Requirements and installation

Requirements

Windows terminal server
Terminal client software

Installation

In order to run WinCC OA on a terminal client perform the following steps:

Install terminal client software
Install WinCC OA on the terminal server and start the project on the terminal server.
Start the client session
Start a WinCC OA VISION with a desired panel. Alternatively you can define the appropriate command (for opening a panel) in the start options of the terminal server client.

Client software installation:

On the client computer choose the setup.exe from the Net\Win32 directory via Add/Remove Programs wizard.
Install the setup.exeby clicking on theNextbutton in the Add/Remove Programs wizard.

WinCC OA installation

Note the following points:

Install WinCC OA only through the Add/Remove Programs Wizard (System management - Add/Remove Programs - Add new programs).(Not direct from the DVD).
Start the setup.exe. See chapter Installation under Windows or Installation under Linux for information on how to install WinCC OA.

Start the project on the server.

Start a client session:

Click on Start -> Programs -> Accessories->Communications -> Remote desktop on the client computer.
Select the proper terminal server. Here you can select if you want specify the server name or the IP address of the server. You can start the session immediately or set different options like user, display (resolution and colors) etc. via the tabs first. The most important tab is "Programs" which allows to start WinCC OA immediately or shows the desktop of the server. WinCC OA is started as follows on the client computer:
```
WCCOAUI -num 2 -extend -p basisPanel.pnl
```
Note that if you only open a VISION (without opening a specific panel) the VISION is opened in default size and the module size is adapted when a panel is loaded.

It is also possible to pass dollar parameters when opening a panel. Proceed as follows:
```
WCCOAUI -num 2 -extend -p basisPanel.pnl,"$dp:test"
```
Under linux you have to use '$dp:test' instead of "$dp:test".
Connect (via the "Connect" button) and the session is started.
Log in.

If you did not start the VISION immediately there are two possibilities to do it: either via the console or via the command line. The command line start looks as follows:

WCCOAUI -num 2 -p vision\panels\basisPanel.pnl

Note that if you want to close the VISION you have to do it explicit from the client computer before you close the terminal server client session. If you ONLY close the terminal server client session the VISION still runs on the server and so reserves the UI number further. You can alternatively set the terminal service so that a session, which was not closed properly, is closed after x minutes (set time) automatically on the server. Also all programs, which were opened during the session, are closed.

Note that the default session setting for the display is 256 colors. Because of this setting WinCC OA tries to communicate directly with the display in order to set blinking colors (e.g. colors for the alert screen). In order to avoid erroneous presentation of blinking colors the following config entry has to be defined in the config file of the project.

[ui]
blinkAreaSize = 0

Note that the environment variables PVSS_II and PVSS_II_HOME have to be set correctly if you start a VISION as a command or call option via the terminal server client.
