Delta RMC151 - Manual (Page 590)

RMC70/150 and RMCTools User Manual
shows the derived variables created for the example device in the steps above:
The RMC150E_rev2_deva_IN structure represents data produced by the RMC, starting
with the Sync Register followed by the Outgoing Cyclic I/O Data in the RMC, which in this
example is %MD42.0-9 from the Indirect Data Map. The RMC150E_rev2_deva_OUT
structure represents data consumed by the RMC, starting with the Sync Register followed
by the Incoming Cyclic I/O Data in the RMC, which in this example is %MD42.12-22 in
the Indirect Data Map.
Performing Communications
Once the EtherNet/IP connection is configured and applied to the PLC, the
communications will automatically start, assuming the PLC and RMC are both on a
properly set up Ethernet network. Notice that the Omron will communicate even when it
is in Program mode.
Reading Data from the RMC
This data will automatically update each Requested packet interval, and you can use the
data as you wish. You cannot write to the Input Data. The Input Data will contain the
Indirect Data from the RMC. However, if you selected to use the Sync Register, the first
item in the Input Data array will be the SyncIn value, followed by the Indirect Data from
the RMC.
The SyncIn is used only for synchronizing commands with the logic, as explained below.
The SyncIn and SyncOut registers are only visible in the PLC. They are not visible in
RMCTools.
