By default, the data is mapped to Area 1 in both the Output and Input Alloca-
tion 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 the module which must be mapped to a desired Area in the module
list, and select it.
2. Left-click the module and drag it, while holding the Left mouse button, to
the desired Area. This can be the end of the list or any empty space in the
list in which it will fit (See Note).
3. Release the mouse button. The module data is copied in the desired Area
and appended to the already existing list. The same entry in the other list
is now deleted.
4. Finally, the PLC memory address to which the module is mapped is now
updated in the module list.
Note 1. If Auto-Addressing is enabled (see Master Setup tab in this section), any
empty spaces evolving out of moving of modules to another Area will be
removed by compressing the list. Modules located to a higher address will
be moved to a lower address to fill up the gap.
2. If Auto-Addressing is disabled, compressing the list can be accomplished
by pressing the Compress button, after all modifications to the mapping
have been made.
The Advanced tab displays the settings required for PROFIBUS DP-V1 Class
2 communication with Slave devices. The Advanced tab is shown below.
The Acyclic Connection/Abort status box contains settings, which allow the
user to define where in the PLC CPU memory the Connection/Abort status bit
fields must be mapped. These bits indicated the open/closed PROFIBUS DP-
V1 Class 2 connections between the Master Unit and individual slave devices.
