Auto Addressing and Re-
allocating I/O Modules
Example
100
3 After setting up the initial I/O configuration, all I/O modules will be shown in
the overall list in the upper half of the Slave Area tab. This is a pick list from
which modules can be selected. The allocated I/O modules are listed in
area 1, the column on the left of the lower half of the window.
The I/O modules in the pick list, all remain there. The allocated I/O mod-
ules are copies of the modules selected from the pick list.
4 In order to move an I/O module from one area to another, select the
module in the pick list.
5 Hold the left mouse button and drag the I/O module to the Input/Output
area of choice. Release the left mouse button to drop the module in place.
The area to place the module in must be empty. The area to put the mod-
ules in does not need to be selected first.
Auto Addressing (re)allocates I/O modules in all Input/Output areas. If - after
setting up the initial I/O configuration - two or more I/O modules are moved
from one area to another, Auto Addressing maintains the same sequence, i.e.
the slave device with the lowest address and its I/O modules in the selected
sequence are allocated before a slave device with a higher address.
In the figure below two output modules from the initial I/O configuration (top
window) have been re-allocated to Output area 2 (bottom window)
