SYSTEM TEST_ARRAY_IO
| This system configuration provides a means for testing the operation of coupled instances of the IN_ARRAY and OUT_ARRAY function block types. Operation of this test configuration is illustrated below. | |
| The initial values before transferring any data. |  |
| The results after pressing the Enter key in the top window. The array is filled out with the default initial value. |  |
| The results after Entering a full array of data. |  |
The results after
Entering an extra array element. This is detected as an error
by the IN_ARRAY element, but the data up to the point of
error is passed on and accepted by the OUT_ARRAY element
because its QI input is tied to 1(TRUE).
If the
QI input of
the OUT_ARRAY had been tied to the QO output
of the IN_ARRAY element, the data would not have been
accepted for display. |
 |
| The results after Entering fewer than N
elements.
Note that the remaining elements
are unaffected.
