Scan Transfers
Data Type A minimum of 512 equivalent words of each data type specified in the Additional
State RAM area are sent in a scan, unless there are less than 512 words of that data
type left to be transferred. For example, if you specify 528 additional registers to be
transferred over three scans, the system will send the data faster than expected.
The first 512 additional registers are transferred in the first scan, and the remaining
16 registers are transferred in the second scan. On the third scan, the process
begins again, sending the first 512 additional registers.
