The CPU Unit’s internal clock is not set when the CPU Unit is shipped. Be sure to
set the clock with a Programming Device. Refer to the Programming Device’s
Operation Manual for details.
Before using the CVM1D, clear the Error Log Area by force-setting (forcing ON)

CVM1D Program Memory
Program Memory is contained in the CPU and is divided into two areas, the PC
Setup and the Program Area. There are 64K words available in the CVM1D. The
first 2K words are taken up by the PC Setup, leaving 62K words in the Program
Area. (One word contains two bytes.)
Program Memory is backed up by the CPU battery, so data will not be lost during
a power interruption.
Note The program memory chip is built into CVM1D PCs and does not need to be
installed by the user.
This area of Program Memory contains the settings described in Section 7 PC
Setup. Basic options in PC operation (such as the method of I/O refreshing and
the PC mode at start-up) are specified in these settings.
The PC Setup is stored in EEPROM, so this data will not be lost even if the back-
up battery power is interrupted.
This area of Program Memory contains the ladder program. There are approxi-
mately 60K words available for the ladder program because 1.85K words are
reserved for system use.
