One built-in peripheral port (USB 1.1): For connecting Support Software only.

A maximum of two Serial Communications Option Boards can be mounted.

A maximum of two Ethernet Option Boards can be mounted. When using CP1W-CIF41
Ver.1.0, one Ethernet Option Board can be mounted.

Flash memory: User programs, parameters (such as the PLC Setup), comment data,
and the entire DM Area can be saved to flash memory as initial values.
Battery backup: The Holding Area, DM Area, and counter values (flags, PV) are backed up
by a battery.

5 years at 25C. (Use the replacement battery within two years of manufacture.)
