5-5 How to block-transfer any single block of data
The following describes a method of reading any single block of data to block data storage area on the
JW50H/70H/100H control module input section from shared RAM on JW-12PS/14PS, and transferring
that block data to block data storage area on the JW50H/70H/100H control module output section. In
this example, the read/write section of the block data is added to the "transfer to relay area" sample
ladder program on the previous page.
[Example]The content of X-axis parameter 1 is read to the JW50H/70H/100H control module from
JW-14PS on JW-14PS (top address 49000) on page 5-26, and that data is transferred to
the write area to write the data.
