Important Notes About I/O Bus Expansion Cables
1. The maximum number of cables that can be included in an I/O expansion system is
seven, and the total maximum cable length between the CPU baseplate and the last
expansion baseplate is 50 feet (15 meters). The total maximum cable length between
the CPU baseplate and the last remote baseplate is 700 feet (213 meters). Failure to
observe these maximum cable lengths could result in erratic operation of the PLC
system.
2. CPUs 350 – 364 support a maximum of seven I/O expansion cables. CPUs 331 – 341
support a maximum of four I/O expansion cables.
3. The 50 foot (15 meter) I/O bus expansion cable (IC693CBL302), which has a male
connector on each end, has the I/O bus terminating resistors built into the end
connector on the cable. If this cable is used, you would not install a separate terminator
block.
Caution
I/O Bus Expansion cables should NOT be connected or disconnected
with power applied to the I/O expansion baseplate(s). Unexpected
PLC operation may result.
Cable Application Suggestions
In general, it is advantageous to use standard, factory-built cables, where possible, to
save time and avoid wiring errors.
Using Standard Cables
For connecting between baseplates (either between a CPU and expansion baseplate,
between two expansion baseplates or between two remote baseplates) in the same
cabinet when a standard length (0.5, 1, 2, 8, or 15 meters) will fit the need.
As a Wye jumper for custom built point-to-point cables (IC693CBL300 is often used
for this). This combination saves time since a point-to-point cable can be built much
faster than a Wye cable. An example of this is shown in Figure 10-23.
Using Custom Built cables
When you need a cable length not available in a standard size.
When a cable must be routed through a conduit that is not large enough for a
standard cable’s connector to fit through.
