UC_SYSTEM_SETTINGS - Systemwide Settings

This predefined system Variable (VARA) object is supplied in Client 0 and contains settings that apply throughout an entire Automation Engine system. This variable object can only be changed in Client 0.

The Automation Engine monitors all the values that are included in this variable. As a system administrator, you receive a message every time a user attempts to store an invalid value in this variable. This message is also written to the log file of the Automation Engine. If an invalid value is used, the system uses the default value instead. If the invalid value is a range and the specified maximum value is exceeded, the system uses the maximum value. The minimum value is used if a value that lies below the minimum value is found. The variable's contents remain unchanged.
