3.6.2.5 Assign password via SIMATIC Memory Card
If you want to transfer the password to protect confidential PLC configuration data to a CPU
without using TIA Portal, you can also use a SIMATIC memory card for this function.
The use of a SIMATIC memory card is suitable for the following purposes:
•
Preparing a new CPU
If a CPU is set up again, it should be configured with a password to protect the
confidential PLC configuration data. After this configuration is completed, it is possible to
use another SIMATIC memory card with the desired project.
(S7-1200 CPU: A "transfer" card with transfer job can also be used to install the program
on the CPU).
• CPU has a password to protect confidential PLC configuration data, but the password does
not match the project
If the passwords are not identical, you can set the correct password with the memory card
in the CPU.
(S7-1200 CPU: equipped either with SIMATIC "transfer" card or with SIMATIC "Program"
card).
• reset the password for the protection of confidential PLC configuration data in the CPU
As preparation for a disposal of the CPU or as preparation for a new project for the CPU.
Requirement
• TIA Portal as of version V17
