DATA ALLOCATION MODE
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 as-
signed 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 discrete I/O, 16-channel area is automatically assigned to each module. For example, with a 4-channel module, the bits
assigned to ch. 5 through 16 remain "0."
