Measuring Points and Counters (CS-IB-MC / PM-EQM-SF-MPC) 

Purpose

You use this component in Plant Maintenance (PM) or Customer Service (CS) to enter measurement and counter readings for technical objects. This can be of use in the following situations:

·        You want to document the condition of a technical object at a particular point in time.

Documenting the condition of a particular object is of great importance in cases where detailed records regarding the correct condition have to be kept for legal reasons. This could involve critical values recorded for environmental protection purposes, hazardous working areas that are monitored for health and safety reasons, the condition of equipment in hospitals (intensive care units), as well as measurements of emissions and pollution for objects of all types.

·        You want to perform counter-based maintenance.

Condition and counter-based maintenance tasks are forms of preventive maintenance. Generally, these tasks should reduce the number of breakdowns for your objects.

In the case of counter-based maintenance, maintenance activities are always performed when the counter of the technical object has reached a particular counter reading, for example, every 100 operating hours.

·        You want to perform condition-based maintenance.

In the case of condition-based maintenance, maintenance activities are always performed when the measuring point of a technical object has reached a particular state, for example, every time a brake pad has been worn away to the minimum thickness permitted.

Integration

This component is composed as follows:

·        You enter data manually into the SAP System using the SAP user interface.

·        You use the Internet Application Component  (IAC) to enter data in an entry screen in the browser and transfer this data to the SAP System using the Internet.

·        You can enter data using a barcode reader and transfer it to the SAP System using the PM-PCS interface.

The PM-PCS Interface is an interface between the SAP System and external systems, such as a Process Control System (PCS).

·        You can enter data using a laptop and transfer it to the SAP System using the PM-PCS Interface.

·        Data from a process control system is data that arises during the monitoring, control, regulation, and optimization of a technical process. You can transfer this data to the SAP System using the PM-PCS Interface.

When doing this, you can use a SCADA System (Supervisory Control and Data Acquisition System) which filters the data from the process control system and only transfers to the SAP System the data that is actually relevant.

·        You can use the customer exit to automate your business processes.
