Real-Time Windows Target 2.0 Release Notes (Real-Time Windows Target Release Notes)

Real-Time Windows Target Release Notes

Upgrading from an Earlier Release

This section describes the upgrade issues involved in moving from the Real-Time Windows Target 1.0 and 1.5 to the Real-Time Windows Target 2.0.

Reinstall the Real-Time Windows Kernel

When upgrading from an earlier release, first uninstall the Real-Time Windows Target kernel. In the MATLAB window, type

```
rtwintgt -uninstall
```

After you install MATLAB R12 products, including the Real-Time Windows Target 2.0, install the new Real-Time Windows Target kernel. In the MATLAB window, type

```
rtwintgt -install
```

Depending on which version of Windows you are using on your PC, you may need to reboot your PC before using the Real-Time Windows Target. If a reboot is required, a message appears indicating a reboot is needed.

Enter New External Mode Interface Filename

The name of the external mode interface file was change from win_tgt to rtwinext. If you create a new Simulink model, the new filename is entered correctly. If you have Simulink models where you used Real-Time Windows Target 1.0 or 1.5, you need to change the filename using the following procedure:

In the Simulink window, and from the Tools menu, click External mode control panel.
On the External Mode Control Panel dialog box, click the Target interface button.
In the External Target Interface dialog box, and in the MEX-file for external mode box, enter

```
rtwinext
```

Click Ok.

Remove I/O Adapter Blocks from Your Simulink Model

I/O Adapter blocks have been eliminated from the Real-Time Windows Target 2.0. You need to remove all I/O Adapter blocks from your Simulink model. Before removing these blocks, we recommend that you record board and connectivity information.

You now enter specific board information in the individual driver blocks. However, you only have to do this once. After entering information in the first block, you can select your board from a pull-down list in the following blocks.

Replace I/O Driver Blocks in Your Simulink Model

the Real-Time Windows Target 1.0 and 1.5 had only two driver blocks - RT Input and RT Output. In the Real-Time Windows Target 2.0, the drivers are now divided into Analog Input (A/D), Analog Output (D/A), Digital Input, Digital Output, and others.

You need to remove all the Real-Time Windows Target 1.0 and 1.5 blocks from your Simulink model and replace them with the new Version 2.0 blocks. Remember to replace RT Input with the appropriate Analog Input and Digital Input blocks. And similarity, you must replace RT Output with Analog Output and Digital Output blocks. For example, if you had a block with both analog input and digital input, you must replace this block by adding two new blocks.
