OVERVIEW OF A LC700 SYSTEM
The LC700 is a powerful device added to Smar’s line of products. LC700 is a compact programable
logic controller, fully-modular to adapt into a large variety of applications. This innovative product works
with an advanced CPU suppling a higher performance. Fieldbus modules are available making the
LC700 ready to interact with Fieldbus signals from different devices.

Note
Check with the factory for availability of DN-700 and DP-700 modules.
Moreover, programming is turned into a simple configuration due to an easy to use Windows based
software. Configuration is compatible with IEC-61131-3 Ladder Logic standards. In addition, the
software makes it possible to segment the solution creating simple or complex logic ladder networks.
Creating Boolean functions as well as assign I/O and auxiliary signals to the logic is as easy as a couple
of mouse clicks! Memory allocation and default names are automatically created! No more extra thinking
in arranging memory space! Let the computer work for you!
The LC700 brings speed, modularity and fieldbus interface combined with reliability and low cost for the
plant.
Its modular design gives tremendous flexibility to the application. The I/O modules can be selected from
a broad range of different signal types to perfectly fit the plant necessities.
The LC700 is able to deal with a total of 2000(*) discrete points, 1024 analog variables and carries a
large list of function blocks from the most standard instructions to more sophisticated ones for process
control.
The LC700 processing power, modularity and reliability makes it an intelligent choice for a wide range of
applications in Process Control and Automation .
