FUNCTION_BLOCK TEST_ADP

FUNCTION_BLOCK TEST_ADP_SKT

This composite function block type is an acceptor for an adapter connection of type `TEST_ADP`, that is, it contains a socket of type `TEST_ADP`. It contains GUI (graphic user interface) elements that enable it to function as a client for the testing of the adapter connection. Additional event and data inputs (`REQ_EVT WITH QI`) and outputs (`CNF_EVT WITH QO`) are provided to illustrate a separate event/data "pass-through" functionality, independent of the plug interface. See the `TEST_ADP_SYS` configuration for an example of the use of an instance of this type. An instance of this type can be launched in a test window with the Run button of the FBDK, with the results shown below.
1. The initial situation.	2. The INIT event creates the GUI elements.	3. Entering data and clicking REQ has no effect, since there is no socket to receive this event and data.	4. Changing the state of QI and clicking REQ_EVT passes the value through to QO, independent of the plug interface.
