
Resource objects (devices tree):
These are device objects, applications, task configurations, recipe managers etc.
and are ONLY managed in the Devices window, i.e. in the "device tree". When
inserting objects in the devices tree, the hardware to be controlled must be
mapped according to certain rules. The scope of objects like e.g. libraries, GVLs etc.
thereby is defined by the hierarchical arrangement of application and device
objects within the tree.
• Code generation by integrated compilers and use of machine code results in short
execution times.
• Data transfer to the controller device: The data transfer between »PLC Designer«
and the device is done via a gateway (component)) and a runtime system.
Complete online functionality for controlling a program on the device is available.
• Predefined feature sets serve to be able to choose between a "standard" user
interface with a reduced selection of features and less complexity and a
"professional" environment supporting all features. When the programming
system is initially started after the first installation on the system, you will be
prompted to choose one of the sets. But also later you still can switch the set and
also a user-defined customization of the currently used feature set is possible. For
the particular differences between the standard and professional version please
see the description of the Feature Options.
3.2 Differences to »PLC Designer« V2.3
Basically: Projects created with »PLC Designer« V2.3 can be opened and edited further
on.
The following extensions and improvements are available with »PLC Designer« V3.x:
Object orientation in programming and project structure
• extensions to function blocks: Properties, Interfaces, Methods, Inheritance, Method
invocation
• extensible functions - not yet implemented
• device bound applications are instances of independent programming objects
New concerning Datatypes
• new type: ANY_TYPE
• new type: UNION
• new type: LTIME
• new type: References
• enumerations: base data type can be specified
• di : DINT := DINT#16#FFFFFFFF; not allowed
