CJ-series PROFINET IO Controller Unit Operation Manual for NJ-series CPU Unit (W511)
Additional Information
The start address of Output area 1 in the example remains the same after adding an I/O module.
Re-allocating I/O Modules
After setting up the initial I/O configuration, the I/O modules can be re-mapped to the second
Input/Output area. This can be accomplished by using drag & drop to move the I/O modules. To
accomplish this, perform the following sequence:
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.
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 modules 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 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.
Example
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).
