FUNCTION_BLOCK TEST_ADP_PLG
| This
composite function block type is a provider for an adapter
connection of type TEST_ADP, that
is, it contains a plug of type TEST_ADP. It contains
GUI (graphic user interface) elements that enable it to function as a
server 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. |

Changing the state of QI and clicking REQ_EVT passes the value through to QO, independent of the plug interface. |
