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! Not in the scanned barcode, as it is used in case of PartCheck.

• 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 Prefix + Product ID
Yes - Part number consists of Product ID + Suffix

• Operation.name.PrefixLength[i] = int

This parameter needs to be used in case there is used a prefix and a suffix as well.

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 = Yes
