Passthru Example: DH-485 to DH-485
The following illustrates a SLC 5/03 processor as a passthru processor when
both channel’s networks are configured for DH-485. The SLC 5/03 processor
will forward remote messages received on the DH-485 network (channel 1) to
the DH-485 network (channel 0) as remote 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 clear
• DH-485 Pass-Thru Disable bit (S2:34/0) is clear
The DH-485 Pass-Thru Disabled Bit (S2:34/0) enables messages to be passed
to and from the channel 1 DH-485 network from and to the channel 1
DH-485 network. This bit must be cleared to enable DH-485-to-DH-485
passthru.
