4.6Map Descriptor Example: Write Controls

The following Map Descriptor will write controls to physical Server Genisys_01 and Genisys_02 (described in Client Side Node Descriptors section) whenever any of the control statuses changes/updates. One such Map Descriptor is required per Node.

If Data_Type is Byte, 32 consecutive locations from the Data Array will be written to VHLC. Data at any location would be considered as one control word.

If Data_Type is Bit, 256 consecutive locations from the Data Array will be written to VHLC. Data at 8 consecutive locations would be considered as one control word.

Also see Appendix A.1.
