CS1/CJ1W-PRM21 PROFIBUS Master DTM
Section 2-3
3.
The
Compress
button will be disabled, i.e. grayed out, when Auto-Ad-
dressing (see
Master Setup Tab
on page 31) has been enabled.
4.
Before Compressing, the Master DTM will display a warning message
prompting the user for confirmation of the action.
Changing Mapped Data
Allocations
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.
1,2,3...
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.
Additional functions
As of Master DTM version V2.xx two additional functions are provided to the
user, via the DTM context menu:
• Slave DTM Address Assignment
• Set Device Station Address (only available for CS1/CJ1W-PRM21 Unit

To select these options perform the following steps:
1,2,3...
1.

2.
Right click the mouse, and select the
Additional functions
entry from the
context menu.
3.
Select the desired function.
