it to be inoperable, it can no longer be a Duplex System and therefore automati-
cally changes to a Simplex System, with only the active CPU controlling the sys-
tem.
If there is an error that causes the active CPU to fail, the system again automati-
cally changes to a Simplex System, switching control to the operable CPU (the
standby CPU). For example, the switches on the front panel of the Duplex Unit
indicate that the right CPU is active and controlling the I/O Units in a Duplex Sys-
tem. If the active CPU fails, the system changes from a Duplex System to a Sim-
plex System and the operable standby CPU (in this example, the left CPU) takes
over the system operation and becomes the active CPU. The change from Du-
plex to Simplex and from active CPU to standby CPU takes place regardless of
the settings on the front panel of the Duplex Unit.
If you are using a Duplex System but want to use only one CPU to write a pro-
gram to the memory of the CPU or test the program in the CPU, switch the Du-
plex System to a Simplex System.
The flow chart below illustrates how the Duplex System can be changed to Sim-
plex operation. The switches referred to in the flow chart are on the front panel of
the Duplex Unit. Assume that there is a Programming Console already mounted
to the active CPU.
