About the 1747 Port Splitters
The 1747 Port Splitters, catalog numbers 1747-DPS1 and 1747-DPS2, allow a single
RS-232/DF1 full-duplex communication port on a controller to be split (expanded)
into two ports for communication with two external devices simultaneously. Port
splitters are compatible with the following controllers:
• SLC 500
• PLC-5
• MicroLogix
• ControlLogix
• CompactLogix
• FlexLogix
Both port splitters require an external power source and use Allen-Bradley
programming cables.
1747-DPS1 Port Splitter Features
The 1747-DPS1 port splitter, when connected to a controller, provides one network
port for two-way communication between the controller and a local network.
The second port is respond only and can run a programming terminal or human
machine interface (HMI). Both the network port and respond-only Prog/HMI port
are DF1 full-duplex, 19.2 Kbps, 8 data bits, and 1 stop bit.
The 1747-DPS1 port splitter is not rated for Class I, Division 2 Group A, B, C, D
Hazardous Locations.
