These is a small tutorial example which gives you a good introduction into typical SCIOPTA systems and products.

It would be a good starting point for more complex applications and your real projects.

3.2 Example Description

Figure 3-1: Process-Message Diagram of a Simple Hello World Example

hello display

STRING_MSG_ID

ACK_MSG_ID

prio = 16 prio = 17

Process hello sends four messages (STRING_MSG_ID) containing a character string to process display. For each

transmitted message, process hello waits for an acknowledge message (ACK_MSG_ID) from process display be-

fore the next string message is sent.

After all four messages have b

een sent process hello sleeps for a while and restarts the whole cycle again for ever.

Each message is received, displayed and freed by process display. Process display sends back an acknowledge

message (ACK_MSG_ID) for every received message.
