specified format/ requested data type and the canonical data
type. |
| OpcClamp |

A value passed to WRITE was accepted but the output
was clamped. |
| OpcDataQueueOverflow |

Indicates that not every detected change has been
returned for this item. This is an indicator that servers buffer
reached its limit and had to purge out the oldest data. Only the
most recent data is provided. The server should only remove the

the buffer. This will allow single samplings of older items to be
returned to the client. |

item. |

occurs, it is due to a programming error in the client or possibly
in the server. |
