RSLogix will automatically apply the slot number change to all tags, variables
and ladder logic rungs that use the MVI56E-MCM slot number for computation.
Adjust the Input and Output Array Sizes
Note: The following steps are only required if you are using the sample ladder logic (RSLogix
version 15 or older) rather than the Add-On Instruction (RSLogix version 16 or newer).
1 Click ReadData to open ladder file and go to rung #2 of this file.
2 Change the High Limit on the LIM
statement to allow for 5 blocks of data, as
shown in the following illustration.
(1000 registers / 200 registers per block = 5 blocks of data)
3 Verify the change to this rung. Toggle the object within RSLogix 5000.
4 Save and download ladder to the processor.
5 When Online with the ControlLogix processor, toggle the
MCM.CONTROL.W ARM B OOT bit to download the changes to the processor.
Downloading the Sample Program to the Processor

with the processor.
2 When communication is established, RSLogix will open a confirmation dialog
box. Click the D OWNLOAD button to transfer the sample program to the
processor.
