Omron Enhances PLC Performance and
Flexibility with CJ2M Series
FEBRUARY 20, 2010
(ASIA PACIFIC) - A versatile and cost-effective choice for
applications of low to medium complexity, the new CJ2M range of
PLCs from Omron has been specifically
designed to help users meet demands for increasing intelligence
and flexibility in control systems, while at the same
maintaining competitive pricing. The new CJ2M PLCs
complement the recently introduced CJ2H models, which offer
similar benefits in high-end applications.
Based on the proven technology of Omron’s CJ1 Series PLCs, which are in
use in tens of thousands of applications around the world, the
new CJ2M products offer a wider choice of CPUs, faster operating
speed, more memory and enhanced communications facilities,
including optional integrated Ethernet support.
Two more important benefits of
CJ2M PLCs, which they share with their CJ2H high-end
counterparts, are consistent architecture across the whole
series, which means that up- or down-scaling applications is fast
and easy, and upgraded support for function blocks. These allow
blocks of program to be developed for commonly used functions;
the blocks can then be re-used as required, either in the same
project or in new projects, leading to big reductions in the
time needed for programming and testing.
CPUs in the CJ2M Series are
available to suit any task, starting at 5 Ksteps program
capacity plus 64 Kwords memory. The CJ2M models offer up to 60
Ksteps and 160 Kwords, while the CJ2H extends this to 400 Ksteps
and 832 Kwords. All versions have a USB port to provide
convenient access for programming, maintenance and
troubleshooting, and all are offered with a choice of either an
integrated Ethernet port with Ethernet/IP Data Link function or
an RS-232C serial interface. To provide even greater
versatility, the Ethernet models have a slot that can optionally
be fitted with an RS-232C/422/485 port.
To complement its CJ2 PLCs, Omron has introduced new high-speed
I/O units. These include analogue input modules with a
conversion time of just 20µs, and fast digital I/O, the data
from which can be instantly accessed using special program
instructions. CJ2 PLCs can also be connected to CJ1 Series I/O units,
making it easy and inexpensive for users to upgrade or expand
existing installations.
