Channel Configuration
(SLC 5/03 and 5/04 processors only)
The SLC 5/03 and SLC 5/04 processors each have two communication channels.
•
Channel 0 (RS–232) — applies to SLC 5/03 and SLC 5/04 processors
Use this channel to connect the processor to a modem or other devices using DF1
(RS-232) communication protocol or to a DH-485 link. You can configure this
channel for DF1 full-duplex (point-to-point), DF1 half-duplex (slave) protocol, or
DH-485 (using a PIC converter or a null-modem cable for a direct connection to
PLC-500 A.I.) protocol.
•
Channel 1 (DH-485) — applies to SLC 5/03 processors only
Use this channel to connect the processor to a DH-485 network. This channel
operates similar to the DH-485 channel contained in the SLC 5/01 and SLC 5/02
processors. The valid node address range is 0 - 31 decimal.
•
Channel 1 (DH
++
) — applies to SLC 5/04 processors only
Use this channel to connect the processor to the DH
+
network. Support of up to 64
nodes is available using this protocol. The valid node address range is 0 - 77 octal.
