Selecting a Password for the TD Device
Selecting a password for the TD device helps you to protect the security of your process or
application. By enabling a four-digit password (from 0000 to 9999), you can control access to
the S7-200 CPU by requiring that an operator enter the password before editing variables
from the TD device.
The TD password also restricts access to the following TD functions:
● Set time and date
● TD Setup
● Forcing I/O
● Changing the CPU mode
● Creating a memory cartridge
● Editing CPU memory
Tip
The TD password affects only the ability of an operator to use the TD device for certain
functions.
If your S7-200 CPU is configured to require a password, the operator must enter the CPU
password to force I/O and create a memory cartridge. The TD password is used in addition
to the CPU password.
Enabling the TD Menu Functions
You can select the TD functions that appear on your TD device menu. The TD devices have
different functions available. Refer to Chapter 5 for information about these CPU functions.
