8.11 Target Settings - Parameter Manager

The Parameter Manager is a a target specific component of the PLC Designer

programming system and must be activated in the target settings.

The Parameter Manager can be used to make variables of a PLC Designer IEC-program,

constant parameters or specific system parameters accessible to all PLC Designer

compatible systems in a network for the purpose of data exchange, typically via

fieldbus. For this purpose in the editor you can create parameter lists and load down

to and up from the runtime system.

 Note!

Parameter lists also can be created resp. filled with entries via pragmas which are

included in variable declarations.

What are Parameters ?:

In this context parameters are:

• process variables of the PLC Designer IEC project

• process independent parameters

• specific system parameters, predefined by the target system

• functionblock instances or structure variables, arrays

Each parameter is identified by a certain set of attributes like e.g. 'default value',

'access rights', and especially by an unique access key ('Index', 'SubIndex', 'Name'),

which can be addressed for reading or writing data from/to the parameter list. This

data exchange can be done via communication services and it is not necessary to

know any addresses of variables or to provide any extra functions. So the use of the

Parameter Manager functionality it is an alternative to using Network Variables.

What are Parameter Lists?:

Parameter lists are used for organizing the parameters and can be saved with the

project and loaded to the local target system which is controlled by the corresponding

IEC-program. For each type of parameters there is a corresponding type of parameter

list.

Each parameter entry is represented by a line in the parameter list. Each column of the

list is representing one of the parameter attributes. In addition to a certain set of

standard attributes also manufacturer specific attributes might be used for the

description of a parameter in the Parameter Manager.
