If any of the above items does not pass a self-test, the following message will be displayed on the screen for about two seconds and then disappeared.

Error code: 0x18

Wait for a minute to continue

If power to the HMI or the PC was interrupted while downloading, the item “Firmware check” or “Application check” will not pass a self-test and will be checked with an “x” mark after power is restored. The situation is normal and users can simply follow the download procedures to re-download an application or data.

After downloading, all items should pass the next self-test.

Warning: To avoid an electronic shock, be sure to switch off the power before connecting the download cable to the HMI.

Set the dip switch SW7=ON. After a self-test, the System Menu will be displayed on the screen and the PWS6300S is ready to download an application.

Open an application file to be downloaded in ADP and make sure that communication parameters are correctly configured. Also remember to compile a file before downloading if not yet. Please note that one needs to compile a file before

downloading or anytime a change has been made in a file.

Next select [Application] / [Download Firmware and Application] in ADP if it is a first time to download an application to the HMI; otherwise, select [Application] /

[Download Application]. The following should appear on the screen while the

PWS6300S is downloading:

Uploading an Application

An application can also be uploaded from the HMI to the PC. Thus, a user can save an application as a *.V6F file in ADP for future use.

Warning: To avoid an electronic shock, be sure to switch off the power before connecting the communication cable to the HMI.

Make sure that the HMI and the PC are connected, shown as in Section _ 6 _. Set the dip switch SW7=ON. After a self-test, the System Menu will be displayed on the screen and the PWS6300S is ready to upload an application.

Also make sure that communication parameters are correctly configured. Select

[File] / [Upload Application] in ADP and the [Save As] dialogue box will appear on the screen. Enter the name of a firmware file (*.AF6) to save. Click [Save].

Then the HMI will prompt a user to ask for a password: enter the password set in

ADP from [Application] / [Workstation Setup]. Once a password is entered, the

PWS6300S starts to upload an application to the PC. (For setting a password,

- 6 -

please refer to Section _ 9 _.) While the PWS6300S is uploading, its screen should appear as the following:

Uploading FW …

Link

After uploading, select [File] / [Reconstruct Source] in ADP and the [Open] dialogue box will appear on the screen. Open an uploaded application file (*.C64 or

*.AA6) and then an application screen will show up in the PC. Finally, select [File]

/ [Save As] to save an application as a *.V6F file. Thus a source file can serve the purposes of maintenance and modification.

Copying

In the System Menu, select F8 – Copy to copy an application from the PWS6300S to the other PWS6300S. Set the dip switch SW7=ON and connect two PWS6300S with a download cable in COM2. After a self-test, the System Menu will be displayed on the screen.

Select F8 – Copy in the System Menu from the PWS6300S with the application to be copied. The HMI will prompt a user to ask for a password: enter the password set in ADP from [Application] / [Workstation Setup]. Once a password is entered, the PWS6300S starts to copy an application to the other PWS6300S. (For setting a password, please refer to Section _ 9 _.) The followings should appear on the screens while the PWS6300S is copying an application to the other:

Setting a Password - 4 Scenarios

- 7 -

Scenario 1: A password is required to start the HMI.

If the dip switch SW6 is ON, then a user needs to enter a password to start the

HMI. For this purpose, the Object - Action Button in ADP is available for a designer to create a button which displays a Password Table on the HMI, so a user with the right of access to the table can register passwords and user’s levels in the table.

Figure 6 is an example to display a Password Table on the HMI; in this example,

button is an action button which displays a Password Table. Select this button and then a Password Table will be displayed on the screen for the user with the right to access the table. Use

? ? ? ? to move and to highlight an area for entering a value. See Figure 7. (For the details on the Action Button, please refer to ADP User’s Manual.)

Figure 6. An example of setting a password

# Password Lv1

1 00000000 1

2 00000000 1 F1:

3 00000000 1 CANCEL

4 00000000 1

5 00000000 1

6 00000000 1 F2:

7 00000000 1 OK

8 00000000 1

Figure 7. Password Table

After registering passwords and user’s levels, set the dip switch SW6=ON (i.e. password required). Restart the HMI and after a self-test a user will be asked to input a password to run the HMI. See Figure 8.

Figure 8. Password required to run the HMI

- 8 -

The HMI will determine a user’s level from a password entered by a user. For instance, if the level of a password entered by a user is 1, then the HMI will set the user’s level=1; if the level of a password entered by a user is 2, then the

HMI will set the user’s level=2. The user’s level 1 has the highest privilege and

- 9 -

Scenario 2: Re-enter a password.

the user’s level 9 has the lowest. Also note that only a user with the user’s level

1 has the right of access to the Password Table.

The Object - Action Button in ADP is also available for a designer to create a button which asks a user to re-enter a password. For example, select button in Figure 9 and then the HMI will prompt a user to re-enter a password.

The HMI will update a user’s level according to the most recent password which has been entered. Therefore, this button can be applied to raise or drop one’s privilege while the HMI is in operation. (For the details on the Action

Button, please refer to ADP User’s Manual.)

Figure 9. The HMI asks for a password.

Scenario 3: A password is asked to execute a button on the HMI.

A designer can design a button which requires a password to execute it. For example, a Goto Screen button can be designed with a high level of security; that is, it will require a password with a high level of privilege. As the button is selected and the current user has a lower privilege than the button which has been set for, the HMI will prompt a user to ask for a password, also see Figure 9.

A user will need a password with at least the level of privilege which the button has been set for. This function can restrict a user to access to certain parts of an application.

Scenario 4: Enter a password to copy or upload an application.

Once F8 – Copy in the System Menu or [File] / [Upload Application] in ADP is selected, the HMI will also prompt a user to ask for a password. A user will need to enter the correct password to copy an application from one HMI to another. Note that this password is different from those passwords set in

Scenario 1~3. To set this password, select [Application] / [Workstation Setup] in ADP. On the [Password] tab, a designer is then able to set the password.
