Program Protection
Section 6-7
9.
Turn the power supply to the CPU Unit back ON.
Note
After the automatic transfer from the Memory Cassette at startup has been
completed with the operating mode after automatic transfer at startup set to
PROGRAM mode (default), the transfer will not start again automatically
(regardless of the Startup Mode setting in the PLC Setup). As described in the
procedure above, to start operation turn the power supply OFF, return the set-
ting of DIP switch SW2 to OFF, and then turn the power supply back ON. If the
the operating mode specified in the PLC Setup is set as the operating mode
after automatic transfer at startup, operation will start without changing the
DIP switch SW2 or Memory Cassette.
Operating from a
Memory Cassette

1.
Prepare a Memory Cassette containing the required data.
When transferring the data to the Memory Cassette, set the operating
mode after automatic transfer at startup to PROGRAM mode (default).
2.
With the power supply turned OFF to the CPU Unit, remove the cover from
the Memory Cassette slot and insert the Memory Cassette.
3.
Open the cover for the CPU Unit's PERIPHERAL section and set DIP
switch pin SW2 to ON.
4.
Turn ON the power supply to the CPU Unit.
Note
If, when the data is transferred to the Memory Cassette, the operating mode
specified in the PLC Setup is set as the operating mode after automatic trans-
fer at startup, operation will start automatically after data transfer, even if the
power is not cycled. Be sure that starting operation will cause no problems
before using automatic transfer at startup.

Program Protection
The following protection functions are supported by the CP1L CPU Units.
• Read protection from the CX-Programmer
• Write protection using a DIP switch setting
• Write protection setting from the CX-Programmer
• Write protection against FINS commands sent to the CPU Unit via net-
works
• Prohibiting creating a program file for file memory
6-7-1
Read Protection
Overview
It is possible to read-protect individual program tasks (called task read protec-
tion) or the entire user program (called UM read protection).
Read protection prevents anyone from displaying or editing the read-protected
set of tasks or entire user program from CX-Programmer without inputting the
correct password. If the password is input incorrectly five times consecutively,
password input will be disabled for two hours, providing even better security
for PLC data.
