Note
The following data will be write-protected if pin SW1 is turned ON:
• The entire user program (all tasks)
• All data in parameter areas (such as the PLC Setup)
When SW1 is turned ON, the user program and the data in the pa-
rameter areas will not be cleared even if the All Clear operation is
performed from a Peripheral Device (i.e., the CX-Programmer).
(8)
Built-in Analog I/O Terminal Block and Terminal Block Base (XA CPU
Units Only)
There are four analog inputs and two analog outputs.
Mount the terminal block (included with the CPU Unit) to the terminal
block base. (Refer to 5-5 Analog I/O (XA CPU Units).)
(9)
Built-in Analog Input Switch (XA CPU Units Only)
This DIP switch determines whether each analog input is to be used for
voltage input or current input.
Note
The built-in analog input switch is located on the PCB inside the case. To
make setting the switch easier, make the switch settings before mounting the
terminal block to the base.
While setting this switch, be very careful not to damage the wiring on the PCB.
(10) Memory Cassette Slot
Used for mounting a CP1W-ME05M Memory Cassette. When mounting
a Memory Cassette, remove the dummy cassette.
Data, such as CP1H CPU Unit programs, parameters, and data memory,
can be transferred to the Memory Cassette to be saved.
SW5
ON
Used for peripheral
bus.
Used to enable a Serial
Communications Option
Board mounted in Option
Board Slot 2 to be used
by the peripheral bus.
OFF
