Also, they can be changed the usage ranges allocation.
Set the parameters depending on the usage system and contents of the programs.
For the detailed setting for parameters, refer to Section 4.2.1 List of parameter setting
range.

X Input
X/Y0 to X/Y3FF
(1024 points)
X/Y0 to X/Y1FF
(512 points)
X/Y0 to X/Y3FF
(1024 points)
Used for the supply PLC commands and data from the external
devices such as push buttons, select switches, limit switches and
digital switches.
Y Output
Used to the output control results of the program to the external
devices such as solenoids, magnetic switches, signal lights and
digital display device.
X Input
X/Y0 to X/Y1FFF(8192 points)
• Possible to use in a program after the I/O points usage range per
each PLC (described above) to up to 8192 points (the external
output is not allowed). (external output is not allowed)
Y Output
• Objective is to allocate for auto I/O refresh of MELSECNET/MINI-
S3, for remote I/O of MELSECNET/10, for remote I/O of
MELSECNET(B), or for CC-Link.
M
Special relay M9000 to M9255 (256 points)
An auxiliary relay used inside a programmable controller set in
advance for a special application.
*Internal relay
M/L/S0 to M/L/S8191 (8192 points)
8192 points as a total of M, L, S
An auxiliary relay inside a programmable controller which cannot
output directly to external devices.
L *Latch relay
An auxiliary relay inside a programmable controller which cannot
output directly to the external devices. Has the power failure
compensation function.
S *Step relay
Used in the same manner as the internal relay (M).
Used as a relays to indicate the stage number of process stepping
program, etc.
R Link relay B0 to B1FFF (8192 points)
An internal relay for data link and cannot output to external devices.
The range not set by the link parameters can be used as a
substitute for a data register.
F Annunciator F0 to F2047 (2048 points)
For fault detection. A fault finding program is created in advance,
and if it becomes ON during RUN, the number is stored in a special
register D.
T
*100ms timer
T0 to T2047 (2048 points)
(Register for storing setting value(s) is required for T256
and later.)
Up-timing-timer. There are three kinds: 100ms timer, 10ms timer
and 100ms retentive timers. *10ms timer
*100ms retentive
timer
C
*Counter
C0 to C1023 (1024 points)
Interrupt counter C224 to C255 fixed.
Register for storing setting value(s) is
required for C256 and later.
Up-timing
There are two kinds: up-timing counter used in programmable
controller programs which counts number of interrupts.
*Interrupt counter
