IMPORTANT
Protocol (CSP), such as SLC 5/05 processors, PLC-5
processors, PLC-5 Ethernet sidecars (1785-ENET),
and RSLinx software, can use SLC 5/05 passthru.
Passthru does not work with Ethernet devices
supporting only EtherNet/IP protocol.

Passthru
RSLinx Classic, version 2.42 and below, only supports DF1 Full-duplex to
Ethernet, DF1 Half-duplex Master to Ethernet, DH-485 to Ethernet,
Ethernet to DF1 Full-duplex, and Ethernet to DH-485 passthru. RSLinx
Classic, version 2.43 supports all modes of channel-to-channel passthru
described below, except when channel 0 control line handshaking is enabled.
RSLinx Classic, version 2.50 and higher supports all modes of
channel-to-channel passthru as described below.
When channel 0 is configured for DF1 Full-duplex and S:34/5=1, the SLC
5/05 passthru processor can be used by RSLinx to go online through channel
0 to the channel 1 Ethernet network. Each Ethernet device that RSLinx
browses uses up an outgoing SLC 5/05 connection. See Table 12.3 to
determine how many available outgoing connections the SLC 5/05 has
available. The RSLinx RS-232 DF1 driver is used, with Device configured for
either 1770-KF3/1747-KE, which allows browsing of Ethernet devices from a
block of entries within the range of 1 to 31 in the Passthru Routing Table, or
for 1770-KF2/1785-KE, which allows browsing of Ethernet devices from a
block of entries within the range of 1 to 77 octal (1 to 63 decimal). The size of
the block of entries must not exceed the number of available outgoing
connections. The passthru processor will show up on the RSWho browse at
node 0. You should configure the properties of the DF1 network within
RSWho to browse the specific range of addresses that are being used in the
passthru routing table.
When channel 0 is configured for DF1 Half-duplex Master and S:34/5=1, the
SLC 5/05 passthru processor can be used by RSLinx to go online through
channel 0 to the channel 1 Ethernet network. The RSLinx DF1 Slave driver is
used. The SLC 5/05 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 a block of entries within the range of 129 to 254 (the
valid 5/05 passthru range of addresses, which is 128 plus the Passthru Routing
Table entry numbers of 1 to 126). The size of the block of entries must not
