2. The DIP switch is not used to set the display language with CS1-H CPU
Units. The language is selected on the startup display on the Programming
Console.
3. The CPU Unit will not enter any mode except PROGRAM mode after back-
ing up data to a Memory Card using DIP switch pin 7. To enter RUN or
MONITOR mode, turn OFF the power supply, turn OFF pin 7, and then re-
start the PLC. This will enable changing the operating mode as normal.
The memory of CS-series CPU Units is configured in the following blocks.
• I/O Memory: The data areas accessible from the user program
• User Memory: The user program and parameter areas (See Note 1.)
The above memory is backed up using a CS1W-BAT01 Battery. If the battery
voltage is low, the data in these areas will not be stable.
With the CS1-H CPU Units, however, the CPU Unit has a built-in flash mem-
ory to which the user program and parameter area data is backed up when-
ever the user memory is written to, including data transfers and online editing
from a Programming Device (CX-Programmer or Programming Console, data
transfers from a Memory Card, etc. The user program and the parameter area
data will be held when using a CS1-H CPU Unit.
The internal flash memory of CS1-H CPU Units with unit version 3.0 also con-
tains a comment memory and FB program memory area. The comment mem-
ory is used to store symbol table files, comment files, and program index files
(if comment memory is selected as the transfer destination when transferring
projects from a CX-Programmer Ver. 5.0). The FB source memory area is
used to store function block program data.
