(Note 1) The program capacity, data register capacity and maximum number of program blocks (PBs) vary according
to the type of CPU and memory configuration settings. They are set from the configuration menu of tool
software FPWIN GR7. The default values are pattern 3 for CPS4 and pattern 1 for CPS3.

CPS4*
CPS3*
(Note 2) Figures in the table indicate the number of devices that can be used in the program. The actual inputs and
outputs that can be used vary by configuration.
(Note 3) Operation devices are categorized into "hold type", which memorizes the status immediately before power
failure or switch to the PROG. mode, and "non-hold type", which resets such status. Internal relays, data
registers, link relays and link registers can be set as non-hold type or hold type by the tool software. Counters
and error alarm relays are hold type. Other operation memories are non-hold type. However, data registers that
can be used as hold type are a maximum of 262,144 words.
(Note 4) 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 5) Battery lifetime: 3.3 years or more, suggested replacement interval: 5 years.
After power is supplied to the CPU unit for 30 minutes or longer, data can be retained for approx.one week by
the internal capactitor even without a battery.
(Note 6) Precision of the calendar timer (real-time clock): Difference less than 95 seconds per month (0C), less than
15 seconds per month (+25C), less than 130 seconds per month (+55C).
When the unit is connected to ET-LAN, the time is synchronized by the SNTP function.
