Settings for the OPC A&E Client
[opcae] alertClassPrefix
- Type
- char
Prefix of alert classes. If you set the config entry twoStateConditionsOnly to "yes", the
client and server enable the automatic adaptation of alert classes. The alert classes have
to be structured as follows:
alertClassPrefix_AE_<Priority>
Priority is a number from 1 to 1000.
[opcae] browseOnStart
- Type
- bool
- Default
- 0
- Range
- 0|1
By default the transfer of all current server data (Event Categories, Conditions, Server
Items) during client start is deactivated. This prevents that erroneous data from the server
are automatically adopted by the client during connection establishment. With this config
entry the transfer at start-up can be activated (browseOnStart = 1). The transfer can also
be triggered manually at any time using the "Update" button in the client parameterization
panel.
[opcae] correctFutureTimes
- Type
- bool
- Default
- 0
- Range
- 0|1
Defines if future times shall be corrected or not. 0 => Do not correct the time 1 => Do
correct the time
[opcae] pollCount
- Type
- unsigned integer
- Default
- 32
- Range
- >0
Defines the number of data points that can be polled at once. If several polling requests
are queued they will be processed in the next driver cycle.
[opcae] reduPostfix
- Type
- char
Is not used.
[opcae] refreshDelay
- Type
- int
- Default
- -1
- Range
- >=-1
The AE client executes a refresh if the server state changes to RUNNING or TEST. For this
refresh a delay in seconds can be specified. The default is -1 which means that there is no
automatic refresh on state change.
[opcae] refreshMessage
- Type
- string
- Range
- -
The AE client executes a refresh if server indicates that refresh is needed using the
event message specified with this config entry. e.g. refreshMessage = "I need refresh" Per
default this entry is empty, which means that the client does not execute a refresh
depending on simple event messages.
[opcae] server
- Type
- string
Defines the datapoint for the A&E server. Several this kind of entries can exist for
the OPC A&E client of WinCC OA since the client can process alerts/events of several OPC
A&E servers.
[opcae] sourceSeparator
- Type
- char
- Default
- .
Separator used by the server for the items. The source separator separates the items
passed by the server during the browsing into elements. The default is a dot ("."). The
client also has to use this separator (for example, PVLEVEL4.Level1). An arbitrary separator
can be used.
[opcae] startDelay
- Type
- int
- Default
- 0
With the entry startDelay the setting of the manager state "running" can be delayed to
avoid that subsequent managers, depending on the OPC AE client start, are started too early.
