1. thanks for letting me know. I will fix this ASAP. In the meantime you can find the pictures in the attachments.
2. Defining your own FBs in 4diac is described in the help under "Step by Step Tutorials / Step 4 - Create your own FBs". The existing ROS ACTION and SERVICE FBs can be used as a template for implementing your own customized FBs.
The difference between CBasicFB and CEventSourceFB is the following:
- CBasicFB is related to the Basic function block which is implemented according to ECCs (Execution Control Charts).
- CEventSourceFB is related to Service Interface Function Blocks (SIFB) which are interacting with the environment (e.g., hardware access (IOs), network access (pub/sub, client/server), ...) and are described by Service Sequence Diagrams instead of ECCs. The ROS FBs are network communication FBs and therefore SIFBs.
