Bus Error Objects
SUMMARY
Bus Error Objects are Data Objects that are kept locally; only acknowledged alarms are synchronized between the Operator Stations not their values.CONTENTS
Description
Bus error objects are Data Objects (usually PVs, type ‘Alarm’, value
type ‘Integer’) used to indicate the bus condition of the single
stations.
The name of the Bus Error Object defined for a Station can be found below
'Error Object-Id' (Visu2000) respectively 'Station Error Object' (AbvProNT)
in the properties of a station.
A Bus error object belongs to the Data Objects that are kept locally;
only acknowledged alarms are synchronized between the Operator Stations not
their values.
To facilitate such local objects they must be allocated to a special station
with the following parameters: Station number '100', type 'Process Server'.
| Value of the Bus Error Object | Standard System (1 Bus) | Redundant System (2 Busses) |
|---|---|---|
| 0 | No connection | No connection |
| 1 | Connection okay | Bus 1 okay |
| 2 | - | Bus 2 okay |
| 3 | - | Both connections okay |
