With existing Duplex CPU Systems (such as the CVM1D), it is necessary to
manually return the system to Duplex Mode after a CPU Unit error occurs dur-
ing operation in Duplex Mode and operation is switched to Simplex Mode.
With the CS1D Duplex System, operation is automatically returned to the orig-
inal Duplex Mode when the error that caused the switch to Simplex Mode is
cleared.
Unmanned duplex operation can be continued even when incidental errors
occur temporarily due to causes such as noise.
Although only a single CPU Unit is mounted, duplex Power Supply Units,
duplex Communications Units, and online Unit replacement are possible.
Power is always supplied in parallel from two Power Supply Units. Even if one
of the Power Supply Units breaks down, the other one continues providing
power automatically. Power Supply Unit models for AC power and DC power
are both available, and a combination of both types can be used. A Power
Supply Unit that malfunctions or for which a broken line occurs can be con-
firmed by means of flags in the AR Area. If a Power Supply Unit malfunctions,
it can be replaced online without turning OFF the power supply or stopping
operation.
Two Communications Units (see note) are connected by fiber-optic cable. If
one of the Units stops communicating, the other one continues communica-
tions.
CLK12-V1 (H-PCF Cable) and the CS1W-CLK52-V1 (GI Cable) Controller
Link Units.
As shown in the following diagram, two Controller Link Units are mounted in a
single network with identical unit numbers and node addresses. One of the
Controller Link Units is in standby mode.
When an error is detected at the active Controller Link Unit, the standby Con-
troller Link Unit switches to active operating status. This allows communica-
tions to continue without the node being disconnected.
Standby CPU Unit:
Remains on standby while
executing the program.
