By default, the data is mapped to Area 1 in both the Output and Input
Allocation tabs. It is however possible to map a part of the data to the second
area in the same tab. For example, an application may require to store all byte
data in one location and all word data in another.
Moving data mapped in one Area to another Area is done from the module list.
The procedure is as follows:
1 Find and select the module to be mapped from module list.
2 Left-click the module and drag it, while holding the Left mouse button, to
3 Release the mouse button. The module data is copied to the desired Area

pressing the Compress button (only after all modifications to the mapping have
been made).
Control
The start address and length definitions of the data block cause it to exceed
the memory area in the PLC.
The data mapping of two or more I/O Areas (Output and/or Input) overlap
each other partly or totally in the PLC memory.
The length box allows the user to select the number of visible
rows. The minimum and the default value is 100 words.
The Length value can be set to up to 7168 words.
This field displays the actual length of the data block (not
necessarily the same as the amount of data contained by it).
This length includes both data as well as any gaps between
modules. Gaps may only be there if the Auto-Addressing
option in the Master Setup tab is disabled (See also Note 2).
Pressing the Compress button will compress the Area list
associated with it, that is gaps from the mapping list are
removed by moving all mapped I/O modules as close as pos-
sible to the beginning of the memory area. (See Notes 3 and
4).
