3) Purpose
(1) System area
It used to save the self-producing data of the CPU module for the system management and GMWIN system control
data.
(2) System flag area
It used to save the user flags and system flags. The user operates it by flag names.
(3) Input image area
It used to save input data read from input modules. Overall size is %IX0.0.0~%IX0.7.63. Only %QX0.0.0~%QX0.3.63
can be used as a real input domain but the other unused domain can be used as convenience, especially remote
output data for communication can be saved here as convenience.
(4) Output image area
It used to save operation results that are automatically output through the output device. Overall data size
is %QX0.0.0~%QX1.7.63. In GM7U, only %QX0.0.0~%QX0.3.63 can be used as a real input domain but the other
unused domain can be used as convenience, especially remote output data for communication can be saved here as
convenience.
(5) Direct variable area
The user can use this area to access direct memory data, using the variable names such as %MX0, %MB0,
and %MW0, %MD0, which was defined in advance by the system. Memory size is defined when the user makes
program. Refers to “system definitions” for the variable area available to use according to the setting.
(6) Symbolic variable area
It used to save the variables that when the user creates a program or when the user defines a global variables, is
automatically allocated its memory. The variables used in program blocks are located in the ‘PB instance memory’ of
the related program, and the memory used in the function block is located in the ‘FB instance memory.’
