TRANSMISSION DATA DESCRIPTIONS

The DIP SW located at the side of the module must be turned OFF.

Data Allogcation Mode 2 is used for the R5-ND2. In this mode, two (2) words are assigned for one I/O module regardless of

whether the second word area is required or not. For example, discrete I/O modules require only one (1) word, but two (2)

words are automatically assigned to these modules.

■ I/O CAPACITY

A maximum of 16 I/O modules can be mounted per node.

DATA ALLOCATION MODE 2

Address

The area enclosed with a bold line is assigned for I/O data.

Each module takes two-word areas for input and output respectively, regardless of whether the module type is input or output.

If a module for Data Allocation Mode 1 is used, all the bits for Module n+1 data turn to "0" (unused).

Each module can handle either input or output data. Input and output cannot be mixed in one module.

Input data from the master device is transferred to the module's output data area. The master device can read from the output

data area the data it has set.
