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.
Note The area to place the module in must be empty. The area to put the modules in does not
need to be selected first.
Auto Addressing and Re-allocating I/O Modules
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 main-
tains 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).
