Attribute: pin_presentation_order_inputs, pin_presentation_order_outputs

Important

This pragma is not evaluated when {attribute 'pingroup' := '<Group_Name>'} pragma is used.

The pragmas are evaluated in the CFC, FBD, and LD graphical editors, causing the order of inputs/outputs of the affected function block to be displayed as specified. You program the order by assigning the names of the inputs/outputs to the attribute in the desired order.

Syntax:

{attribute 'pin_presentation_order_inputs' := ' <first input name> ', ' <next input names> '}
{attribute 'pin_presentation_order_outputs' := ' <first output name> ', ' <next output names> '}

`' <first input name> ', ' <next input names> '`	Comma-separated names of inputs in the desired order
`' <first output name> ', ' <next output names> '`	Comma-separated names of outputs in the desired order
`*`	Placeholder for all unspecified names If the placeholder is missing, then the missing inputs/outputs are appended at the end.
Insert location	Top line in the declaration part of a function block

Example 287. Example

{attribute 'pin_presentation_order_inputs' := 'input_2,*,input_1'}
{attribute 'pin_presentation_order_outputs' := 'output_2, output_1'}

In the representation of function module instance pouBase_A, the pragmas result in the following arrangement of input and output pins:
