Figure 106: Simplified CBB initiation diagram
INIT_1...6 =
CBB1...CBB2 =
The operation of a CBB consists of two parts: initiation and execution. In the initiation
part, the status of the initiation lines is compared to the CBB settings. In order to allow
the initiation at any of the initiation line activation, the corresponding switch in the
Init signals CBB_ parameter must be set to TRUE. In order to block the initiation,
the corresponding switch in the Blk signals CBB_ parameter must be set to TRUE.
If any of the initiation lines set with the Init signals CBB_ parameter is active and no
initiation line causes blocking, the CBB requests for execution.
