You can use the panel, communication, or ASDA-Soft to read data from or write data to the data

array. Regardless of the methods, they are completed by parameter settings. The first

parameter group for reading and writing the data array is P5.011, P5.012, and P5.013. P5.011

specifies the address for reading and writing the data array. P5.012 and P5.013 are for reading

and writing the actual data contents. You can use both to read and write, but the behaviors after

reading and writing differ. Refer to Table 7.2.1.1 for more information. The second parameter

group for reading and writing the data array is P5.011 and P5.100 – P5.103. P5.011 specifies

the address for reading and writing the data array. P5.100 reads data from or writes data to the

data array address set by P5.011. P5.101 reads data from or writes data to the data array

address following the address set by P5.011. P5.102 and P5.103 work the same way. If the

address value accumulates and exceeds the maximum of 799, the returned address is 0.

You can find more details in Table 7.2.1.2.
