CS1D Duplex System Overview and Features
CS1D Duplex System Features
Note Operation will be taken over by the standby CPU Unit for any of the following
Two CPU Units and one Duplex Unit are mounted.
The two CPU Units always run the same user's program. One of them exe-
cutes the system I/O while the other remains on standby. If an error (see note)
occurs in the controlling CPU Unit (called the active CPU Unit), control is
switched to the other CPU Unit (called the standby CPU Unit), and operation
continues. (The system will stop, however, if the same error occurs in the
standby CPU Unit, or if another operation switching error or a fatal error
occurs.)
operation switching errors: CPU error, memory error, cycle time overrun error,
program error, FALS error, or fatal Inner Board error. (A fatal Inner Board error
applies only to Process-control CPU Units.)
With the hot standby method, the standby CPU Unit operates with the same
status as the active CPU Unit. Using this method provides the following bene-
fits.
