6 Communication
For details on using the Indirect Data Map for PROFIBUS, see the PROFIBUS topic, and then
choose a PROFIBUS mode topic.
The address examples in this topic are given in Allen-Bradley DF1 format. The Indirect Data
Map can be used for all protocol address types supported by the RMC. See the Register Maps
for addresses for other protocols.
Using the Indirect Data Map
The Indirect Data registers can be mapped to any registers in the RMC. Thereby, the
values from the mapped registers in the RMC can be read from and written to by writing
to and reading from the Indirect Data registers.
To set up the Indirect Data Map:
1. Open the Indirect Data Map Editor.
2. In the Map To column of each Indirect Data Map entry, enter the RMC register you
want to map. You can map as many of the Indirect Data Map entries as you would
like.
3. Click the Download button to download the changes to the RMC.
4. Now, with your PLC or other host controller, you can read or write your data directly
from the Indirect Data registers. Notice that if a mapped register is read-only, you
cannot write to it.
Note:
Do not write to registers in the Indirect Data Map that have not been mapped. This may
unnecessarily fill up the Event Log with errors.
Example
The user would like to put some of the RMC70 registers in the Indirect Data Map so
that the communications can be more efficient. The user decides to put the following
registers in the Indirect Data Map:
• Axis 0 Status Bits
• Axis 0 Error Bits
• Axis 0 Actual Position
• Axis 0 Actual Pressure
• Axis 1 Status Bits
• Axis 1 Error Bits
• Axis 1 Actual Position
• Axis 1 Actual Pressure
The user then sets up the Indirect Data Map as shown below:
