Concepts and Base Components

58 DMS 4.1 EN 03/2011 TD29 

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
