Managing PEM Attributes

The Production Events Module (PEM) functionality within the OCO lets you monitor, report, and analyze production history and genealogy for lots, batches, and serial numbers without having to define the full MES model.

Note: PEM attributes should not be used in conjunction with an MES process model.

The PEM attributes and commands are on the PEM Attributes tab in the Object Editor. For this tab to appear in the Object Editor, the Enable PEM Attributes option on the General tab must be selected. When the Enable PEM Attributes option is selected, the Entity Can Run Jobs option on the General tab is automatically selected. When Entity Model Builder is run, the entity will have the Can Log Data capability option enabled.

The PEM functionality in the OCO delivers the information defined in the ISA-95 Production Performance category. This category includes the following production classes of information:

• Material Produced Actual

• Material Consumed Actual

• Material Consumable Actual

• Personnel Actual

• Equipment Actual

• Production Data

  Note: The PEM instances are not intended to be ISA-95 compliant, but to record the data to support the ISA-95 structures that will facilitate enterprise integration. For more detailed information about ISA-95 definitions and standards, refer to the ISA documentation.

You can use PEM attributes for the following:

• Create new work orders, jobs, or items.

• Generate genealogy ID to trace all the source materials of a product.

You can configure the following information in the PEM Attributes tab:

• Common Data Attributes

• Genealogy

• Production Attributes

• Extended Production Attributes

A single instance of OCO supports the definition of multiple PEM instances and each instance has specific PEM attributes. A maximum of 20 PEM instances is allowed for a single OCO instance.

For example, if we have two PEM instances Produce1 and Equip1 within the OCO instance named OCO_001, the PEM attributes are represented as follows:

OCO_001.PEMAttrs.Produce1.ProductionRequestID

OCO_001.PEMAttrs.Produce1.ProcessSegmentID

OCO_001.PEMAttrs.Produce1.Quantity

OCO_001.PEMAttrs.Equip1.EquipmentID

OCO_001.PEMAttrs.Equip1.MaterialID

OCO_001.PEMAttrs.Equip1.Quantity
