About General-purpose Input/Output
General-purpose input/output, too, are accessible by using system
variables for I/O, such as M_In and M_Out.
However, you are not permitted to make such
access as spans beyond the region used in PROFIBUS, like 1999,
by using variables which access a plurality of bits, including M_Inb, M_Inw, M_Outb, and M_Outw. Ensure that
your programming stays within the region ranging from 2000 and 3951.
Correct examp
le: M_In (2000), M_Inb (2010), M_Out (3000), M_Outb (3010), etc.
Incorrect example: M_Inb(1999), M_Inw (5070)
、
M_Outb (1999), M_Outw (1999), etc.
