In order to increase the visibility of energy (temperature, pressure, water use, etc.) use in the production industry, it is the process of collecting and analyzing data instantly from certain points of the hierarchy (plant, work center, equipment, machine, etc.) and then periodically reporting it at the level of production event, tariff, and shift.
The benefits of energy monitoring are:
- Unnecessary consumption of resources is prevented.
- Helps to optimize energy use.
- Provides the display of real-time and historical data.
- Shortens the reporting process.
- Has a user-friendly interface.
SAP MII Energy Monitoring and Analysis UIs
Follows the SAP MII Menu > Energy Monitoring and Analysis > Energy Configurations path to Energy Monitoring and Analysis screen.
Configuration processes consist of four parts:
- Production Event Templates
- Production Event Maintenance
- Shift Pattern Maintenance
- Tariff Maintenance
Production Event Templates
The use of Production Event Templates is collecting energy data at the production event level.
One of the ME, OEE, and Third-Party options must be chosen in the Template Type field. Next, a meaningful template name must be written in the Template Name field. Lastly, tables that will be used for collecting data must be chosen in the Source Table field. If the Relevant For Analysis box is selected, that means analysis will be related to the selection of this field. For the weighting of data collected, Weighting Factor must be selected for the preferred field. Also, grouping with the Property feature is available.
P.S. If ZTable is in preferred use, the Third Party option must be selected in the Template Type field, considering that Third-Party selection only allows one table entry in the Source Table field.
Production Event Maintenance
Production Event Maintenance collects and reports production-related energy consumption data at the production event level.
After creating the Production Event Template, create an event with the Production Event Maintenance section. Entering a name to Production Event Name field, select any template with Production Event Template field and select source database with Source Data Server field, and then save it. After these processes, the created table includes selected fields in the Database. The created table is shown in Fig. 3.1
P.S. If any production or process order status is active, data will be recorded in the database.
Follows the MII Menu > System Management Scheduler path to creating a new scheduler for transferring data to created table. When creating a new scheduler, select Production Event in the Scheduler Type field and enter a name for the Name field and then save it. (Fig. 3.2)
After being created a new scheduler, the Enabled checkbox should be marked in the Production Event Scheduler tab. Otherwise, Scheduler will not be active. Should be entered the name of the table to which the data will be transferred in the Production Event Table field, and also select date to start scheduler in the Start Date field. Required run time specification (second, hour, day, month) for Scheduler must be entered in the Pattern field. Lastly, the Scheduler must be activated with the Run Job button. (Fig. 3.3)
Shift Pattern Maintenance
Shift Pattern Maintenance collects and reports production-related energy consumption data at shift level.
Follows the MII Menu > Energy Monitoring and Analysis > Energy Configurations > Shift Pattern Maintenance path.
A new Shift Pattern can be obtained by Create button. A meaningful template name must be written in the Template Name field to continue. In the Shift Schedule tab, the Schedule must be entered to the Schedule field from MII Menu > Data Services > Time Periods Schedules, and then, the preferred date interval must be entered. (Fig. 4)
Follows the MII Menu > Data Services > Time Periods Schedules path to create schedule. After that, the time interval created from MII Menu > Data Services > Time Periods must be assigned to the Schedule. (Fig. 4.1)
Tariff Maintenance is the collection of energy data used in the field of production on a tariff level and reporting on a cost level.
Follows the MII Menu > Energy Monitoring and Analysis > Energy Configurations > Tariff Maintenance path to reach.
On the Tariffs tab, a meaningful name is entered in the Name field. A category is selected for the Category field that was created on the MII Menu > Catalog Services > Category section. Unit of Measure is the determination of the ratio of energy units consumed in a specified price unit.
Unit of Measure = (Unit of Price / Unit of Energy)
e.g. $ / kWh
The valid date interval that you want to run is selected from the Validity Periods tab. In the Rates tab, since there may be different pricing tariffs at certain times of the day, the desired time is selected and the desired rate is entered in this time interval. Electricity charges may be high or low from time to time. Rate must be entered according to these time intervals.
For example, Rate 0.5 was entered because electricity charging may be low between 02:00 a.m – 05:00 a.m. A new tariff group is created with the Create button on the Tariff Groups tab. The Name and Description field is entered with a meaningful name.
A category created on the MII Menu > Catalog Services > Category screen is selected for the Category field, and finally, the Tariff field is selected as the tariff that was created on the Tariffs tab. (Fig. 5.1)
Configuration of Plant Information Catalog
The Plant Information Catalog means the logical hierarchy for a shop floor. It determines in which hierarchical structure it will collect data at the shop-floor level for SAP MII. Plant Information Catalog objects can be mapped to PP and PM objects from ERP.
To use the Plant Information Catalog, it must be installed on SAP MII NetWeaver. First, the UserName, Password, Language, ServerName, and PortNumber fields are entered according to the ERP information for the Plant Information Catalog Connection via the http://IP:PORT/nwa > Configuration > Application Resources, and ERP-PIC connection is made on the SAP MII. (Fig. 6)
After PIC connection is performed, ERP Sources are selected via Plant Information Sources by following SAP MII Menu > Catalog Services > Plant Information Maintenance path to gain access to PM and PP hierarchies. (Fig. 6.1)
Once hierarchies are accessed, an existing hierarchy can be transferred or a new hierarchy can be created with the New button. After you determine at which hierarchy level the data is collected, the properties of the SAP_Tariff and SAP_ShiftPattern are added and saved on the Property Set tab. (Fig 6.2)
Shift Pattern Maintenance and Tariff Maintenance name fields at the Energy Configurations section must be assigned to SAP_ShiftPattern and SAP_Tariff Property Sets’ Property Value field placed on the Properties tab at the level of Plant. (Fig. 6.3)
Self Service Composition Environment
Report with SSCE(Self Service Composition Environment) section. (Fig. 7)
P.S. Reports can be edited according to business needs.
