TRANSMISSION DATA DESCRIPTIONS

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

In the Data Allocation Mode 1, one (1) word is assigned per module. The second channel of analog I/O modules cannot be used.

In the Data Allocation Mode 2, two (2) words are assigned per module regardless of whether the second word area is required

or not, even for discrete I/O modules that require one (1) word.

A maximum of 32 I/O modules can be mounted per node.
