I/O Allocation Using the Parameter Wizard (Simple I/O Allocation)

• I/O in PLC memory can be allocated to slaves simply and interactively.
• I/O allocation is as follows: In order of node addresses, simple I/O allocation from Block 1, and I/O allo-
cation of 100-word blocks.
Allocation is performed in the order of slave node addresses from Block 1 (allocating from Block 2 when
Block 1 is completely allocated) with a block size of 100 words.
Note: After allocating I/O using this wizard, node addresses can be changed and other allocation changes
can be made in the Editing Parameters, as described later.
The Parameter Wizard specifies the beginning address of each block (the block size is always 100 words),
the allocation method (allocation by word or minimum allocation of unused words), and slave registration or
deletion.
Note: – Allocate areas larger than 100 words for each block in Editing Parameters.
– Use the following procedure to allocate I/O to the slave devices of a master device with the Param-
eter Wizard.
1. Select the master device to register.
2. Select Device - Parameter - Wizard.
3. Click the Yes Button.
The present settings will all be initialized if the Parameter Wizard is used for the setup. A confirmation
dialog box will be displayed. An example is shown below.
4. Setting the Start Word for Each Block
The Scan List Wizard-Setting Memory Block's Start Word Window will be displayed. An example is
shown below.
Set the memory areas to use and the start words, and then click the Next Button. Allocation starts auto-
matically from Block 1. If Block 1 is completely allocated, allocation will be performed in Block 2. Each
block will be allocated from the start word to a maximum of 100 words (fixed).
Note: If an area overlaps blocks or the start word results in exceeding the memory area range, you cannot
move to the next step.
