ASDA Series Application Note Introduction of PR Operation If the size of mapping content is 32-bit, a mapping parameter can map one parameter which has the size of 32-bit. For example, P1-09 is a 32-bit parameter. Enter 0x0109 in both high-word and low-word of P0-35, the content of P1-09 will all be mapped to P0-25. Index of Mapping Parameter P0-35 Mapping Parameter 32-bit Parameters P0-25 P1-09 H-Word P1-09 L-Word Figure 1.8 Example of Mapping a 32-bit Parameter If respectively specifying a 32-bit parameter in low-word and high-word of the mapping index, the mapping content will only show the low-word part of each 32-bit parameter.
For example, P1-09 and P1-10 are both 32-bit; writing 0x0109 into low-word of P0-38, low-word part of P1-09 will be mapped into the low-word part of P0-28. Writing 0x010A into high-word of P0-38, the low-word part of P1-10 will be mapped into the high-word part of P0-28. See Figure 1.9.

This can be done by selecting the items from the drop-down list of each channel on PC scope.
