Remote I/O Scanner controls
switching between dual
busses.
No Yes/No. If Yes, select Yes for
BSM Present (below).
BSM Present * BSM Controller set to YES. No Yes/No. If yes, Timeout Sec. is
configurable.
Timeout Sec. * Redundancy output time-
out, seconds. (Ignored if
BSM Present is NO)

ent is YES.
CFG Protect Configuration Protected None Yes/No
Redundancy * CPU Redundancy No redun-
dancy
No redundancy, Hot Standby,
or Duplex redundancy. Duplex
Redundancy cannot be used if
there are any analog modules in
the remote drop. Use only in dis-
crete–only remote drops.
Duplex Def * If CPU Redundancy is con-
figured for Duplex, this is
the default output state.
