Repeated scanning in PLC client

Generally, it is not possible to scan the same barcode twice. It is a protection against a clumsy manipulation with a scanner. An exeption are some control barcodes, which can be scanned repeatedly if the scanning has an error.

In some cases it is necessary to enable the repeated scanning on a workstation. It is defined by the following parameter:

WorkPlace.RepeatedScanningAllowed = Yes | No

Blocking of tightening machine in case of "Product not completed"

Sometimes it can be useful to block the tightening machine when the following product ID is scanned and the current product is not yet finished. If the tightening machine is blocked in this situation, that fact takes an attention of an operator. Then he needs to scan a special control bar code (PLCUBNCTM) to release it.

This feature is useful especially for workstations, where a fixed scanner is used.

This feature is defined in the client configuration file by the following parameter:

WorkPlace.Tightening.StopWhenIncompleteProduct = Yes | No

If the spindle is blocked because of this reason, it is necessary to use the above mentioned control bar code. The standard bar code PLCUBTM doesn´t work in this situation.
