If you move a normal block to another time level, you must specify
block’s number in this time level.
• If you click on an input pin of a block and this pin is connected to
an output pin, the page that contains the block with this output pin
opens.
• If you click on an output pin of a block, a dialog box opens. This
box displays the user-defined symbolic name of this output pin (if
any) and a list of all blocks that use this output pin.
If you double-click on a block in this list, the page that contains this
block opens.
If you want to define a symbolic name for this output pin, you write
the name to the Symbol field and click the OK button.
An item-specific dialog box opens and you can enter the needed
values to this dialog box.
• If you click on a function block (or on an empty NO block
rectangle), you can either insert a new block or remove or change
the selected block.
If you insert a new block, the last block in the block chain will be
dropped out.
If you remove a block, a new NO block will be added to the end of
the block chain.
Press the F3 key if you want to see the description of the block you
have selected from the block type list of the dialog box (this is not
necessary if the Info window is already on the screen).
• If you click on an input pin of a block, you can either change the
connection of this pin or set its value (if you have just before
clicked on an output pin, this pin is connected to the input pin)
• If you click on the time level box, you can change the time level of
this program.
• If you click on an user constant (in the highest part of the left side),
you can change the value of this constant.
• The lowest part of the left side is used for user-specified (non-AP)
parameters and their user-specified values.
When this AP program is downloaded to the connected drive, the
values of these parameters (if any) are downloaded to the drive,
too.
If no parameters have been specified, you must click on the lowest
(empty) box of the left side in order to insert the first user-specified
parameter and its value. Otherwise you click on an user-specified
parameter to insert a new parameter or to remove or change the
selected parameter.
