Important: If a fault occurs in a control coprocessor that is connected to
certain PLC-5 programmable controllers via the side connector, the
programmable controller may be unable to clear the major fault word
without first resetting the control coprocessor. In extreme cases, you may
need to separate the control coprocessor from the programmable controller.
The programmable controllers on which this may be necessary are:
PLC-5/60 (series B revision B)
PLC-5/40 (series B revision B)
PLC-5/30 (series A revision B)
PLC-5/20 (series A revision A)
PLC-5/11 (series A revision A)
Standalone Mode
In standalone mode, you do not connect the control coprocessor directly to
the PLC programmable controller. The control coprocessor can reside in
the same chassis as the programmable controller or in a remote chassis.
