Features
When two Power Supply Units are mounted, the Backplane’s 5-VDC power is
supplied simultaneously from the two Power Supply Units.
If one of the Power Supply Units breaks down, its load will be picked up by the
other Power Supply Unit. Be sure that the current consumption of all of the Units
mounted in the Backplane can be supplied by either one of the Power Supply
Units. If one of the Power Supply Units breaks down and the capacity of the other
Unit is insufficient, the second Unit will overload and the system will shutdown.
The Power Supply Units’ error status is displayed on Rack’s I/O Control Unit or
I/O Interface Unit (ICjjj/IIjjj). The error status is also indicated in the
Power Supply Unit OFF/Error Flags in A397 and A398.
The performance of CVM1D CPU Units is comparable to that of the CVM1-CPU-
EV1, but as part of the conversion to duplex operation several instructions have
been removed and some Units have become incompatible.
• C2000-ID216 Interrupt Input Unit
• C500-ASC03 ASCII Unit
Refer to the CVM1D Operation Manual for more details on the following instruc-
tions.
• Immediate-refresh Variations
• Interrupt Control Instructions
• Memory Card instructions
Memory Cards can be installed and used in each CPU Unit, although the Card’s
program and data are not included in duplex synchronization.
Cyclic refreshing is the only method used to refresh the entire I/O area. The I/O
REFRESH instruction (IORF(184)) can be used to refresh specific ranges of I/O
words. Immediate refreshing cannot be used in duplex mode.
The precision of the TIM, TIMH(015), and TTIM(120) timers has decreased
slightly because of changes in the refreshing process. Refer to the CVM1D Op-
eration Manual for more details on the precision of timers.
(If the Unit is mounted, it will operate as a normal 8-point Input Unit.)
(Immediate-refreshing variations can be used in simplex mode, but they can
cause improper operation in duplex mode so they should not be used.)
