(2) The transfer is available even if there is an overlap between the source and destination devices.
For the transmission to the smaller number of device, the data is transferred from
number of device, the data is transferred from
However, as shown in the example below, when transferring data from R to ZR, or from ZR to R, the range to be
transferred (source) and the range of destination must not overlap.
• ZR transfer range ((specified head No. of ZR) to (specified head No. of ZR + the number of transfers -1))
• R transfer range ((specified head No. of R + file register block No. 32768) to (specified head No. of R + file register
block No. 32768 + the number of transfers -1))
Example
Transfer ranges of ZR and R overlap when transferring 10000 points of data from ZR30000 (source) to
R10 (block No.1 of the destination).
• ZR transfer range
• R transfer range (10+(1 32768)) to (10+(1 32768)+10000-1)
Therefore, the range 32778 to 39999 overlaps.
