Interbus Error (ILIB0006): The CR ... is missing from the Interbus device configuration.
In the INTERBUS configuration of your project, a Communication References (CRs) of a PCP device is missing or '0'.
The CR must be greater than 2, unique for each INTERBUS module and all CRs must be assigned in ascending order and without gaps.
Background information: Peripherals Communication Protocol (PCP) and Communication Reference (CR)
The Peripherals Communication Protocol (PCP) takes over the transmission of parameterization data via the INTERBUS parameter channel. Parameterization data is acyclic data that is only transmitted when required.
The logical connections configured in a communication relationship list ensure a smooth data exchange between two communication partners. The connection parameters (context conditions) of both communication partners are checked verified before an information exchange. This is done during a connection setup.
Each permitted communication relationship contains a number, the communication reference number (CR). This way, each communication relationship is uniquely identified so that the individual devices can be distinguished.
The INTERBUS master numbers the devices automatically when the INTERBUS system is initialized. It assigns the numbers starting from 2 in the order of the physical bus structure.
The CR must therefore be unique for each INTERBUS module and all CRs must be assigned without gaps.
Remedy
- Double-click the error message to open the 'Device List' of the INTERBUS master.
The affected table rows are marked red.
- Specify unique CRs in an ascending order and without gaps. The first CR value must be '2'.
