====== Module-based Models Firmware Updating Instruction ======

===== Tools Preparation =====
  * A laptop or table PC.
  * One FAT32 formatted USB disk. Smaller than 16GB.Newer disks may NOT be recognized.
  * Firmwares: <WRAP group>

The U2 is the center control board referred in the communication protocol file.

===== Before updating =====
<WRAP center round important 60%>
Make sure the inverter is **NOT** running.

Updating priority sequence, unless informed by us: 
  - HMI, 
  - AC modules, 
  - U2.

If the menu on top of the screen seems less than shown below, it indicates that the system has been set to remote control mode.
</WRAP>

  -   Select **Ctrl mode -> Local Manual** to show the complete menu.
  -   Remember to switch back to remote control after the updating operations.
  -   Login as super administrator with super password\\  \\ {{:manual:image001_control_mode.jpg|}}
  -   Check **System -> module** on the HMI, whether the information conforming to actual configuration. 
  -   Check the ACPCU U1 DSP versions in **info -> AC details**, HMI version is in the left bottom of the screen.
  -   Change AC module number from 1 to 2/3/4/5(depending on the actual module quantity), if you can read the parameters, it means the module is online. Select **AC module 11**, you will read the U2 DSP version.\\  \\  {{:manual:image002_readdversion_.jpg|}}
  - Double check and make sure all modules are online in ** Info->Status**.\\  \\   {{:manual:image003_info_status.jpg|}} \\   
<WRAP center round tip 60%>
Since V1330, even if the module is indicated "Offline" due to the module firmware version is too new or too old for HMI to communicate, you can still update it.
</WRAP>



===== Updating HMI =====

{{:manual:image004_usb_slot_back_of_hmi.jpg|}}

  - The PCS should be powered off from both AC and DC supply.
  - Copy the HMI firmware file monitor.tar.gz into the USB disk, plug the USB disk to the USB port of the HMI (open the front door).
  - Power on the PCS from AC.
  - When HMI starting up, it will load the updating file and do the updating automatically. You will hear a "beep-" sound.
  - Wait until it stops on Home page, it will feel like nothing happened. But the version in bottom of the HMI should have changed
  - Unplug the USB disk, delete the HMI file monitor.tar.gz

==== Legacy content before HMI V1330 ====

<WRAP center round important 60%>
In HMI version 1330 or earlier, the **Updating** page is not available in English, you have to log in with an operator password and change the language to Chinese. You can check the following 4 English-Chinese comparing figures to find how to change it back to English again.

Login and then you can see all the menus.

In HMI version 1340 or later, the **Updating** page is English.

===== Updating AC module =====
Open the front door, plug the USB disk to the USB port of the HMI


<WRAP center round important 60%>
Make sure that the HMI firmware: monitor.tar.gz, is **NOT** in the USB disk at this moment
</WRAP>

  - Enter the **Upgrade** page in Settings. 
  - Select Type as **DCAC**, and **Module**
  - Check all the modules that need to be updated
  - Click **Import**, to load proper .hex file, named AC_U1_V[version].hex;
  - Click **Upgrade**, then input the password 123456；
  - Wait until the progress bar reaches 100%, updating completes. 
  - Hard rebooting is requested before the new firmware works. 
  - After the hard reboot, check whether the versions are right in **Info -> AC details**.
  - If any warning notes that updating failed, jump to [[#Exception procedure in case of failure]]
  - May you never need to refer to [[#Exception procedure in case of failure]]

To UPDATE U2 Firmware, just repeat the procedures above, the differences are:
  - Select **Type** as U2
  - Check on #11
  - Click **Import**, Select U2_V[version].hex

===== After Updating =====
<WRAP center round important 80%>
Before leaving the site, DO remember to set the HMI to **Remote Control mode** if it was not in this mode!
</WRAP>


===== Exception procedure in case of failure =====
If any failure happened in updating operations, plug the USB disk in the USB port of the HMI

<WRAP center round alert 60%>
DELETE the HMI updating file BEFORE PLUGGING!
</WRAP>

follow the following flow chart.

<flow>
graph TD;
    A(Start)-->B["Update U2 (#15)"];
    B-->C{U2 updating success?};

</flow>

If the internal communication failed, the updating flow chart must be strictly followed. The first step is always updating U2-15#. And a hard reboot is necessary, remind the firmware version of the U2.
After updating failure, the updating must be implemented one module by one module, and the ID is always 15#, and every time there should always be one module plugged with comm plug.

===== How to apply customized LOGO to HMI =====

Prepare the LOGO file and copy it to the root directory of the USB disk. The LOGO file should conform to the following requests,
  * .PNG format
  * Transparent background
  * Height 46 pixels (best performance, lower height can also work but may not be symmetry), the width can be determined by the logo itself.
  * Named as logo.png
Switch control mode to Local manual if necessary. Login as super administrator with password , 
Plug the USB disk to the USB port of the HMI.
Click ** Settings -> Local -> change logo**.

 {{:manual:image010_compare_en_settings_upgrade.jpg|}}

A dialog box will remind to reboot to take effect.
Hard reboot the ACPCU and the Sinexcel LOGO will be replaced by the new LOGO.
