16 16 Axis PCI SERCOS interface Card
Publication 1784-IN041A-EN-P – June 2003
Fiber Optic Transmission
The fiber optic transmitter for the SERCOS interface 16 Axis PCI card uses
a 650nm wavelength. This produces a visible light from the port and is a
determinant in factoring maximum cable lengths. The high light output lets
you use both plastic optical fiber (POF) and hard clad silica (HCS) cables.
The fiber optics used with the 1784-PM16SE card is rated Class 1 for IEC
Laser (LED) Safety Classification. Be aware that under certain conditions,
viewing the optical port may expose the eye to hazard. Under most viewing
conditions, there is no eye hazard.
IMPORTANT
Each additional SoftLogix controller requires additional
computer hardware resources that can impact
performance. Additional computer processor capabilities
or an increase in the motion Coarse Update Periods may
be required. See publication 1789-UM002 Using Multiple
SoftLogix Controllers
for more information.
IMPORTANT
Producing and consuming motion data between
SoftLogix Controllers is not recommended. This is due
to the asynchronous relationship of a 1784-PM16SE card
with other motion cards in your computer. For
applications that require tight coordination among
multiple motion cards, physically couple the feedback
from one common axis to each card.
ATTENTION
!
When viewed under some conditions, the optical port
may expose the eye beyond the maximum permissible
exposure recommended in ANSI Z136.2, 1997.
