Link Operations Definitions Together Into a Route 3.0

Overview

Often process steps are joined in a consistent route through possible processes. Operation Definitions can be joined to form such routes to match operational practice.

Frequently a Bill of Process is defined or required in an application. Routes provides the ISA-95 instantiation of a Bill of Process.

Scripting

The following python code snippet joins the "Mix Nuts" operation to the "Package Nuts" operation.

Trigger Property Creation Example

Code

#Example to link two operation definition together
od1 = system.mes.loadMESObject('Mix Nuts', 'OperationsDefinition')
od2 = system.mes.loadMESObject('Package Nuts', 'OperationsDefinition')
trigProp = od2.createComplexProperty('TriggerOperBegin', 'Trigger')
trigProp.setPrecedingRefType(od1.getMESObjectType().getName())
trigProp.setPrecedingRefUUID(od1.getUUID())
trigProp.setMode('At Operation End')
trigProp.setDefault(True)
objList = system.mes.object.list.createList()
objList.add(od1)
objList.add(od2)
system.mes.saveMESObjects(objList)

Code

##Suggest this script is utilized while looping through a list of Operations:
opName = 'Operation Name'
nextOpName = None
rate = 100.0
someCounter = 1	
	
## Load the Base Operation Definition and Segment
baseOpDef = system.mes.loadMESObject(opName, 'OperationsDefinition')
baseOpSeg = system.mes.loadMESObject(opName, 'OperationsSegment')

## Derive an Operation Definition for use in the Route from the Base Operation Definition
list = system.mes.deriveOperation(baseDef)
## Get the objects from the MES Object List Derived and Assign Names
newName = '%s_%s_%s' % (routeName, someCounter, opName)
newOpDef = list.get(0)
newOpDef.setPropertyValue('Name', newName)
newOpSeg = list.get(1)
newOpSeg.setPropertyValue('Name', newName)

## Suggest adding custom properties and possibly rework step if appropriate.

## Set the Material Out Lot Equipment Reference to the Equipment reference for the next operation.
if nextOpName is not None:
	nextOpSeg = system.mes.loadMESObject(nextOpName, 'OperationsSegment')
	nextOpSegEq = nextOp.getEquipment()
	matProp = newOpSeg.getComplexProperty('Material', 'Material Out')
	matProp.setEquipmentRefType(nextOpSegEq.getMESObjectType().getName())
	matProp.setEquipmentRefUUID(nextOpSegEq.getUUID())

## Set the appropriate production rate
matProp = newOp.getComplexProperty('Material', 'Material Out')
matProp.setRatePeriod('Hour')
matProp.setRate(float(rate))
			
## Assign the Trigger Property when route building with multiple operation definitions
#tripProp = newOpDef.createComplexProperty('TriggerOperBegin', 'Begin Trigger')
#tripProp.setMode('At Operation End')
#tripProp.setAuto(False)
#tripProp.setDefault(True)
#tripProp.setPrecedingRefType('OperationsDefinition')
#tripProp.setPrecedingRefUUID(preOp)

## Save MES Objects to manifest changes
system.mes.saveMESObject(newOpDef)
system.mes.saveMESObject(newOpSeg)
	
print 'Process Successful'
