With the offset parameters listed above, the Modbus Master could read from coils
10001 to 10176 using the tags MCM.DATA.WRITEDATA[0] TO [9]. The Master
could also read from address 30001 to 30490, and the data contained in those
Modbus addresses would come from the tags MCM.DATA.WRITEDATA[10] TO
[499] within the ControlLogix program.
The Master could then write to coils addressing 0001 to 0160 and this data would
reside within the ControlLogix program in tags MCM.DATA.READDATA[0] TO [9].
The Master could then write to registers using Modbus addresses 40001 to
40590, and this information would reside in addresses
MCM.DATA.READDATA[10] TO [599].
Note: The offset parameter only sets the starting location for the data. As shown above, if the
Master issues a Write command to address 40001, the data will go into the ControlLogix processor
at address MCM.DATA.READDATA[10].
Likewise, a Write To bit address 0161 will also change to address
MCM.DATA.READDATA[10].0 within the program. Be careful not to overlap your
data. You may want leave additional registers/bits unused to allow for future
expansion in the program.
