Properties​

className​

Type: CNM_AbstractObject.ClassName

This abstract property returns the class name of the concrete object,…

override​

Type: LREAL

This property returns the effective override for a node, which is the result of the multiplication of global and local override.…

stopRequest​

Type: BOOL

This property represents the stop request signal which either the operator triggers from the HMI or which is set by an error.…

Methods​

assignGlobalReferences​

  • Parameters:
    • data (REFERENCE TO CNM_OpModeHandlingInterfaces.NodeHandlerControlStruct)
  • Return type: VOID

This method is used during the initialization of the nodes to receive the mode data references from the parent node.…

FB_init​

  • Parameters:
    • bInitRetains (BOOL): if TRUE, the retain variables are initialized (warm start / cold start)
    • bInCopyCode (BOOL): if TRUE, the instance afterwards gets moved into the copy code (online change)
    • localOverride (REFERENCE TO LREAL)
  • Return type: BOOL

The constructor FB_init is needed to create an unique hash code.…
