226 Setting Up the DH+ Network
Typical DH+ Network
Configuration 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 processor
on the DH
+ network if the 1785-KA5 card is used with a PLC-5 processor.
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 below.
