PC Configuration
Unit Numbers
Note 1. When two or more PCs are linked, apply power to all of the PCs at once
or to PC #0 last.
2. When using a Link Adapter, one PC must be connected to connector
number 0 on the Link Adapter.
3. Once CPUs are connected to the Link Adapter and turned ON, unit num-
bers are automatically assigned to the CPUs by the Link Adapter. Do not
change the point of connection of any CPU after a unit number has been
assigned to it. If CPUs are connected to a connecter for a different unit
number, unpredictable errors will occur during operation.
When four PCs are linked, each are given a number from 0 through 3 de-
pending on which connector on the Link Adapter is used. PC #0 controls LR
data transfers between the PCs. The Programming Console is connected to
the Link Adapter and can program and monitor any of the four PCs.
