Configuring the logic
The free function blocks are configured at the parameter level. The input of a function block
can be linked to any output by entering the output's Q number in the input's REF parameter.
The outputs' Q numbers can be found in Image 6-6 FBLOCK overview (Page 87).
The REF parameters can be found in Table 6-45 FBLOCK-REF parameters (Page 182).
Example logic
The following figure shows an example logic. In the example logic, the level-controlled
outputs of the digital inputs DI3 and DI2 and a 1 ("high") are linked via the FBLOCK "AND0"
with the FBLOCK "Fault acknowledgement".

Example logic
Factory defaults
The special "emergency power mode" function block is already linked to the level-controlled
output of the digital input DI0 (terminal X5) by virtue of the factory default settings. The Q
number 4 is stored in the REF parameter of the input p20124 for this.
Note
Factory settings of ATD4xxW (firmware version 1.03 or higher)
A logical connection between the "emergency power mode" function block and DI0 (X5) is
not set in the case of ATD4xxW controllers (firmware version 1.03 or higher).
