Use the extended-local I/O cables. These cables have a single-end
connector on one end and a dual-end connector on the other. The
maximum cable length for an extended-local I/O system is 30.5 cable-m
(100 cable-ft). Connect extended-local I/O adapters by using any of these
cables (Table 2.B):
Table 2.B
Standard Extended-Local I/O Cables
Cable Length: Catalog Number:
1 m (3.3 ft) 1771-CX1
2 m (6.6 ft) 1771-CX2
5 m (16.5 ft) 1771-CX5
Important: You cannot connect or splice extended-local I/O cables to
form a custom cable length. For example, if you have a distance of four
meters between two extended-local I/O adapters or between a processor
and an extended-local I/O adapter, you cannot connect two 2-m cables
together. You would have to use the 5-m cable and have the extra meter
as slack.
You must set switches on the extended-local I/O adapter module. For
information, see its installation data, publication 1771-2.200.
