Based on the configuration described above for the ModDef section of the
module and the values specified for the offset parameters, below is the Modbus
addressing map for the module.
MVI Address 0x 1x 3x 4x Tag Address
0 10001 to 10016 WriteData[0]
1 10017 to 10032 WriteData[1]
9 10145 to 10160 WriteData[9]
10 10161 to 10176 30001 WriteData[10]
11 10177 to 10192 30002 WriteData[11]
100 11601 to 11616 30091 WriteData[100]
200 13201 to 13216 30191 WriteData[200]
500 18001 to 18016 30491 WriteData[500]
598 19569 to 19584 30489 WriteData[598]
599 19585 to 19600 30490 WriteData[599]
600 to 999 N/A N/A N/A N/A Reserved
1000 0001 to 0016 ReadData[0]
1001 0017 to 0032 ReadData[1]
1009 0145 to 0160 ReadData[9]
1010 0161 to 0176 40001 ReadData[10]
1011 0177 to 0192 40002 ReadData[11]
1050 0801 to 0816 40041 ReadData[50]
1100 1601 to 1616 40091 ReadData[100]
1200 3201 to 3216 40191 ReadData[200]
1500 8001 to 8016 40491 ReadData[500]
1598 9569 to 9584 40589 ReadData[598]
1599 9585 to 9600 40590 ReadData[599]
With the offset parameters listed above, the Modbus Master could read from coils
10001 to 10176 using the tags MCMR.DATA.W
RITE D ATA [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 MCMR.DATA.W
RITE D ATA [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 MCMR.DATA.R
EAD D ATA [0] TO
[9]. The Master could then write to registers using Modbus addresses 40001 to
40590, and this information would reside in addresses
MCMR.DATA.R
EAD D ATA [10] TO [599].
Note: The offset parameter only set 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 MCMR.DATA.R
EAD D ATA [10].
Likewise, a Write To bit address 0161 will also change to address
MCMR.DATA.R
EAD D ATA [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.
