If you want both function blocks to receive the same value for a
drive parameter, you should link the first function block’s input node
to the drive parameter. You should link all subsequent inputs using
this drive parameter should be linked to the first function block node
that is linked to the drive parameter.
In this second example, you want the MULTIPLY function block to
receive the same value from the drive parameter as the LIMIT
function block. Here, you would link the input to the MULTIPLY
function block to the input to the LIMIT function block instead of
linking the MULTIPLY function block to the drive parameter itself.

Refer to Chapter 3 for additional information about links and
performance.
Deleting Events from the Execution List
If you delete an event from an execution list, you need to remove all
links that reference the block that is being deleted. You need to do
this because the link information is stored with the function block
that receives the information.
Referring to the second example, if you delete the LIMIT function
block, you need to remove the link that is stored with the MULTIPLY
function block and re-establish the input to the MULTIPLY function.
If you do not remove the link, you will receive an error when you
download the execution list if you are using DriveTools, or the drive
will generate a fault if you are using a PLC.
