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.

DATA ALLOCATION MODE 1

Total number of modules equal the assigned I/O points with

Data Allocation Mode 1. I/O modules can be allocated from

I/O Module Slot No. 1.

When I/O signals are to be mixed, the former half slots are

assigned to the inputs and the latter half are to the outputs.

For example, if you have selected ‘8’ I/O points and ‘mixed’

I/O type, the inputs must be located among I/O Module Slot

No. 1 through 4, and the output among No. 5 through 8.
