 # **ethernetip‑rs**
 
 A Rust implementation of the EtherNet/IP™ protocol for symbolic tag access on Allen‑Bradley ControlLogix and CompactLogix PLCs.  
-The library provides an async API for reading and writing CIP tags, including typed accessors, arrays, fragmented reads, and multi‑tag operations, with correct EPATH encoding and optional slot routing.

 ## Overview
 
-`ethernetip-rs` implements both unconnected and connected CIP explicit messaging for
-Rockwell Logix controllers. The client supports standard SendRRData requests as well
-as Class‑3 connected messaging via Forward Open / Forward Close and SendUnitData.  
-It supports CompactLogix (no routing) and ControlLogix (CPU in a chassis slot).
