• Multiple input connector names can reference the same output connector
name.
• Input and output connectors with unmatched or blank connector names
are not verified.
• The X and Y grid locations are a relative position from the upper-left corner
of the sheet. X is the horizontal position; Y is the vertical position.
These examples show block structure.
L5X block structure
<Block [Block_Attributes]>
<Array Name="name", Operand="operand"/>
</Block>
L5K BLOCK structure
mnemonic_BLOCK (Block_Attributes)
END_mnemonic_BLOCK
Block attributes
L5X Item L5K Item Identifies
Type mnemonic L5X only. The type of Block. Specify the mnemonic name for the block (for example DEDT).
ID ID The element identifier; uniqueness is important for wiring.
Type an unsigned, 32-bit integer value.
X X X-coordinates on internal grid.
Type an unsigned, 32-bit integer value.
Y Y Y-coordinates on internal grid.
Type an unsigned, 32-bit integer value.
Operand Operand (optional) Tag name for the block.
For L5X, this attribute is on the <Array> element.
Name ArrayName (optional) Tag name for array.
For L5X , this attribute is on the <Array> element.
VisiblePins VisiblePins List of the names of all the parameters with pins visible for wiring. The names match the
member names on the block tag.
In an .L5X file, separate pin names with spaces.
In an .L5K file, separate pin names with commas.
AutotuneTag AutotuneTag Tag name for the autotune tag.
HideDesc HideDescription Whether or not to hide the description. Specify true or false.
