Connecting the I/O Link

To connect the extended-local I/O link:
make sure you have the correct cable length
make the extended-local I/O connection
Make Sure you have the Correct Cable Length
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 using any of these
cables (Table 9.A):
Table 9.A
Standard ExtendedĆLocal I/O Cables
Cable Length: Catalog Number:
1 m (3.3 ft) 1771ĆCX1
2 m (6.6 ft) 1771ĆCX2
5 m (16.5 ft) 1771ĆCX5
0.15 m (0.5 ft) 5110ĆMXC4
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.
If you do need a custom cable, these are available (Table 9.B):
