The Allen Bradley ControlLogix driver is used for all Logix Family of processors.
AB PLC Firmware versions after 15 require the driver to use Protocol Option of Symbolic to avoid issues caused by the remapping of memory types in the PLC.
There are some PLC models that do not work with the drivers no matter the settings.
The PLCs that do not work are the 5380/5580/GuardLogix. The 5375 and 5575 are the last version compatible with the included drivers.
For newer unsupported versions, it would be necessary to use a third party OPC DA server with support for those drives.
InteractX can then use that third party OPC DA Server as a "Data Source" instead of the build in Com server.
We will attempt to keep this list updated as the models continue to change.
