8.1 CPU Unit Specifications
Unit type
CPS2R
(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 a
power failure or switching to the PROG. mode, and "non-hold type", which resets the 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 (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.
(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) CPS4R* and CPS3R* can be used by attaching an optional battery. 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. 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, it can be activated
by the internal capacitor even without a battery. For CPS4R*/CPS3R*, approx. one week. For CPS2R,
approx. two weeks.
