4. Begin Period: Set the installment payment to start from the first period, the range is 1-13;
5. List: Configure a list based on [Maximum Periods] and [Begin Period],where user can configure the password and expiration time for each period.
6. Use admin key: It is independent password, and all the expired password can be unlocked by it. If you check it, the installment function would be disabled after you input the admin key. The key can be a combination of "A~z", "a~z" and "0~9"(case-sensitive).

Dynamic mode

To enable the function of the installment payment, you must set up the following parameters

1. Password: Each project installment has a unique identifier. The expiry password is calculated according to password and due time.
2. Current time: Select time due for the first time on the time interface.
3. Expiry time: Display the current PC time (cannot set)
4. Valid days: According to the due time and current PC time, system would automatically calculate the number of days (cannot manually modify). 

 It is configured as following: 

1. Password key is 123456, and the first expiration time is 2021.07.18. 
2. When the HMI system time reaches 2021.07.18, the HMI will pop up the password interface.
3. At this time, you could use the "Password Tool" under the toolbar as shown in following picture, where the installment password needs to be the same as the one when it is downloaded to the HMI, such as 123456. 
4. Assuming that the next expiration time is set to 2021.07.18, the generated password is "5e9035ef". 
5. After entering this password on the password interface, HMI automatically recognizes that the next expiration time is set to 2021.07.18.

Operating Procedure

1. Open "Project Settings" windows.
2. Open "Installment" sub-windows.
3. Select "Static mode" or "Dynamic mode".

2. Set Bit: Set bit when HMI displays the installment screen.
3. Clear Bit: Clear bit when user enters the right installment password.
4. Upcoming Alert: HMI show the installment alert before expire date (before 1,3 or 5 days)

✎Note:

1. The screen of setting intallment and enter password is the built-in sub-screen, and couldn't bue modified.
2. If the HMI system time exceeds the staging time, the HMI will pop up the staging password input screen at 12 o' clock on that day. The HMI can be used normally only after the password is entered. Otherwise, the screen of entering the password is displayed all the time.
3. If the installment function is enable, if you download the project, the current PC time would update to the HMI. The time judgment is based on the system time of the HMI. If the system time of the HMI is modified, the due time of the installment payment will also change, so there is no need to worry about the customer modifying the system time and then delay the due time of the installment payment.
4. You could set the installment on HMI. Add the object "Function switch" on the project and select "installment configuration", then you could set it on the HMI.
5. The password cannot exceed 6 characters. The password can be composed of three modes: numbers, letters, and Chinese characters. Chinese characters contain only three characters and letters are case sensitive. The three key modes can be mixed.
6. Each key corresponds to a admin key. After entering the admin key in the installment password interface pop up by HMI, the installment function will be turned off, that is, the installment password interface will no longer pop up. So you should not use the admin key at will, or open up the admin key to others.
7. In the dynamic mode of installment payments, select "Enable valid period for password", then the "valid days" must be the same day as the current time of HMI.  If the time is not the same day, then the generated password is invalid.
