Supports filter operations on variables of the default interface ST_StandardItf.
The IF_StandardFilter interface specifies three switches that refer to either a group of variables or to individual variables from the ST_StandardItf structure.
oActivity switch:
Groups the variables i_xEnable, q_xActive and q_xReady from ST_StandardItf to a filter unit. If the xEnableActivity property of IF_StandardFilter is set to FALSE, these three variables are no longer enabled.
oCommands switch:
Defines iq_diCMD from ST_StandardItf as filter variable If the xEnableCommands property of IF_StandardFilter is set to FALSE, this variable is no longer enabled.
oExceptions switch:
Defines i_xDiagQuit from ST_StandardItf as filter variable If the xEnableExceptions property of IF_StandardFilter is set to FALSE, this variable is no longer enabled.
Filtering, enabling or not enabling variables has a specific meaning that depends on the intended use. In the case of the FB_ModuleLogger, for instance, change tracking and logging are enabled or disabled for the variable group or an individual variable.
