Using Gestures on Client Portable Devices

Google Chromebooks

Plant SCADA Access Anywhere operates on Google Chromebook and Chromebox just like it does with a Google Chrome browser. Here are some tips to keep in mind when using Access Anywhere with a Chromebook or Chromebox.

Chrome Keyboard

The Chromebook keyboard lacks several keys that are used by Windows. ChromeOS provides standard mappings that use existing keys with the ALT button to represent certain missing keys. Plant SCADA Access Anywhere supports these key combinations:

In addition, Plant SCADA Access Anywhere provides special non-standard mappings for additional key combinations on ChromeOS.

Tablet and Smartphones

Plant SCADA Access Anywhere can operate on tablets or smartphones with an HTML5 compliant browser (see list of browsers in Plant SCADA Access Anywhere Readme). Browser versions that have been tested and their specific behaviors are detailed in the Plant SCADA Access Anywhere Web Client User Guide.

When you design Plant SCADA clients for use with Plant SCADA Access Anywhere, remember that touch devices have different interface requirements and capabilities than a keyboard and mouse. For example, input animations should not invoke a Plant SCADA or Windows keyboard, as mobile devices have their own.

With existing AVEVA Plant SCADA clients that make use of mouse events and keys or key combinations without a supported equivalent, you may want to modify your application to use alternate application events.

The following list provides gestures available when using Plant SCADA Access Anywhere from a tablet or smartphone device where a physical keyboard and mouse is not available. Functionality will vary across different devices and certain commands may not be available.

• Single Tap performs a left click.

• Single long Tap performs a right-click.

• Tap + Hold + Drag performs a select then drag/scroll function.

• Double Tap, or tapping once with two fingers, performs double-click.

• Tap with three fingers sends Back command to a remote browser.

• Swipe down with three fingers is Page Up.

• Swipe up with three fingers is Page Down.

• Drag left or right with three fingers performs a left arrow and right arrow respectively.

• Tap the keyboard icon (upper right-hand corner of window) to open/close the virtual keyboard.

• Swipe and pinch gestures will apply to the Plant SCADA Access Anywhere session (i.e. zoom in with pinch in).

• (iOS only) When saving a Plant SCADA Access Anywhere icon to the iOS desktop, the shortcut will open the Plant SCADA Access Anywhere session full-screen mode. The browser’s toolbar will be hidden and there will be more remote desktop area available.

HTTPS Mode

For environments where WebSockets support is not available, Plant SCADA Access Anywhere can work in HTTPS mode so that communication will be sent via HTTPS only. HTTPS mode will only be used if WebSockets is not available. WebSockets will be used when available as it will provide better performance. HTTPS mode is required when using SSL VPNs that only proxy HTTPS traffic.

To enable HTTPS Mode, the Plant SCADA Access Anywhere Secure Gateway is required. The Plant SCADA Access Anywhere Server web pages need to be delivered using the web server built into the Plant SCADA Access Anywhere Secure Gateway (files are located under the Webserver/PlantAccessAnywhere folder). Carry out the following steps to enable Plant SCADA Access Anywhere for HTTPS support.

1. Install Plant SCADA Access Anywhere Server on the desired RDP Host.

2. Install the Secure Gateway in a separate machine located in a DMZ. The Secure Gateway needs to be installed on a server that is accessible by the target end-user group(s).

3. To connect to the Plant SCADA Access Anywhere Server using HTTPS - enter the Plant SCADA Access Anywhere URL of the Secure Gateway (the Secure Gateway includes the Plant SCADA Access Anywhere web component)
   https://<securegatewayaddress>/PlantAccessAnywhere/start.html

4. Enter the parameters for the target Plant SCADA Access Anywhere Server in the start.html page.

5. Upon connection, if HTTPS mode is active a ‘-‘ symbol will then be shown as a prefix to the address in the browser tab.
