A-B 9900-HMS-AIB Human Machine Interface Module

A-B 9900-HMS-AIB Human Machine Interface Module

The A-B 9900-HMS-AIB is not a true Allen-Bradley (Rockwell) HMI panel, but an HMS Networks Anybus industrial communication / interface module. It is used as a protocol gateway or interface module to connect different industrial networks (for example PLC ↔ fieldbus / Ethernet systems).

In practice, it is often mistakenly listed as an “HMI module”, but its correct function is industrial communication interface / gateway module, not a touchscreen or operator panel.
