4.5.7.2 IFdtFunctionBlockData::SelectFBInstance()
| This method can be called in the states: |      |
|
HRESULT SelectFBInstance ( [in] BSTR systemTag, [out, retval] VARIANT_BOOL* result ); |
Description:
| Before a DTM of a failsafe device can verify the consistency of the device parameters, the user has to assign the Proxy FB in the host (bus master) to the DTM which contains the parameters of the failsafe device. |
Parameters:
| systemTag | Identifier of the device instance |
Return Value:
| result | TRUE Function block associated. FALSE No function block associated |
Behavior:
| Opens a browser which offers all available Proxy FBs that contain individual device parameter of devices. The user has to select the Proxy FB of the corresponding failsafe device for the DTM. The bus-master-DTM stores the assignment of the Proxy FB to the calling DTM-Instance. The mechanism of assigning a DTM to a failsafe device is defined in more detail in section "4.5.3 F Parameter Assignment Paths" of the document "PROFIBUS Profile for Safety Technology, Version 1.20, 23-Oct-2002" . If a Communication-DTM is not able to support failsafe functionality, it will return a "false" success |
