When the A1SJ71UC24-R4 with the software version X or later, the A1ADP-SP setting can be used.
This setting is used to create a sequence program in the non-procedural mode by using the dedicated instructions for the
computer link function in the AnACPU.
When using the dedicated instructions for the computer link module, switch the A1ADP-SP setting to ON. When not using
them, switch the setting to OFF.
When the A1SJ71UC24-R4 with the software version W or earlier is used, the dedicated instructions for the computer link
function cannot be used.
