15-6 Messaging Examples
Passthru Example: DH-485 to DF1
The following illustrates a SLC 5/03 processor as a passthru processor that
receives remote messages targeting the SLC 5/04 on the DF1 network. The
SLC 5/03 processor will forward remote messages received on the DH-485
network (channel 1) to the DF1 network (channel 0) as local messages. For
this example, the SLC 5/03’s configuration bits are set to the following values.
• DF1 Pass-Thru Enable bit (S2:34/5) is set
• DH-485 Pass-Thru Disable bit (S2:34/0) is set
The DF1 Pass-Thru Enable Bit (S2:34/5) enables messages to be passed to
and from the channel 0 DF1 network from and to the channel 1 DH-485
network. This bit must be set to enable DH-485-to-DF1 passthru.
