CLEVER AutoStart
From PlcWiki
(Automated start using RFID tags and smart watch confirmation)
Implementation documentation
v. 1.2 - 2021-01-25
version note: Workplace tags implemented
1. General description
The main purpose of the AutoStart feature is to start a product on a workplace without its scanning from a paper BoM, but using a smart watch for the confirmation, that an operator registered the new product and is going to work on it. The product is registered on a workplace by a reading of an RFID tag by an RFID reader (antenna). When the tag is read, the CLEVER Client sends a notification to a smart watch and is waiting for the confirmation back. The product is announced to an operator on the smart watch display and by a smart watch vibration. The operator touches the smart watch to confirm his readiness. The smart watch sends a confirmation back to CLEVER Client and the product is started.
2. Marriage workplace
In the very beginning of the assembly line, the marriage workplace needs to be configured. It assigns the RFID tag (mounted on each trolley) to the product (cockpit ID). That workplace is configured in a standard CLEVER Client.
See an important alternative mentioned at the end of this chapter.
An operator scans the paper BoM to start the product (a standard feature). When the RFID tag is read by a reader, the tag ID is assigned to the started product. An operation “RFID reading” (type Serial) is needed there.
To avoid a situation, when the operator scans the product ID latter than the RFID tag comes to the reader, it is possible to buffer that operation. In that case the order of these events can be opposite. At first the tag is read (and its ID is buffered) and then the operator scans the product ID. The tag ID is taken from the buffer and assigned to the product.
Following parameters are important for the RFID reading (marriage) operation:
| Parameter | Value |
|---|---|
| Send Data To Kernel | Yes |
| Buffer Enabled | Yes |
| Tolerance Over Plan | 0 |
| Default quantity condition | 1 |
Example of the Clea settings of the marriage operation:
IMPORTANT: The marriage workplace plays an absolutely key role for the entire functionality of the AutoStart system. The 100% reliably working process here is absolutely needed. It is necessary to focus on that workplace from a very beginning of the implementation.
