SYSMAC LINK Networks using optical fiber cable and equipped with a
back-up power supply and Power Supply Units have an automatic bypass
function. If a failure or error occurs in a node of the network, that node will be
bypassed, and the rest of the network will continue functioning.
In the example shown below, node 3 fails, but communications continue by
bypassing node 3. The abbreviations in the diagram below indicate the fol-
lowing OMRON products:
The following table shows which Auxiliary Power Supply Units can be used
with the SYSMAC LINK Units.
In an optical network, power supplied from the Power Supply Unit that is con-
nected to each node will have precedence over power supplied from the back-up
Power Supply Unit of the system. Be sure to turn on the Power Supply Units and
the PCs simultaneously, or turn on the Power Supply Units first and then turn on
the PCs. If the Power Supply Units are turned on or off, a transmission data error
will result.
