Input data start address area
■
Input data start address area (Un\G22784 to Un\G22847)
This area stores the start address (buffer memory address) for input data from DP-Slaves.
Writing a program with 'Input data start address area' (Un\G22784 to Un\G22847) allows specifying addresses in input data
area regardless of the number of input points of DP-Slaves.
Input data start address area stores information on 64 stations in the same sorting order of data.
Output data start address area
■ Output data start address area (Un\G22912 to Un\G22975)
This area stores the start address (buffer memory address) for output data to DP-Slaves.
Writing a program with 'Output data start address area' (Un\G22912 to Un\G22975) allows specifying addresses in output
data area regardless of the number of output points of DP-Slaves.
Output data start address area stores information on 64 stations in the same sorting order of data.
