6 OPC UA ObjectTypes 
6.10 MaterialRejectionTrapType
6.10.4 Additional Objects of the MaterialRejectionTrapType
The following Objects are defined to extend the DeviceType.
6.10.4.1 Variable Description
The Property Description describes the rejection trap device.
6.10.4.2 Variable DisplayName
The Property DisplayName is the identification of the rejection trap device used on displaying systems, e.g. HMI and SCADA.
6.10.4.3 Variable MaterialRejectedRatio
The Variable MaterialRejectedRatio is the ratio of the total material rejected (MaterialRejectedTotal) over the total good product and is computed by the underlying system.
Remark. The unit of measure of the rejected material is the same as in the MaterialOutput (see MaterialOutputType 6.12) of the same machine module.
6.10.4.4 Variable MaterialQuantityRejectedTotal
The Variable MaterialRejectedTotal totalises the material rejected since the last time the total was reset to zero using the Method ResetRejectionTotals, see below.
The Type MaterialLotType is defined in Table 75.
The Value of the Variable MaterialQuantityRejectedTotal shall be persisted both in the OPC UA Server and in the underlying system so that, if one fails and/or is replaced, the other will allow restoring the Value when the OPC UA Server and underlying system are on separate hardware infrastructure.
6.10.4.5 Variable MaterialQuantityRejectedMasterTotal
The Variable MaterialQuantityRejectedMasterTotal totalises the material rejected and is never reset.
The Type MaterialLotType is defined in Table 75.
The Value of the Variable MaterialQuantityRejectedMasterTotal shall be persisted both in the OPC UA Server and in the underlying system so that, if one fails and/or is replaced, the other will allow restoring the Value when the OPC UA Server and underlying system are on separate hardware infrastructure.
6.10.4.6 Variable RejectionCountTotal
The Variable RejectionCountTotal totalises the number of times a rejection device was triggered to reject since the last time the total was reset to zero using the Method ResetRejectionTotals, see below.
The Value of the Variable RejectionCountTotal shall be persisted both in the OPC UA Server and in the underlying system so that, if one fails and/or is replaced, the other will allow restoring the Value when the OPC UA Server and underlying system are on separate hardware infrastructure.
6.10.4.7 Variable RejectionCountMasterTotal
The Variable RejectionCountMasterTotal totalises the number of times a rejection device was triggered to reject and is never reset.
The Value of the Variable RejectionCountTotal shall be persisted both in the OPC UA Server and in the underlying system so that, if one fails and/or is replaced, the other will allow restoring the Value when the OPC UA Server and underlying system are on separate hardware infrastructure.
6.10.4.8 Variable RejectionMode
The Property RejectionMode is True when the MaterialRejectionTrap is operational and discharges material when triggered.
6.10.4.9 Variable RejectionRatio
The Variable RejectionRatio is the ratio between the good product output total and the rejected quantity total.
6.10.4.10 Object UIInfo
The Object UIInfo contains information about the User Interface (UI) of the rejection trap. When an Object does not have own UIInfo, then the Object does not require visualisation.
6.10.4.11 Method ResetRejectionTotals
The Method ResetRejectionTotals resets the MaterialQuantityRejectedTotal and RejectionCountTotal to zero.

);
| Argument | Description |
|---|---|
| RejectionMode | When true, the rejection trap rejects. When false, the rejection trap does not reject. |
