5 - Editors in CoDeSys
'Insert' 'Parallel Branch (right)'
Symbol:
Shortcut: +
This command inserts a parallel branch in the SFC editor as the right branch of the marked block. For
this the marked block must both begin and end with a step. The new branch is then made up of one
step. To allow jumps to the parallel branches that have been created, these must be provided with a
jump label.
'Insert' 'Parallel Branch (left)'
Symbol:
'Insert' 'Jump'
'This command inserts a parallel branch in the SFC editor as the left branch of the marked block. For
this the marked block must both begin and end with a step. The new branch is then made up of one
step. To allow jumps to the parallel branches that have been created, these must be provided with a
jump label (see 'Extras' 'Add label to parallel branch').
'This command inserts a jump in the SFC editor at the end of the branch, to which the marked block
belongs. For this the branch must be an alternative branch.
The inserted text string 'Step' in the inserted jump can then be selected and replaced by the step
name or the jump label of a parallel branch to be jumped to.
'Insert' 'Transition-Jump'
Symbol:
This command inserts a transition in the SFC editor, followed by a jump at the end of the selected
branch. For this the branch must be a parallel branch.
The inserted text string 'Step' in the inserted jump can then be selected and replaced by the step
name or the jump label of a parallel branch to be jumped to.
'Insert' 'Add Entry-Action'
With this command you can add an entry action to a step. An entry-action is only executed once, right
after the step has become active. The entry-action can be implemented in a language of your choice.
A step with an entry -action is designated by an "E" in the bottom left corner.
'Insert' 'Add Exit-Action'
With this command you can add an exit-action to a step. An exit-action is only executed once, before
the step is deactivated. The exit-action can be implemented in a language of your choice.
A step with an exit-action is designated by an "X" in the lower right corner.
'Extras' 'Paste Parallel Branch (right)'
This command pastes the contents of the clipboard as a right parallel branch of the marked block. For
this the marked block must both begin and end with a step. The contents of the clipboard must,
likewise, be an SFC block that both begins and ends with a step.
'Extras' 'Add label to parallel branch'
In order to provide a newly inserted parallel branch with a jump label, the transition occurring before
the parallel branching must be marked and the command 'Add label to parallel branch' must be
executed. At that point, the parallel branch will be given a standard name consisting of „Parallel" and
an appended serial number, which can be edited according to the rules for identifier names. In the
following example, "Parallel" was replaced by "Par_1_2" and the jump to the transition "End" was
steered to this jump label.
