The T5 Registry enables you to design and monitor remotely a hierarchical registry of parameters. Parameters can be set apart from the Workbench Studio, and can also be read or written from the IEC program.

The following functions are available:

RegParGet Get the current value of a parameter.
RegParPut Change the value of a parameter.

Parameter pathnames

Any parameter is specified by a full qualified pathname that gives its exact location in the registry. The / separator is used to separate folders in the pathname. For a registry defined as:

(Root)
   - Folder1
      - Folder2
         - MyParam

The pathname of the parameter will be:

    /Folder1/Folder2/MyParam

attentionAttention
  • T5 Registry may be not available on some targets. Please refer to OEM instructions for further details about available features.
  • All parameter pathnames are case sensitive.

RegParGet: get the current value of a parameter

Q := RegParGet (PATH, DEF);

PATH : STRING specifies the full pathname of the parameter in the registry.
DEF : ANY     default value to be returned if the parameter does not exist.
Q : ANY       current value of the parameter.

attentionAttention

The DEF input defines the actual type for ANY pins. If you specify a constant expression, it must be fully type-qualified according to the wished returned value. Example for getting a parameter as an INT:

    intVariable := RegParGet ('\MyParam', INT#0);

All pathnames are case sensitive.

RegParPut: change the value of a parameter

OK := RegParPut (PATH, IN);

PATH : STRING specifies the full pathname of the parameter in the registry.
IN : ANY      new value for the parameter.
OK : BOOL     TRUE if successful.

The function will returned FALSE in the following cases:

  • The specified pathname is not found in the registry.
  • The registry is currently being saved and cannot be changed.
