Memory Mapped File

The “Memory Mapped File” hardware is used, for example, to simulate an interface via the main memory. Each DataBlock is stored in a separate memory mapped file. To simulate the data exchange, the same configuration can be used on a computer, only with reversed in/out data.

1. Type: Memory mapped file (RAM)

2. ID: ID assigned

3. name suffix: Name control

4. Create: Press button to generate object

5. DisplayName: Name control

6. +: Adding data areas to be used for communication

1. DataBlockID: ID for this data block.

2. Length: Length of the data area

3. Name: Name of the data area

4. Create: Specifies whether to create the memory-mapped file if it does not exist.

5. MappingObjectName: System global name of the memory mapped file.

6. SimTimeRead/Write: Simulation time in [ms] for read or write accesses.

7. Timeout: Maximum waiting time in [ms] for access to the memory mapped file. (The accesses to the memory are protected from simultaneous access by the GInOut via a system global mutex per memory mapped file).
