OPC UA Write Errors
The following explains errors that can occur when Web HMI performs data writes to data sources.
Error | Description |
---|---|
BadCommunicationError OpcUa_BadServerNotConnected | There is a problem with the connection to the HMI/SCADA system. |
BadOutOfService | The tag or point is not currently enabled or available. |
BadNotWritable | The tag or point does not allow writes. |
BadOutOfRange | The value being written exceeds the range of the tag or point. In the case of text data, the text exceeds the maximum length. |
BadIdentityTokenInvalid | There was a problem with the security token used to authenticate the Web HMI user with the HMI/SCADA system. |
BadIdentityTokenRejected | The user is not authorized to connect to the HMI/SCADA system. Verify there is an account for that user on the HMI/SCADA system. |
BadResourceUnavailable | A required resource is not available. For iFIX, this specifically means that iFIX cannot connect to the Web HMI authentication service to validate the user. In some cases, this can happen if the secmgr.cclr.dll.config file n the iFIX install folder on the SCADA node contains an incorrect host or port for the Web HMI server. |
BadNodeIdInvalid | The data source name that was specified as the source for the asset’s property is incorrect. This pertains to CIMPLICITY OPC UA data sources. |
BadTypeMismatch | The value being written does not match the data type of the tag or point. |
BadUserAccessDenied | The user name does not have permissions to write to the point in the CIMPLICITY project. |
