The InTouch
Machine Edition Web Thin Client is a powerful tool
for getting access to HMI applications designed in InTouch Machine
Edition remotely. The web thin client is especially
valuable to plant managers who wish to view a process while in an office or
using a smartphone or PDA. OEMs may also benefit from providing a web thin
client for use in viewing the HMIs used in equipment.
The web thin client will
run on a variety of devices. Any windows desktop powered with Internet Explorer
(including IE10) will be able to access the web thin client. In addition,
embedded operating systems such as Embedded Standard or Compact will display
the thin client.
The web
thin client provides operators and plant managers with a full graphical
representation of screens, which correspond exactly to those available on the
host machine. In addition, because the web thin client requires far less
computing power to use, cost can be saved in hardware. Another added benefit is
improved downtime. If the hardware supporting the web thin client goes down,
there is nothing to reinstall, so it is easy to swap one panel for a new one
and bring a machine back online instantly. To view a demo of the web thin client, please follow the instructions
below.
- You will be prompted:
- User Name: Guest Password:
- [no password required]
- Press OK to access the demo application
Important note:
It requires the
installation of a plug-in (ISSymbol ActiveX control), which should be done
automatically when the user attempts to visualize the screens for the first
time from the Web Thin Client station (as long as the security settings of IE
allows to automatic installation of plug-ins). Ideal for multi-purpose stations
(e.g.: Manager’s computer). If you have any problem viewing the demo, please check the Troubleshooting
section below.
This
section describes some example architectures applied for web-based solutions
and provides information on how to configure the project for each architecture.
This section does not describe all possible architectures, but it provides the basic
concepts necessary to design different scenarios based on the basic
architectures illustrated below.
Troubleshooting
If you have any problem viewing the
demo, please check the following items:
Make sure that your Web Browser is Internet
Explorer version 10 or higher.
The first time that you attempt to
connect to the Server, your browser will download the ISSymbol control from Wonderware’s
web site. It may take a few seconds or even minutes (depending on the speed of
your internet connection). After downloading this control, you will be prompted
with a dialog asking if you want to install ISSymbol in your computer. Just
press the Yes button and you will be connected to the demo application.
This procedure is only executed the first time you attempt to view the demo
from your computer.
Make sure that the following
settings from the Security system from Internet Explorer are set as Enable
or Prompt (Tools > Internet Options > Security (Custom Level):
Download signed ActiveX controls
Run ActiveX controls and plug-ins.
Script ActiveX controls marked safe
for scripting.
Note: Due to new Windows security requirements, some
Windows 8 machines may not allow updating of the ISSymbol.ocx in Internet
Explorer. The symptoms of this issue occurring is the Live demo web page
will remain blank after following the instructions shown above.
If this happens, manually install
the ISSymbol.ocx. Just run the Thin Client Installation (after you download and install the Wonderware
InTouch Machine Edition from its web page you can find the Thin Client Setup here: C:\Program Files\Wonderware\InTouch Machine
Edition v8.0\Redist\WebAddOn\ThinClient\ThinClientSetup.exe
As an alternative, Internet Explorer
can be Run As Administrator before navigating to the Live Demo. Once the ISSymbol.ocx is installed,
if you do not immediately get the demo logon screen, close I.E. and restart it
normally.
If the problem persists, please Contact Us.
