7 Configuring example
7.3 Safety Integrated with SPL
$A_INSEP / On the PLC, the I/O input and output bits must be assigned in SPL interface
$A_OUTSEP PLC DB18.
External PLC inputs
DB18.DBX38.0 ... DB18.DBX41.7 :
DB18.DBX42.0 ... DB18.DBX45.7 :
External PLC outputs
DB18.DBX46.0 ...DB18.DBX49.7 :
DB18.DBX50.0 ...DB18.DBX53.7 :
They are assigned bitwise in the user program.
Configuration example:

$A_INSIP / The same procedure is applied to the internal SPL inputs or outputs:
$A_OUTSIP PLC
Internal SPL inputs
DB18.DBX54.0 ... DB18.DBX57.7 :
DB18.DBX58.0 ... DB18.DBX61.7 :
The SGAs are output signals of the SI function and can be mapped to the DB18
variables $A_INSIP[n]. These can be read in the PLC-SPL and used as inputs
for the logic operations.
Internal SPL outputs
DB18.DBX62.0 ...DB18.DBX65.7 :
DB18.DBX66.0 ...DB18.DBX69.7 :
The SGEs are input signals of the SI function and their values are assigned
from the DB18 variables $A_OUTSIP[n]. These can be written in the PLC-SPL.
