Appendix A.1. How Client Stores Data:

The HCS will be polled by an RDBC Map Descriptor and data will be stored in the DA_Current Data Array in the
following fashion if parameter HCSR_Data_Stages >1:
New data is stored as current data.
If data is changed, last current data is moved to 2
data is lost.
When a vehicle has HCS-R equipment installed, Byte 7 (Status of the loop) is equivalent to the "From Loop (0),
On Loop (1) byte listed in Appendix A.1.1. The 20th offset will hold whether data is From Loop or On Loop. To
achieve this, the FieldServer should be configured to store On-Loop and From-Loop data in the same Data
Array. i.e. Map Descriptor Parameter HSCR_Onfrom should be set to Onfrom. Refer to Section 5.3.2
