Rockwell Automation 2706-LV2P_LV2R_LV4P_LV4R DL40 PLUS USER MANUAL - Manual (Page 137)

Installation and Wiring 9–8
Publication 2706-6.1
The Remote I/O connector on the back of the DL40 Plus connects
the DL40 Plus to the host PLC via the remote I/O link (Catalog No.
1746-RT29).
The Remote I/O link begins at the scanner module. The scanner
modules and programmable controllers impose physical and logical
limitations on the link. You must know these limitations to avoid
exceeding them.
To the rest of the system, the DL40 Plus looks like a Remote I/O
rack, and is addressed as such.
The maximum cable length (link distance) is limited by the baud rate
selected for the system:
10,000 feet (2,800m) for 57.6K baud
5,000 feet (1,400m) for 115.2K baud
2,500 feet (700m) for 230.4K baud
The actual connection is through a Catalog Number 1770–CD Serial
Data Link cable with a connector for the DL40 Plus.
Note: Use 150
Ω , 1 /
2
W. resistors to terminate links operating at 57.6
or 115.2K baud; use 82
Ω
, 1 /
2
W. resistors to terminate links operating
at 230.4K baud.
