Cable length
I/O Link Interface cables are to be no longer than 10 m (33 feet) in total length and are not to leave the
cabinet or cabinet complex.
Redundant cables
Two cables are required because the I/O Link Interface is redundant for reliability. One cable is
designated Link A and the other Link B.
No cable termination
The I/O Link Interface cabling does not involve external terminators and therefore an empty I/O Link
Interface connector on the backpanel is an acceptable situation.
CAUTION
The High-Performance Process Manager accommodates four types of card files. Use caution
when connecting the I/O Link Interface cables because of the differences between the card
files. All card files have two I/O Link Interface receptacles marked
LINKA
and
LINKB
.
