Modul parameters / Custom Parameters of an I/O Module
Modulparameter Dialog
In this dialog the parameters which are given by the device file are shown. Only the column 'value' is
editable.
Index: The Index is a consecutive digit (i), which numbers through all the way the parameters of the
module.
Name: Name of the parameter
Value : Value of the parameter, editable
Initially the default is displayed. Values can be set directly or by means of symbolic names. If the
entries in the configuration file are not set to 'Read Only', they can be edited. To do that click on the
edit field respectively select on of the entries in a scoll list. If the value is a file name, you can open the
dialog 'Oben file' by a doubleclick and browse for another file there.
Default: Default value of the parameters
Min.: minimum value of the parameter (only if no symbolic names are used)
Max.: maximum value of the parameter (only if no symbolic names are used)
A tooltip may give additional information on the currently marked parameter.
Instead of the Modulparameter dialog there might be a customer specific dialog. This is due to the
fact, that such a dialog is linked by an entry (Hook-DLL) at the module definition in the configuration
file.
