Introduction
This Tech Note outlines how to configure the Wonderware MES Operations Capability Object (OCO) Production Counters to count against multiple jobs running on the same entity.
Application Version:
Wonderware MES v4.0
Configuration: Entity and OCO Modeling
An OCO must be contained by a User Defined Object (UDO) that represents an MES Entity (Figure 1 below).
FIGURE 1: MES ENTITYAND OCO MODELING
OCO General Configuration
In order for an OCO to be configured for Production Counters, you must enable the Entity Can Run Jobs and Enable Production Counters options in the General tab panel (Figure 2 below).
FIGURE 2: OCO GENERAL CONFIGURATION
You can configure an MES Entity to run multiple jobs simultaneously by clicking the Job Defaults tab and typing a number in the Number of Simultaneous Jobs That Can Run On This Entity field (Figure 3 below).

Note: The practical limit is about 50 jobs running on one entity at any one time.
If desired, you can also indicate a default Reason, Storage Entity, Lot Number, Sublot Number, etc. for production when it is recorded to the MES database.
OCO Production Counter Configuration
When you configure a Production Counter, one instance of the counter is automatically created for each job position. In this example, the OCO was configured for 3 job positions. Now that a Production Counter has been created, you can see that the counter instance can be selected in the Job Position list (Figure 4 below).
FIGURE 4: PRODUCTION COUNTER INSTANCES
It is important to understand that the Job Position drop box is provided to select which instance to edit. The number is NOT an attribute of the counter (note the lack of the attribute lock option).
When you select the instance, the editor refreshes the display to include all the attributes for that instance. For example, you may want the production from each job position to have different lot numbers. You would select each Job Position instance and configure the To Lot attribute for that instance of the counter. Figure 5 (below) shows each To Lot attribute with a different Input Source defined.

FIGURE 5: CONFIGURING PRODUCTION COUNTER INSTANCES
Each instance of the Production Counter will now has its own set of attributes, indicated by JobExec.JobPos<JobPos#>.Prod.<CounterName>. <Attribute Name> (Figure 6 below).

Runtime Operation Example
For Job Execution, you can start a Job via the OCO and assign it to run at a specific Job Position. If the jobs are not started by the OCO, scripting must be provided in order to
Populate the attributes that the counters use to know which job to record the production against, and Which item to record as produced.

JobExec.JobPos<JobPos#>.SequenceNumber JobExec.JobPos<JobPos#>.Item
In this example, three jobs are ready to run on the MES_Entity_001 entity, viewed in the Operator client (Figure 7 below).
FIGURE 7: JOBS READYTO RUN
The jobs can be started by the OCO by first defining the job to start and triggering the JobExec.StartJobCmd attribute. The following attributes define what job to execute the start command against (Figure 8 below).
FIGURE 8: ATTRIBUTESTO STARTA JOBVIATHE OCO
After setting the information for each job, defining the job position to run on, and starting the job, there are now three jobs running on the entity (Figure 9 below).
FIGURE 9: JOBSARE RUNNING
Looking the OCO attributes in Object Viewer, you see the attributes are now populated. Also populated are CurWoId, CurOperId, and CurSeqNo. These attributes are simply read-backs from the MES database and provided for informational purposes (Figure 10 below).

FIGURE 10: OCO ATTRIBUTESWITH RUNNING JOBS
You can now add production to these running jobs. In this example, we will use the Absolute Counters. Production is added by specifying a value for the counter.
Absolute Counter Value: JobExec.JobPos<JobPos#>.Prod.<CounterName>.AddProdQtyAbs Then that value is recorded to the MES database by setting the trigger to true.
Absolute Counter Trigger: JobExec.JobPos<JobPos#>.Prod.<CounterName>.AddProdQtyAbsCmd
A different produced quantity for each job is shown in Figure 11 (below). Note that the attribute JobExec.JobPos<JobPos#>.QtyProd is now reporting back the total quantity produced for that job.
