Allen-Bradley ControlLogix Ethernet Driver Help
Default Data Type in the server, the driver will read "MyTag" from the controller and determine that it is a REAL in the response. Thus, it will provide the client item a data type of Float.
Note 2: Since the majority of I/O module tags are not bit-within-Word/DWord tags, it is advised that the Default Type be set to the majority data type as observed in the .ACD project. For example, if 75% of alias I/O module tags are INT tags, set the Default Type to INT.
Enable Performance Statistics: The Allen-Bradley ControlLogix Ethernet Driver has the ability to gather communication statistics to help determine the driver's performance. When checked, this option will be enabled. The driver will then track the number and types of Client/Server Tag updates. On restart of the server application, the results will be displayed in the server's Event Log. The default setting is No.
Note: Once a project configuration is designed for optimal performance, it is recommended that users disable Performance Statistics. Furthermore, since the statistics are outputted to the Event Log on shutdown, the server will need to be re-launched to view the results.

Default Data Type Conditions Client/Server Tags are assigned the default data type when any of the following conditions occur:
A Dynamic Tag is created in the client with Native as its assigned data type.
A Static Tag is created in the server with Default as its assigned data type.
In offline automatic tag generation, when an unknown data type is encountered in the L5K/L5X file for
UDT members and Alias Tags.
In offline automatic tag generation, when an alias of the following type is encountered in the L5K/L5X:
Alias of an alias.
Alias of non bit-within-Word/DWord I/O module tag. For example, if tag "AliasTag" references I/O module
tag "Local:5:C.ProgToFaultEn" @ BOOL, the data type for "AliasTag" cannot be resolved and thus this Default Type is assigned to it. On the other hand, if "Alias Tag" references I/O module tag "Local:5:C.Ch0Config.RangeType.0" @ BOOL, the data type can be resolved because of the . (dot) BIT that defines it as a bit-within-Word/DWord. Aliases of bit-within-Word/DWord I/O module tags are automatically assigned the Boolean data type.
