MODBUS FUNCTION CODES & SUPPORTED CODES

MODBUS I/O ASSIGNMENT
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.
For discrete I/O, 16-channel area is automatically assigned to each module. With a 4-channel module, the bits assigned to ch.
5 through 16 remain “0.”
