When the routing table is downloaded, RSLinx returns to the Browsing screen.
This completes the routing table creation process.
Configure the Controller Slot
The Controller Slot is the physical location of a ControlLogix controller in a
DH+ application. The default setting is slot 0. If necessary, use the Channel
Configuration tab to change the Controller Slot number.
Use RSLinx Software to Send
Control and Information
Protocol Messages The 1756-DHRIO and 1756-DHRIOXT modules cannot receive Control and
Information Protocol (CIP) messages on one of its DH+ channels to send the
messages as Programmable Controller Communication Command (PCCC)
messages out of its second DH+ channel.
RSLinx software uses the CIP protocol when it sends messages via Ethernet or
ControlNet networks. Therefore, it cannot route an RSWho message from an
1756-ENET module to one 1756-DHRIO or1756-DHRIOXT module, to
channel A of a second 1756-DHRIO or 1756-DHRIOXT module in a second
chassis, and out of channel B of the second 1756-DHRIO or1756-DHRIOXT
module (see the X in the following figure).
