14-6 SLC Passthru Communications
When channel 0 is configured for DF1 Full-duplex and S:34/5=1, the SLC 
5/03 passthru processor can be used by RSLinx to go online through channel 
0 to the channel 1 DH-485 network. The RSLinx RS-232 DF1 driver is used, 
with Device configured for 1770-KF3/1747-KE. Remember to set S:34/6=1 
if attempting to browse or go online with SLC 500 fixed, SLC 5/01, SLC 5/02, 
ControlLogix, FlexLogix, and/or CompactLogix controllers on DH-485. The 
passthru processor will show up on the RSWho browse at its DH-485 node 
address.
When channel 0 is configured for DF1 Half-duplex Master and S:34/5=1, the 
SLC 5/03 passthru processor can be used by RSLinx to go online through 
channel 0 to the channel 1 DH-485 network. The RSLinx DF1 Slave driver is 
used. The SLC 5/03 passthru processor channel 0 configuration must be set 
up in Standard Polling Mode, and the slave address of RSLinx must be 
included in the polling range. The DF1 Slave driver properties in RSWho must 
be modified to poll for the valid 5/03 DF1 Half-duplex Master passthru range 
of addresses, which is 128 to 159 (for DH-485 nodes 0 to 31). The S:34/6=1 
should be set if attempting to browse or go online with SLC 500 fixed, SLC 
5/01, SLC 5/02, ControlLogix, FlexLogix, or CompactLogix controllers on 
DH-485. The passthru processor will show up on the RSWho browse at 128 
plus its DH-485 node address.
When channel 0 is configured for DH-485 and S:34/0=0, the SLC 5/03 
passthru processor can be used by RSLinx to go online through channel 0 to 
the channel 1 DH-485 network, when the PC running RSLinx is directly 
connected to the channel 0 DH-485 network through a 1784-KTX(D), 
1784-PKTX(D), or 1784-PCMK card. When RSWho is browsing the SLC 
5/03 on DH-485 with S:34/0=0, then a ‘+’ sign will appear to the left of the 
SLC 5/03 icon. Clicking on the ‘+’ sign will expose a DH-485 network 
underneath the SLC 5/03 icon. Clicking on the ‘+’ sign to the left of the 
DH-485 network will result in RSWho browsing for nodes 0 to 31 on the 
DH-485 network. You should configure the properties of the DH-485 
network within RSWho to browse the specific range of the addresses that are 
being used on the DH-485 network.
When channel 0 is configured for either DF1 Full-duplex, DF1 Half-duplex 
Master, DF1 Radio Modem (with S:34/5=1), or DH-485 (with S:34/0=0), the 
SLC 5/03 passthru processor can be used by RSLinx to go online through 
channel 1 to the channel 0 DF1 or DH-485 network, as long as the PC 
running RSLinx is directly connected to the DH-485 network through a 
1784-KTX(D), 1784-PKTX(D), or 1784-PCMK card. When RSWho is 
browsing the SLC 5/03 on DH-485, and channel 0 is either configured for 
IMPORTANT
In order to download a DH-485 PanelView standard 
terminal using RSLinx in this passthru setup, the DF1 
remote/local passthru bit must be cleared (S:34/6=0).
