This makes it easy to see which input of the safety module has been affected by the problem
and further measures can be taken to remove the fault (check the connecting cables to the
sensors or the connected sensors themselves, etc.).
The following example shows a simplified schematic view:
An emergency stop control device with two N/C contacts is connected to inputs I0 and I1 of
the safety module. The status of the N/C contacts is monitored by the Equivalent safe
functional block at the start of the safety logic. In our example, the functional block reports
an error (ERR output = TRUE, the symbol for the functional block is surrounded by a red
border with the configuration software in online mode).
Therefore, the LEDs for inputs I0 and I1, which are both directly connected to this functional
block, flash on the safety module.

a safe functional block
This function enables hardware errors to be located even without a PC (configuration
software), as the error is also visualized on the hardware thanks to the flashing LED(s) at
the safety module inputs. The project documentation also enables conclusions to be
drawn regarding the relevant safe functional block (i.e., the one reporting the error) using
the flashing module input, without a PC being connected.
