Communication Ports
CN1 and CN2
The control network connects to one or two RJ45 connectors (CN1 and CN2)
depending on network option (single or redundant).
Use an RJ45 connector for IEEE802.3 (Ethernet) for connecting to a category 5
Shielded Twisted Pair cable (STP class 5).
Class 5, or higher, cable 10/100BaseT/TX max 100 m (110 yd). ABB recommends
the use of optical fiber in an industrial environment, for example 62.5/125
100BaseFX, max. distance 1500 m (1600 yd).
