Allen-Bradley SLC 500

C–4 Setting Up the DH+ Network
Publication 1747-6.2
The following figure illustrates a possible configuration for the SLC
5/04 processor on a DH+ network. You can also use an SLC 500,
SLC 5/01, SLC 5/02, SLC 5/03, or SLC 5/05 processor in place of
the SLC 5/04 on the DH+ network if the 1785-KA5 card is used with
a PLC-5.
IBM-PC, XT, or compatible with
1784-KT, 1784-KTX, or 1784-KTXD
APS
The PLC-5 and
1785-KA5 are
daisy chained
together.

The DH+ protocol uses factory set timeouts to restart token-passing
communication if the token is lost because of a defective node.
Other devices that use the DH+ network include those in the table
