Maintenance package, basics
Maintenance is a necessity wherever different pieces of equipment are used. For example, drives, valves, motors, where it is necessary to perform maintenance work at specific intervals so as to ensure proper functioning. But prolonging the service life of equipment by means of regular maintenance and cost reduction are also key factors in plant engineering and automation technology.

- PM Agent
  The PM Add-ons product portfolio enhances the base functionality of the WinCC product range. Now this is also supported by WinCC OA.
- Recipes, basics
  Recipe Management Systems are used for managing and storing the set points and commands of automated systems defined by numerous data point elements. Even when simulating or testing an application, a relatively large number of set points or input values need to be sent to the peripheral devices by the control system. In these and other situations such a tool represents a great simplification.
- Scheduler, basics
  The main task of the scheduler is to allow you to create, configure and administrate a number of schedules of either time or event triggered actions.

Configuration in the maintenance package


There are two important panels connected with the maintenance package, the (Panel for operation and the Panel for editing parameters). The functions of these panels are described below.

Panel for operation


The panel for operating the WH/SC can be opened in two ways: By left-clicking on the WH/SC symbol in the plant display. By left-clicking on the device symbol in the plant display for which a WH/SC has been configured and then clicking the "Operating-time" button. (The "Operations" button for an SC) Figure 1. Panel for operation This panel features the following functions: The name of the data point name and the description of the WH/SC is at the top. Displays: Total operating hours, next maintenance/replacement in hours/operations, binary operating information (value of the source data point element), current daily total, value from previous day. At the bottom you can open a trend display by selecting one from the combo box and then pressing the "..." button. You can edit correction values by pressing "...". When you set status bits, the "Status bits:" line displays the respective symbols: Value never set yet. Configured maintenance (Device should be switched off) "Service protocol" button: Opens the service log if maintenance tasks are defined for this device. (otherwise the button is grayed out) "Maintenance" button: Opens a child panel displaying the maintenance tasks created for this WH/SC. After performing a task, you can complete it in WinCC OA by selecting it in the list and then left-clicking "OK". cf. Performing maintenance tasks. (if no maintenance tasks have been defined, this button is grayed out) "Reset PLC counter" button: For a PLC count, this button resets the PLC counter. (otherwise the button is grayed out) "Parameter" button: Opens the configuration panel for the WH/SC. (cf. Panel for editing parameters) "Close" button: Closes the panel for operation.

Panel for editing parameters With the aid of this panel you can edit the WH/SC settings. This panel features the following functions: The name of the data point name and the description of the WH/SC is at the top. The counter source is displayed. Device name (grayed out, cannot be edited) and description are displayed. Display of source data point element (grayed out, cannot be edited). "Services" button: Clicking this button opens another dialog box displaying all configured services for the respective counter. In this window you can create, edit or delete services. (cf.
