Device list

Device means a general name for such as a contact, coil and timer used on the program
operations in a programmable controller.
The following shows usage ranges and device names of the programmable controller.
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 assignment.
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".)

Device list
A2SHCPU(S1)
Used for the supply programmable controller commands and data
A2SHCPU:
from the external devices such as push buttons, select switches,
X/Y0 to X/Y1FF
limit switches and digital switches.
(512 points)
A2SHCPU-S1:
Used for the output control results of the program to the external
X/Y0 to X/Y3FF
devices such as solenoids, magnetic switches, signal lights and
(1024 points)
digital display device.
• Possible to use in a program from the I/O points usage range for
each PLC (described above) up to 2048 points.(External output
is not allowed.)
• Allocates for remote I/O of MELSECNET(B) and for auto refresh
of CC-Link.
An auxiliary relay that is used in a programmable controller set in
advance for a special application.
An auxiliary relay in a programmable controller that cannot output
directly to external devices.
An auxiliary relay in a programmable controller that cannot output
directly to the external devices. Has the power failure
compensation function.
Used in the same manner as the internal relay (M).
Used as a relays to indicate the stage number of process stepping
program, etc.
An internal relay for data link. Cannot output to external
devices.The range not set by the link parameters can be used as a
substitute for a data register.
For error 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.
Up-timing-timer. There are three kinds: 100ms timer, 10ms timer
and 100ms retentive timers.
Up-timing
There are two kinds: up-timing counter used in programmable
controller programs, interrupt counter used in counting the number
of interrupts.
Memory that stores data inside the programmable controller.
Data memory set up in advance for the special application
Register for a data link
The range not set by the link parameters can be used as a
substitute for a data register.
