6.5 Driver Stats
In addition to the standard FieldServer communication statistics described in the FieldServer
User’s Manual the Optomux Driver can also
expose some driver statistics by writing data to
a data array. A special map descriptor is required. The driver recognizes the map
descriptor by its name which must be "opto22-stats" .
The following example shows how this special map descriptor can be configured.
Nodes
Node_name, Node_ID, Protocol
null_node, 0 , Optomux
Data_Arrays
Data_Array_Name, Data_Format, Data_Array_Length
OPTO22_STATS , UINT32 , 300
Map_Descriptors
Map_descriptor_Name, Data_Array_Name, Node_name, length
Opto22-stats , OPTO22_STATS , null_node , 300
When the driver sees this map descriptor it uses the data array SK_STATS (in this
example) to store driver specific statistics. Only one of these map descriptors may be
specified per FieldServer.
The driver stores the following data.
