Diversification

The current climate of ever-intensifying
competition has created a large number of
different needs for manufacturing industries
around the world. To meet these needs,
OMRON has made further improvements to its
SYSMAC CS1 PLCs, which have been used
successfully in thousands of systems, to deliver
even greater performance. With an "H" for Hyper
Controller, the new PLCs boast the highest
standards in performance, functionality, and
expandability.

Programmable Controllers are
abbreviated as "PLC" in this catalog.
The term "personal computers" is
fully written out, and not abbreviated.

In order to create facilites that have the production capability
to withstand sudden changes in demand, or to create
machinery that is easily distinguished from that created by
market competitors, a top-speed controller that can deliver
the performance required to support these needs is
required. The SYSMAC CS1 PLCs have been equipped with
the highest I/O responsiveness and data control functionality
to significantly reduce processing time and to control
machinery movement with greater precision.

In order to allow easier development of complex programs,
in addition to an integrated Windows-based development
environment, the new PLCs are equipped with a variety of
instructions. Structured programming functionality has been
improved to allow programs to be reused with greater
efficiency and thereby reduce labor requirements and cut
costs.

The know-how that our customers have accumulated
through the years forms the core of their competitive
strength. At OMRON, we believe in enhancing this know­how to the utmost. The key to doing this is 100% upward
compatibility. CS1 PLCs allow existing Units and programs
to be used without any changes.

Unit Versions

Unit versions have been introduced to
control differences in functions featured
by CPU Units that are the result of
version upgrades.
The unit version is marked on the
nameplates of products subject to
version control, as shown in the

instructions (FAL/FALS). With the new
CS1, debugging is simple for
applications that display messages on a
PT or other display device based on the
error status of the CPU Unit.

OMRON FB Library

(Unit Ver. 3.0 or later)

The OMRON FB library provides
function blocks for setting SPs, reading
PVs, and reading/writing RUN/STOP
status and other Temperature Controller
parameters. The programmer simply
pastes function blocks from the OMRON
FB Library into the ladder program. The
desired functions can be utilized simply
by inputting the Temperature Controller
unit number and address.

What is the OMRON FB Library?

The OMRON FB Library is a set of functional objects for
ladder programming for OMRON CS/CJ-series PLCs. By
incorporating the OMRON function blocks provided by
OMRON into a ladder program, the program interface for
different control devices is easily completed. This reduces the
number of working hours required for program development
and, at the same time, improves product quality through
standardization.

The Structured Text (ST)
Language Enables Trigonometric
Functions and other Arithmetic
Processes

In addition to ladder programming,
function block logic can be written in ST,
which conforms to IEC61131-3. With ST,
arithmetic processing is also possible,
including processing of absolute values,
square roots, logarithms, and
trigonometric functions (SIN, COS, and
TAN). Processing difficult to achieve in
ladder programs becomes easy to write.
