Redundancy System Solutions
JUNE 15, 2004 (ASIA PACIFIC) -
Omron Asia Pacific is proud to present the new Redundancy Systems CS1D-S Series, an addition to the current CS1D Duplex System.
For critical applications which require zero downtime, Omron’s
CS1D Redundancy System will be the right choice as it provides
users with an attractive standby functionality. With "hot swap"
capability, it enables continuous process control without
interrupting control operation, thus providing a reliable
solution for critical applications.
In a redundancy system, two CPUs (Central Processing Units) will
run continuously with one in active mode and the other in
standby mode. A duplex unit will monitor the status of the
active unit. In the event of failure, the duplex unit will
switch control over to the standby CPU unit automatically. Thus,
the failed CPU can be replaced while the process is still
running.
Besides CPU redundancy, power supply redundancy is also
supported. Users are able to mount two power supply units on
each rack. This helps ensure a constant power source is being
supplied to the system at all times, even if one of the power
supply units (or its power source) should fail. The CS1D also
supports hot-swapping of faulty I/O (Input/ Output), intelligent
and I/O cards, which can be replaced while the system is powered
and running.
In addition, the CS1D series also
comes with Process CPU which consists of a delicate processor
for process control and supports up to 500 Function Blocks with
delicate function for process control. Sequence Table and Step
Ladder can be created for process sequence. CS1D series also
supports Hot Start for process control.
Redundancy in communications is available by installing dual
Ethernet (CS1D-ETN21D) or Controller Link (CS1W-CLK52-V1) units.
The Controller Link units can be configured to be in active or
standby mode, and the physical network achieves redundancy
through fiber optic with token ring. As for the Ethernet
communication, primary and secondary networks can be configured
for redundancy.
Should communication of the active unit fail, both
above-mentioned units (Ethernet and Controller Link) are able to
switchover automatically to the standby unit. Such features can
be enabled by simple configuration.
Besides that, the CS1D Series
Programmable Controller is compatible with a wide variety of
communication platforms such as FL-Net, Profibus-DP, DeviceNet,
CompoNet and other open networks. On-site monitoring, email data
monitoring, alarm alert and preventive maintenance features can
also be supported.
Omron’s new CS1D-S series uses a single CPU (i.e. Simplex
system). These series inherited the features of the CS1D-Duplex,
except for CPU redundancy, in addressing non-critical control
applications which demand system availability on redundant power
supply and network connectivity.
