Examples

Get Messages by Unit Path

The use case for this script function is when an operator oversees multiple Units that can be running various batch recipes. It will return all messages for Batch Recipes that are active for the specified Unit(s).

Copy Code

Python

msgList = system.mes.batch.queue.getMessages('Enterprise\Site\Area\Process Cell\Unit ?')
for m in msgList:
	print(m)

The unit path can contain * for multiple character wildcard or ? for single character wildcard.

The unit path can contain multiple paths.
For example:

'Enterprise\Site\Area\Process Cell\Unit 1, Enterprise\Site\Area\Process Cell\Unit 2'

Get Messages by Batch Recipe

The use case for this script function is when an operator oversees or is just interested in viewing messages for a single batch recipe at a time. It will return all the messages for a single Batch Recipe that is active.

Copy Code

Python

qList = system.mes.batch.queue.getEntries(0, 1000, '')
for q in qList:
	msgList = system.mes.batch.queue.getMessages(q)
	for m in msgList:
		print(m)

Acknowledge a Message

Copy Code

Python

qList = system.mes.batch.queue.getEntries(0, 1000, '')
for q in qList:
	msgList = system.mes.batch.queue.getMessages(q)
	for m in msgList:
		if m.getStepName() == 'O6' and not m.hasAckBy():
			m.setAckBy('Tom')
			system.mes.batch.queue.acknowledgeMessage(m)
			break
