Configuring the IO Controller
Removing Gaps from the
I/O Mapping
Compressing the I/O
Mapping
Note: Auto-Addressing is disabled
Since gaps in the I/O mapping are generally undesirable, the CJ1W-PNT21 IO
Controller DTM provides a means to remove all gaps, after finalizing the I/O
mapping procedure. This removal is accomplished by compressing the I/O
modules in a particular area.
Compressing re-allocates all I/O modules in an area as close to the start of the
area as possible. Compressing an area does not change the sequence of the
slave devices and/or the I/O modules. It only removes the unused memory
gaps. Compressing can be initiated for each area individually.
In order to compress an area, perform the following sequence.
1,2,3... 1 Open the CJ1W-PNT21 IO Controller DTM - Configuration User Interface.
2 Select the IO Device Area sub item. The window shows two sub tabs: One
for Output Allocation and one for Input Allocation. The following points
apply to each of these tabs.

The second Output modules
of IO Device #3 and #4
were moved to Output area 2,
leaving a gap in Output Area1.
