AbstractModeNode

Short Summary​

This FB is a extention of the AbstractNode, which implements the Hierarchical Composition Pattern, designed to create flexible, extensible, and dynamically configurable node-based systems. This implementation provides a robust framework for creating tree-like structures with mode and signal propagation from the root node to the end nodes.

This node type provides operation modes as methods. The active operation mode will propagated as a mode delegate through the tree.

This node type comes with a cycle manager instance. The cycle manager (THIS^.cycleManager) can be used for mode sequence handling. Attention: The cycle manager is called and updated automatically. Only use the provided properties and methods. Don't call it additionally because this can lead to unexpedted behaviour as it evaluates the edges of control signals!

Parameters

none

Properties​

className​

Type: CNM_AbstractObject.ClassName

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

isEmpty​

Type: BOOL

This property indicates that a node or subunit is empty (no parts are physically present). It is used for the HMI connection.…

Methods​

enterNewMode​

  • Return type: VOID

This method will be called once after a new mode was started. The method is called for exactly one cycle and…

exitCurrentMode​

  • Return type: VOID

This method will be called once after a mdoe was finished (stopped). The method is called for exactly one cycle and…

handleMode​

  • Parameters:
    • execute (BOOL)
    • pause (BOOL)
    • mode (CNM_OpModeHandlingInterfaces.IModeBehaviour)
  • Return type: VOID

This method manages the operation of a mode, handling the execution and pausing states, while coordinating with subnodes and evaluating their states. It ensures the selected mode is active and updates the node's state based on the subnodes and its own operation.…

manageEntryExit​

  • Parameters:
    • execute (BOOL)
    • mode (CNM_OpModeHandlingInterfaces.IModeBehaviour)
  • Return type: VOID

This method monitors the execute flag of the current operation mode.…

monitorAndUpdate​

  • Return type: VOID

This method can be used for cylcically monitoring and update tasks for the node.…

overwriteMode​

This method allows the overwrite of the current mode state with a new mode, provided the current mode state is in IDLE or SUCCESS status,…

resetLocalModes​

This method cleares overwritten modes for a node and all of its subnodes.…

runAutomatic​

This method contains instructions and sequences for the automatic mode. It has to be overwritten for every node.…

runChangeOver​

This method contains instructions and sequences for product type/variant changeover.…

runCleanUp​

This method contains instructions and sequences for the clean up mode.…

runGhostMode​

This method contains instructions and sequences for the ghost mode.…

runReferencing​

This method contains instructions and sequences for the referencing mode.…

runService​

This method contains instructions and sequences for the service mode.…

runSimulated​

This method simulates a node/unit/machine without physical movements, but with all data handling, e.g. handshakes between units, communication with production systems, loading of data.…

Abstract methods​

disable​

This method disables a node. It can take mutliple cycles. It has to be implemented for every node/device.…

enable​

This method enables a node. It can take mutliple cycles. It has to be implemented for every node/device.…

initialize​

This method contains instructions and sequences for the init mode.…

runHoming​

This method contains instructions and sequences for the homing mode. It has to be overwritten for every node.…

runManual​

This method executes manual commands. It has to be overwritten for every node.…

stopImmediate​

This method executes stops all movements of a node. It has to be overwritten for every node.…
