Processor Communication Options

The SLC 500 processors support several communication options. The
following sections describe the available physical connections and
protocol options used by the SLC 500 processors.
Physical Connection Options
Ethernet (10/100Base-T) channel offers:
• 10/100 Mbps communication rate.
• ISO/IEC 8802-3STD 802.3 (RJ45) connector for 10/100Base-T
media.
• TCP/IP communication protocol.
• built-in isolation.
Data Highway Plus (DH+) channel offers:
• communication rates of 57.6 Kbaud, 115.2 Kbaud, and 230.4
Kbaud.
• maximum network length of 3048 m (10,000 ft) at 57.6 Kbaud
• Belden 9463 (blue hose) cable connection between nodes (daisy
chain connection).
• built-in isolation.
DH-485 channel offers:
• configurable isolation via the 1747-AIC or 1761-NET-AIC
interfaces.
• maximum network length of 1219 m (4000 ft).
• RS-485 electrical specifications.
• Belden 9842 or Belden 3106A cable connection between nodes
(daisy-chain connection).
RS-232 channel offers:
• communication rates up to 19.2 Kbaud (38.4 Kbaud SLC 5/04
and SLC 5/05 processors).
• maximum distance between devices is 15.24 m (50 ft).
