FBD/LD Parser Error (FBDP0008): A connector cannot connect to itself.
In FBD/LD, connectors can be used instead of lines. In order to substitute a line, one or more input connectors (which is/are read within the graphical code network) and exactly one output connector (which is written within the graphical code network) with the same name are required. Connectors are only valid within the same code worksheet. For "crossing" worksheets, jumps can be used.
In a worksheet, an output connector connects itself. This is not allowed as it would result in a recursive behavior. Recursions are also invalid if the involved connectors are cascaded.
