Allen-Bradley

A vendor family for EtherNetIPDevice

Allen-Bradley is the PLC vendor family EtherNetIPDevice targets, not a separate driver class: the config’s device.manufacturer field names it, and the connection block points at the PLC. Other Allen-Bradley Logix-family PLCs may work through the same underlying protocol, though current hardware testing covers only the CompactLogix 5332E 1769-L32E.
