JP4 is located above the motherboard CPU, with empty terminals and no connectors, only two pads. After short circuiting it, enter the parameter settings, confirm the factory password of 8888, and then modify the parameters after F00.
How to encrypt your frequency converter parameters
If you want to protect your frequency converter parameters from illegal reading or modification, can you add a software lock to the parameters? (Evade everyone, I'm about to start Amway!)
The answer is: Of course! Sinamics frequency converter comes with encryption function - proprietary technology protection function. Not only G130/150, but also G120, as well as other Siemens frequency converter products that can be debugged using Starter, you can also draw inspiration from them.
Below we will introduce the specific usage:
1： How to activate the proprietary technology protection function?
Step 1. Create a list of special cases that do not fall within the scope of proprietary technology protection
Through a special list, machine manufacturers can set some setting parameters that are not within the scope of proprietary technology protection, that is, end users can still access these parameters when the protection is activated. The special list can be defined through the parameters p7763 and p7764 in the expert parameter table. P7763 is used to determine the number of parameters included in the special list (non encrypted parameters). P7764 is used to determine the parameter number.
Creation steps:
1. By uploading（
））Save the frequency converter settings on PC or PG and enter offline mode（
）
2. Set p7763 in the project to the desired value on the PC. Save the project.
3. Enter online mode and load the project into the frequency converter（
）
4. Then continue to set other exception parameters in p7764.
Factory default settings for special lists:
P7763=1 (containing only one parameter)
P7764 [0]=7766 (exception parameter)
Attention: Be extremely careful when creating a special list! After you remove p7766 from the special list, you can no longer enter a password and cancel proprietary technology protection. The only way to access this parameter in the frequency converter again is to restore the factory settings of the frequency converter
Step 2, activate proprietary technology protection function in the Starter project
1. Click the left mouse button and select the frequency converter in the STARTER project
2. Click the right mouse button to open the right-click menu and select 'Drive Unit Know now Protection'.
3. Click to activate proprietary technology protection "Activate"
4. Click on 'Specify' in the dialog box and enter the password,
5. Click "OK" to confirm.
The encrypted parameter list using proprietary technology protection function is purple: unauthorized reading and writing of all illegal parameters will not be implemented. For BOP-2, IOP, BOP20, AOP30 and other panel equipment, protection is equally effective
2： How to cancel the proprietary technology protection function?
1. In the STARTER project, select the frequency converter and select "DriveUnitKnow now" from the right-click menu
Protection.
2. Select deactivate.
3. Select 'Temporarily' or 'Permanently' to remove proprietary technology protection.
4. Enter the password and click OK to close the dialog box.
3： How to modify the proprietary technology protection function
1. The frequency converter must be in online mode.
2. Proprietary technology protection must be activated.
3. In the STARTER project, select the frequency converter and select "Drive Unit Know now Protection/Change Password..." from the right-click menu
5. Open the 'Change Password' window.
6. Enter the old password and the new password.
7. Choose whether to execute 'Copy RAM to ROM', which is checked by default.
8. Click OK to exit the window.
9. The new password will take effect.
For PLC program encryption, it is generally used for dishonest customers, but you may not know the customer's integrity beforehand. Therefore, it is recommended to encrypt every program well. For example, if you have a one-year maintenance period, you can choose 1 year and 3 months, which is slightly longer than the maintenance period.
Encryption programs cannot be completely affected by time
For example, if you use date judgment, it may cause date recognition errors due to a prolonged power outage of the PLC. It is recommended to judge the time and record the time every 4 hours. If the time is greater than that time in the next judgment, it is considered an error, and if it is less than that time, it is considered an error. The time will be automatically refreshed or a time tag alarm will be issued. The secret program should not be too rigid
Don't limit the time. As soon as the time comes, you can close the program tightly, which may cause damage to on-site equipment or injury to on-site personnel, resulting in negative effects. You can choose to stop some parts that do not involve personal safety or equipment safety, and then raise an alarm. The alarm type can be that the next time it cannot be started, and the ones that have already been started will continue to run as usual.
The encryption program should be released appropriately
Don't wait until an emergency to go to the scene on your own, set your own trap. You can choose an empty DI point as the release point or perform a special combination operation on-site to release it, but it is best to use the upper computer authorization code.
Attention to authorization codes
Your authorization can be divided into multiple time tags. For example, if some users cannot pay all your fees as agreed, you can use the authorization to extend the operation period by 1 month, 3 months, or half a year, so that users are always subject to your constraints. Of course, you need to do it seamlessly or let the other party's main leader know.
The highest level of encryption - program bombing
The encryption program has been executed, and when encountering stubborn users who delay paying fees, they are no longer polite. The program bombing method is used to delete the main section of the program to avoid other interference. This method requires special PLC support, such as Siemens S7300 or above CPU. Alternatively, use program copying to fill up the space, or issue commands to the upper computer to directly delete the program.
In short, encryption is effective until the establishment of an honest Chinese country. It is best for the PLC to have hardware encryption to prevent Party A from uploading programs to personnel from other companies.
