8.1 CPU Unit Specifications
Types of operation devices
Counters (C), Counter set values (CS), Counter elapsed values
(CE), Error alarm relays (E)
Inputs (X), Outputs (Y), Timers (T), Timer set values (TS),
Timer elapsed values (TE), Pulse relays (P), Direct inputs (IN),
Direct outputs (OT), Index registers (I), Unit memories (UM),
System data registers (SD)
(Note 3) Direct inputs (IN), direct outputs (OT), and unit memories (UM) are used by specifying unit slot
numbers and memory addresses to be controlled by instructions.
(Note 4) The number of usable data registers (DT) varies according to the type of CPU and memory
configuration settings. However, data registers (DT) that can be used as hold type are a maximum of
262,144 words (DT0 to DT262143) for CPS4R*/CPS3R*, and a maximum of 131,072 words (DT0 to
DT131071) for CPS2R.

Description
Turns on when a self-diagnosis error occurs. Self-diagnosis error codes
are saved in the system data register SD0.
Turns on when a unit alarm is detected. The slot number of the unit
where an alarm has occurred is saved in the system data register SD1.
Turns on when a unit error is detected. The slot number of the unit where
an error has occurred is saved in the system data register SD2.
Turns on when a unit warning is detected. The slot number of the unit
where a warning has occurred is saved in the system data register SD3.
Turns on when an I/O verification error is detected. The slot number of
the unit where an I/O verification error has occurred is saved in the
system data register SD4.
Turns on when a unit installation error is detected. The slot number of the
unit where an I/O verification error has occurred is saved in the system
data register SD5.
Turns ON when an inconsistency is detected in memory configuration.
The setting where an error has occurred is saved in the system data
register SD6.
Turns on when an operation error occurs after the unit has started
operating, and remains on while the unit operation continues. The PB
number where an error has occurred is saved in the system data SD7,
