‘Extras’ ‘Connection marker’

Connections can also be represented by a connector (connection marker) instead of a connecting line. Here the output and the associated input have a connector added to them which is given a unique name.

Where a connection already exists between the two elements which should now be represented by connectors, the output of the connecting line is marked and the menu point ‘Extras’ ‘Connection marker’ is selected. The following diagram shows a connection before and after the selection of this menu point.

A unique name is given as standard by the program which begins with M, but which can be changed The connector name is stored as an output parameter, but can be edited both at the input and at the output.

It is important to know that the connector name is associated with a property of the output of a connection and is stored with it.

1. Edit the connector at the output:

If the text in the connector is replaced, the new connector name is adopted by all associated connectors at the inputs. One cannot, however, select a name which already belongs to another connection marker since the uniqueness of the connector name would be violated.

2. Edit the connector at the input:

If the text in a connector is replaced, it will also be replaced in the corresponding connection marker on the other POU. Connections in connector representations can be converted to normal connections in that one marks the output of the connections (Cursor position 4) and again selects the menu point ‘Extras’ ‘Connection marker’.
