7. Driver Notes
7.1 IC_Timeout
The connection IC_Timeout must be set to zero. This is done in the CSV file by setting
IC_Timeout parameter.
The following fragment from a CSV file illustrates how this is done.
7.2 Driver Stats
In addition to the standard FieldServer communication statistics described in the FieldServer
User’s Manual, the Gamewell Serial 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 "Gamewell-stats" .
The following example shows how this special map descriptor can be configured. You can copy
this section of text directly into your CSV file.
Nodes
Node_name , Node_ID, Protocol
dummy_node, 0 , Gamewell
Data_Arrays
Data_Array_Name , Data_Format, Data_Array_Length
DA_GAMEWELL_STATS, uint16 , 500
Map_Descriptors
Map_Descriptor_Name, Data_Array_Name , Data_Array_Offset, Function, node_name ,
Gamewell-Stats , DA_GAMEWELL_STATS, 0 , passive , dummy_node,
When the driver sees this map descriptor it uses the data array DA_GAMEWELL_STATS (in this
example) to store driver specific statistics. Only one of these map descriptors may be specified
per FieldServer.
The offset into the array is based on the port number. 30 arrays locations are used per port.
The offset is obtained by multiplying the port number by 30.
Connections
Port, Baud, Parity, Data_Bits, Stop_Bits, IC_Timeout
P1, 2400, None , 8 , 1 , 0
