Ethernet/IP Configuration File Format
The AN-X3-GENI supports scheduled connections with a ControlLogix processor over Ethernet.
The AN-X3-GENI behaves like a 17-slot ControlLogix rack with an ENBT/A module in slot 16
and generic modules in slots 0 to 15.
A ControlLogix processor can open a scheduled connection to each of these 16 generic modules.
Each scheduled connection consists of up to 248 words of output data from the ControlLogix
processor to the AN-X and up to 250 word of input data from the AN-X to the ControlLogix
processor.
Each connection can have a different RPI, up to 750 ms.
In general, keep the number of connections small. There is significant overhead in opening and
maintaining each connection.
You map the inputs and outputs for the Genius blocks to these scheduled connections. AN-X can
create the mappings automatically or you can create a mapping configuration manually.
You can let AN-X create a mapping file automatically, then edit the file to better suit your
application. For example, in order to make the most efficient use of the available Ethernet
bandwidth, you can organize the data so that items that must update quickly are mapped to
connections with short RPIs and items that are less time critical are mapped to connections with
longer RPIs.
In addition, the AN-X module has diagnostic data that can be mapped to ControlLogix scheduled
input data.
Mapping I/O Data
You map Genius input and output data to the ControlLogix scheduled data by creating a text file
that defines the mappings and sending the file to the AN-X.
The file contains sections for each scheduled connection. Within each scheduled connection are
the definitions for the input and output data for that connection. These definitions refer to the
Genius module where the data is to be found.
When you create a mapping for a Genius module, all the input or output data for the module is
mapped; you cannot map individual registers.
The file also contains options that apply to the whole configuration.
AN-X automatically creates mappings when you autoconfigure. See page 22 for details.
