Maximum cycle time = Normal cycle time +
A is the time added when duplex Inner Boards are mounted. Refer to the
Inner Board Operation Manual for the value of A.
Unit versions are used to identify functional additions to CS1D CPU Units.
(Refer to information on unit versions at the front of this manual for details.)
Upward compatibility is provided for all functional additions to CS1D CPU
Units. Duplex CPU Unit operation is thus possible for CPU Units of different
unit versions as long as only the functions supported by both unit versions are
used.
Duplex CPU Unit operation is possible as long as the active CPU Unit does
not use any functions not supported by the standby CPU Unit.
Duplex CPU Unit operation is not possible if the unit version of the active CPU
Unit is earlier than that of the standby CPU Unit and the Active CPU Unit uses
functions not supported by the Standby CPU Unit. If this happens, a Duplex
Verification Error will occur and operation will be in Simplex Mode.
A31708 will turn ON to indicate a CPU Unit Version Verification Error as the
cause of the Duplex Verification Error. This error will be detected at the follow-
ing times.
