We are working with Allen Bradley PLCs, MicroLogix and ControlLogix models. The way to configure datapoints for MicroLogix PLC is clear. For the ControlLogix datapoints too, is an easy way and they are working correctly. The problem I've got is that our ControlLogix models have the possibility to extend the CPU data through input expansion cards or a similar ones.
In our case, we have the format of this tags in the PLC program are shown below:
Local:3:I.CH0DATA
Local:6:I.Data.5
Local:9:I.Data.9
Remoto:5:I.Data.24
Has WinCCOA the possibility to read data from this type of expansion cards? Which is the correct format in the field PLC_TAG, configured in the address? At the EIP driver have we got to configure an specific connection driver? We are very interested in read this kind of datapoint directly through EIP driver instead of read this data through the RSLinx, OPC gateway.
ControlLogix datapoints are read correctly but we are not able to read this special king of datapoints.
Any idea?

I have received the following answer from the developer:
Unfortunately, remote I/O routing is not currently implemented in this driver.
Perhaps these could be set up as Aliases in the PLC, but we have not done any testing of this sort of configuration.
