3. Data Array called DA Scale The 1 element converted from the ASCII steam will be store at offset zero in the Data Array The driver will convert and store floating point numbers because the data_type is a floating point type A maximum of 10 number fields can be processed and stored The driver only converts and stores the data when the ASCII stream ends Read appendix xxxxxx to learn how the driver knows when a stream has ended and it should process and strore data Map_Descriptors Map_Descriptor_ Name Data_Array_Name Data_Array_Offset Function Node_name Data_Type Length Store Weights DA_Scale 0 Passive ode_A Float Reg 10 A maximum of 10 value items will be stored Driver waits passively Connects this Map for incoming data Descriptor to a Node There is no polling Descriptor which in turn points to a connection descriptor The name of the Map Descriptor Data Array where Names do not the incoming data need to be unique should be stored but making them so may facilitate trouble shooting When the driver processes the stream it should in this case treat the data as floating point data Ensure that the format of the Data is suitable to store a floating point value The 1 element of converted data will be stored at this location in the DA Subsequent data is stored in consecutive locations FieldServer Technologies 1991 Tarob Court Milpitas California 95035 USA We
