CableCheck (Poka-Yoke Check)

From PlcWiki

Generally, this type of an operation checks if the scanned barcode matches the product ID. It can be called a unique part check. The scanned bar code (or its substring) needs to match the product ID (or its substring).

Mandatory parameters

• Operation.name.Type = CableCheck
• Operation.name.Index = (int) index

Other parameters

Bar code settings

• Operation.name.SelectPattern[i] = Regexp
• Operation.name.PartStart[i] = int
• Operation.name.PartLength[i] = int

These two parameters (in case of an operation type CableCheck) define the start position and the substring length in the product ID.

• Operation.name.CheckSumType[i] = int

Possible values of CheckSumType:
0 - No check (default settings)
1 - SumEven + 3*SumOdd MOD 10
2 - SumEven + 3*SumOdd MOD 36
3 - Sum MOD 43 (Code39)

• Operation.name.SNStore = No | Yes

This parameter is used here to define if the part bar code is different by its prefix or suffix:
No  - Part number consists of Product ID + Suffix
Yes - Part number consists of Prefix + Product ID

Examples

1. The part number consists of a product ID + suffix "ABC":
Product ID: 1234567
Tested Part number: 1234567ABC
Settings:
Operation.MainHarness.Type = CableCheck
Operation.MainHarness.Index = 1
Operation.MainHarness.SelectPattern[0] = ^\d{7}ABC$
Operation.MainHarness.SNStore = No
