FBD/LD Parser Error (FBDP0002): Invalid connector name '...'

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 invalid identifier is used for a connector. The respective object appears with a red background in the graphical worksheet.

According to the IEC 61131 standard, naming conventions must be observed to ensure that each identifier can be resolved. Double-click the connector name and correct it. Keep in mind that at least two connectors belong together when renaming the connector.

Further Info For information on the naming conventions for identifiers please refer to the respective topics in the chapter "IEC 61131 Programming ‣ Variable/Port Properties ×‣ Extended Identifiers as IEC 61131-3 Variable Names ×".
