7.3.14.3 PDO mapping for logic devices
If the device descriptions for logic devices that are supplied with the »PLC Designer« are used, the
process data are copied to the subordinate logic drive node automatically.
If the process data are still to be linked manually, activate the "direct access to I/O addresses by the
application" option.
In this setting, the prepared function blocks are not usable.
The process data (I/O addresses) must be linked manually.
