System structure

Topology of semi?automatic STS crane

Application part

The individual products process input parameters and output results or setpoints. The technological procedure, interlocks, and crane?specific conversions etc. must be performed and taken into consideration in the crane application.

• Coordinate transformation
• Setpoint calculation for motion control
• Crane controller signaling system
• Control of TLS closed?loop control (skew control)
• Evaluation of the laser for height profile acquisition (bay scanner)
• Structure of procedure and control of axes
• Safety functions

Details of the individual SIMOCRANE products as well as further configuration options can be found in the Sections:

• SIMOCRANE Standard Technology
• SIMOCRANE Advanced Technology
• SIMOCRANE CMS (Crane Management System)

Software structure and function modules

Function blocks of the application example for a semi?automatic STS crane

The figure shows where which software modules execute or are implemented. The symbols with a green background indicate those function modules that are required especially for the application described here.

The "sensor controller" includes all function modules for determining the positions of the containers or vehicles. The sway control functions of SIMOCRANE SC execute on SIMOTION D as well as the motion control of SIMOCRANE Basic Technology. The application?specific parts, such as traffic light and cylinder controllers are implemented on the crane controller (PLC).

Data is exchanged between the 3 units sensor controller, SIMOTION D and PLC over defined interfaces which is symbolized in the figure by "COMMAND" and "STATUS".
