Function blocks
The »PLC Designer« contains function blocks which enable the PLC program to directly access the
parameters of the Controller and the connected field devices.
Parameters which can be accessed are ...
• device parameters or logbook entries of the Controller;
• device parameters of the field devices (example: Servo Inverter i700).
Memory sizes of the controllers
Operating systems of the Controllers
The operating systems and the PLC applications use the available RAM memory area of the
Controller together (see above).
