Highlights in SDK 4.5, MultiTool version 7.3

Installing CODESYS 3.5 components

Until now, SDK installer has installed device descriptions and libraries to the CODESYS 3.5 repositories. Because of that, all needed CODESYS 3.5 service packs have had to be installed. Otherwise the SDK installer has not been able to install all the devices descriptions and libraries. If new versions of CODESYS were installed after installing the SDK, the SDK had to be reinstalled. Otherwise some of the device descriptions and libraries might not have been correctly installed.

From SDK 4.5 forward, the SDK installer only copies the device descriptions and libraries to the computer. MultiTool handles installing them to the CODESYS 3.5 repositories. MultiTool checks on each startup if new CODESYS versions have been installed. If so, MultiTool reinstalls the device description and libraries to the repositories, to make sure that they are all installed correctly.

Because of this change, new CODESYS 3.5 versions can now be installed after installing the SDK, without the need of reinstalling the SDK.

Saving salve configuration

Saving slave configurations

Configuring slave devices on each startup of the machine may take a long time. This will delay starting to use the machine, and can be annoying to the machine user. We have added a new feature to our CANopen library and MultiTool to enable saving slave parameters after the slave has been configured. In some cases this will significantly speed up starting the machine.
