Why a sheet
“Connecting machines” can mean reading a counter, receiving alarms or driving a recipe. Each case needs different data, a different protocol and a different owner.
- NeedRead, alert or drive
- Interface sheetEvents, identifiers, security
- PrototypeOne machine, real messages
- Conclusive test?Yes: quote. No: another solution.
- DeploymentMachine by machine
The questions on the sheet
- Which event triggers the exchange, and in which direction?
- Which identifiers link the machine to the order, the lot and the work center?
- What frequency, what volume and what acceptable delay?
- Who secures the network and access?
- What happens in case of an outage, a duplicate or a lost message?
Test before committing
A prototype on one machine, with real messages and simulated failures, is worth more than a compatibility promise. The test result sets the deployment quote.
Limits
Machine interfaces remain to be assessed at Omnifloo Prod: no compatibility is announced without a sheet and a test.
