7.6.2 Function blocks
Function blocks
T
he logic is programmed using function blocks. Function blocks contain inputs and
outputs. The status of the outputs depends on the status of the inputs and the logic of
the function block. Some function blocks can also be parameterized.
The logic programming results from the combination of various function blocks which
are connected to one another and to the inputs and outputs of the safety controller.
Complementary information
•
Y
ou can also activate additional inputs with certain function blocks.
•
You can also activate additional status and diagnostic outputs with certain func‐
tion blocks.
•
Function blocks will be shown in red as long as all inputs have not been con‐
nected.
•
Each function block has a function block index. The function block index shows the
execution sequence.
