• Receive messages without corresponding send messages form the signal sinks in INTECRIO, send messages without corresponding receive messages form the signal sources in INTECRIO.
If desired, you can make connected messages appear as signal sinks and sources, too.
• When your project contains unresolved messages (imported messages without corresponding export), code generation for INTECRIO produces an error message.
You can resolve the messages automatically, or cancel code generation and resolve the messages manually.
• Using global variables and parameters is possible, but strongly discouraged.
• In the project options, you must select an appropriate target so that code generation for INTECRIO is available.
Contents of the Description File
The interface description file that is automatically created during the code generation, the SCOOP-IX file, contains the following information if they were specified in ASCET:
• Signal sources (send messages) and signal sinks (receive messages)
– Name
– Physical value range
– Implementation data type and value range (can also be calculated using the physical value range and the quantization formula)
– Quantization formula
• Parameters and variables (no distinction is made between one, two and three-dimensional quantities)
– Name
– Physical value range
– implementation data type and quantization
– Hierarchical information, i.e. the exact location of the quantity in the model
• Activation interfaces (processes)
– Timing information for cyclical processes
The Hardware Configurator
During the development of a control algorithm, the actual controlled system must be addressed at some time so that realistic results can be achieved. The controlled system (or the technical process) appears to the rapid prototyping system as a set of sensors and actuators with which the system can be connected using a series of appropriate peripheral devices.
These peripheral devices must be configured so that they fit the actual technical process that must be modeled. For example, for A/D converters it is possible to configure the input range, scanning/keeping, etc. In addition, the signal
