Data). Make sure the Incoming and Outgoing Data areas in the Indirect Data Map do not
overlap.
The Outgoing Data typically includes RMC status items that the PLC always needs to keep
track of, such as actual positions and status bits.
The Incoming Data consists of items that the PLC needs to write to in the RMC. This is
typically variables and possibly command registers.
Note:
The Incoming and Outgoing Data locations need not be the Indirect Data Map. However, the
Indirect Data Map is usually the best choice. Other options are the Variable Table and the
command area.
Setting Up the RMC for PROFINET
Do the following in RMCTools:
1. Set the RMC's Device Name
In the Project pane, expand the Modules folder, double-click the CPU module, and
choose PROFINET. Under PROFINET Device Name, enter the desired unique
device name that your IO controller will use to refer to this device:
2. Set the RMC's IP Address
With PROFINET you can set up the IP address either through RMCTools and instruct
the PLC to not change the IP address, or you can allow the IO controller to set the
IP address. If you are using Ethernet to connect RMCTools to the controller, then be
sure that the IO controller and RMCTools do not conflict on the IP address the
module will use.
3. Set Up the Indirect Data Map
Beginning at item 0 in the Indirect Data Map, choose the items for the Outgoing
Cyclic I/O Data.
At some location in the Indirect Data Map after the Outgoing Cyclic I/O Data area,
choose the items for the Incoming Cyclic I/O Data, that is, the items that will be
sent to the RMC from the PLC. If you are using another location for your Incoming
Data, such as the Variable Table or Command Area, you need not set up the
Indirect Data Map for the Incoming Data.
Example
If you have a 4-axis controller, you may wish to set up the Outgoing Data at the
beginning of the Indirect Data Map to include the Actual Position and the Status
Bits for each axis, in addition to information on Task 0, which perhaps runs your
user programs.
You may also wish to set the Incoming Data, starting at item 16 in the Indirect
Data Map, to go to 5 variables and some of the Axis 0 command registers.
You could then set up the beginning of the Indirect Data Map like this for the
Outgoing Data:
