Features
Features
The SYSMAC CVM1D Duplex System is a high-speed, highly reliable ladder-
program PC that can operate 24 hours/day.
The redundant CPU Units allow continuous, 24-hour/day PC operation. The
CVM1D-CPU21 CPU Unit was developed specifically for the duplex system and
based on the CVM1-CPU21-V2 CPU Unit, so the duplex CPU Unit inherits the
superior performance of the CVM1 and CV-series PCs.
The PC can operate in duplex mode or simplex mode depending on the setting
of the Duplex/Simplex Mode Switch on the front of the Duplex Unit.
Redundant Power Supply Units have been added to CPU Racks, Expansion
CPU Racks, and Expansion I/O Racks. The two Units supply power to the rack in
parallel. Even if one of the Power Supply Units breaks down, the PC can contin-
ue operating normally and the faulty Unit can be replaced without interruption.
Backplanes that accommodate two Power Supply Units must be used for the
Expansion CPU Racks and Expansion I/O Racks in order to take advantage of
the redundant power supply function.
When an error occurs in an I/O Unit, the faulty Unit can be replaced without turn-
ing off the power to the whole system. Use the duplex system’s
CVM1-PRS21-EV1 Programming Console to replace an I/O Unit online.
C500 I/O Units and Special I/O Units as well as CV-series CPU Bus Units can be
used with CVM1D PCs.
A CVM1D Duplex System can be assembled with redundant CPU Units and
Power Supply Units to allow continuous operation.
A CVM1D can be configured to run in duplex mode with two CPU Units operating
in parallel or in simplex mode with one CPU Unit operating independently.
• Duplex (DPL) System:
• Simplex (SPL) System:
A CVM1D CPU Backplane is equipped with two CPU Units, a Duplex Unit, and
two Power Supply Units.
Both CPU Units and Power Supply Units are redundant.
One CPU Unit is used, but Power Supply Units are redundant.
