TRANSMISSION DATA DESCRIPTIONS

The DIP SW located at the side of the module switches the unit's data allocation mode.

The Data Allocation Mode 1 is used when all analog I/O modules are single-channel types. In this mode, one (1) word is

assigned for one I/O module. The second channel on the dual-channel modules cannot be used.

The Data Allocation Mode 2 is used when one or more analog I/O modules are dual-channel types. 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

In Data Allocation Mode 1, a maximum of 16 I/O modules can be mounted per node. If two-channel type analog modules are

mixed, the second channel I/O cannot be used.

In Data Allocation Mode 2, a maximum of 8 I/O modules can be mounted per node.

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

input or output. If a module for Data Allocation Mode 2 is used, the second channel data is not transmitted.

An input module stores data in the output data area. The input data area is secured for the module but not used.
