1System Function The Graphics System • • •

It displays static and operator-controllable picture elements, such as texts, graphics or buttons It updates dynamic picture elements, e.g. modifies the length of a bar graph in relation to a process value It reacts to operator input, e.g. the clicking of a button, or the entry of a text in an input field

Archiving System • • • •

It writes the process values that have to be archived to the process value archive in runtime It reads the archived process values from the process value archive when needed It outputs the time course of process values in a picture It prints out process values from the archive database as a report

Alarm Logging System • •

It provides the operator with information relating to the operating status and the fault status of the process. It informs the operator of critical situations at a very early stage and help to eliminate idle time.

The system runtime interfaces are shown as follows.

5 Archiving Process Values WinCC allows you to save the process values in the process value archive. The archive can, for example, be used at a later point in time to display and evaluate the temporal development of the process values. Step1: Start Tag Logging via the pop-up menu in WinCC Explorer. As with WinCC Explorer, Tag Logging also has its own navigation and data window.

Step2: The Archive Wizard can be accessed via the pop-up menu for the entry "Archive" in the Tag Logging navigation window. The Archive Wizard will guide you through the required steps.

24/45

Step3: Creating a new Archive Tag

Step4: Configure the new archive tag.

Process value archiving is controlled by cycles and events. The acquisition and archiving cycles enable continuous acquisition and archiving of process values. Furthermore, process value archiving may also be triggered or ended by events. 25/45

6 Setting up an alarm system The message system processes results from functions which monitor actions in the process, on the automation level and in the WinCC System. The message system indicates alarm events recorded both visually and acoustically and archives them electronically and on paper. Freely selectable access to the messages and supplementary information on individual messages ensure that faults are localized and cleared quickly.

6.1 The "Flashing" Property The attribute "Flashing" shows whether in Runtime the value of the analog display appears flashing or not. Step1: Set up Flashing Flags。 Create flashing flags (Type: Boolean) both in PLC programs and in WinCC. When the process value reaches alarming point, the corresponding flashing flag is set to “True” (1) ;when the value returns to normal range, the flag is set to “False” (0).

Step2: Configure the "Flashing Text Active" attribute Open the “I/O Field properties” dialog box. Dynamic the “Flashing Text Active” attribute with the corresponding flashing flag.
