Shared Device

The SharedDevice feature is available at TwinCAT 2 Build  22.50 or TwinCAT 3 Build 4019.

The dialog appears if the device support "shared device". The information comes from the GSDML.

Here it is possible to give the controller access to the individual submodules or to withdraw them. By default, the controller has access to all submodules. If shared input is supported, it is switched off.

The text messages of SharedInput have the following meaning:

• "not supported"         -   SharedInput is not supported from the device (information from the GSDML)
• "has output data"      -   the submodule has outputs - the activation of SharedInput ist not possible
• "no Input data"          -    the submodule has no inputs (also no outputs)
• "no access"               -    the access is locked
• "true" bzw. "false"     -    current setting for SharedInput

The settings can be changed by double-clicking on the individual submodules. If the access to a port or interface submodule is changed, it will be changed for all ports or interfaces.
