Appendix B.6. Driver Stats

EGD producers produce data messages for Server devices to consume. The type and frequency of the messages
depends on the producer configuration.
PLC_READ_MSG_RECD statistic. Other legal messages which do not contain data of interest are discarded and are
counted as the MSG_IGNORED statistic. The PLC_READ_MSG_RECD statistic is incremented once by each Map
Descriptor which extracts data from an incoming message. Thus, one incoming message and three associated Map
Descriptors would cause the statistic to increase by three (when viewed from the connection's point of view.)
This driver can 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 "EGD-stats".
The following example shows how this special Map Descriptor can be configured.
Nodes
Node_Name
Null_Node
Data_Arrays
Data_Array_Name
EGD_STATS
Map_Descriptors
Map_Descriptor_Name
egd-stats
This Map Descriptor instructs the driver to use the Data Array EGD_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.
