Appendix A.1. 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 2nd Stage, 2nd Stage data is moved to 3rd stage and 3rd stage data is lost.
