# Allen-Bradley

A vendor family for [`EtherNetIPDevice`](https://dev.nominal.io/instro/library/protocols/ethernetip.md)

![Allen-Bradley](https://dev.nominal.io/instro/_images/AllenBradley.png)

Allen-Bradley is the PLC vendor family [`EtherNetIPDevice`](https://dev.nominal.io/instro/library/protocols/ethernetip.md) 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](https://dev.nominal.io/instro/library/protocols/ethernetip/CompactLogix.md) 5332E 1769-L32E.
