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.
