CS1W-LCB01 / LCB05

Increasing amounts of information, standardization, and open standards form the basis for achieving hardware and networking capabilities for process control.
A wide range of software that can be easily used by design, development, and maintenance personnel makes operating and maintaining the system far easier.

Systems are large, meaning high initial costs.

The over-spec nature of a distributed control system (DCS) increased costs.
PLCs, however, could not provide the required process control capabilities, and signal conversion with isolators and other devices was required for I/O.
It was just not possible to achieve the ideal system for a specific application.

Down-sizing
Cut costs, Save space, Reduce labor

PLCs provide the some of the functions and performance of DCS while also providing the advanced features of PLCs: Open specs, easy maintenance, and cost performance.
A wide range of Isolated-type Analog Units helps to save space and greatly reduces system costs.

Running costs are high because maintenance and modifications require specialists.

The manufacturer must be relied upon for everything from system construction to maintenance.
Even simple changes to parameters cannot be performed in-house.
And, it's nearly impossible to use generalpurpose devices and software (such as HMI devices or Windows-based software) when modifying the system.

Easy Engineering
Engineering is simple when you can program with function blocks.

Paste function blocks in a window just like you were creating a flow sheet, and then connect the blocks with the mouse to graphically program a wide range of process control.
And with a PLC, it's easy to incorporate general-purpose HMI devices and software (such as touch panels and SCADA software).

Increase the reliability of the facilities and devices with a Duplex PLC-based Process Control System.

If an error occurs in the active CPU Unit, the standby CPU Unit takes over in an instant (using the hot standby method) so that system operation continues essentially unaffected.
Other duplex variations are also possible.
For example, instead of duplexing the CPU Unit, Power Supply Unit, and Controller Link Unit, a system can be constructed with a Single-CPU Unit and only a duplex Power Supply Unit or only a duplex Controller Link Unit.

A duplex system means rapid recovery for errors.

Replace Units with power supplied or even while the system is running, including CPU Units (Duplex-CPU system), Power Supply Units, Communications Units, Basic I/O Units, and Special I/O Units.

Excessive installation space is required.

When using more than one controller for multi-loop control, the control panel is just too big.
And specification changes required altering the control panel, making changes difficult.

Down-sizing
Consolidate the functions of many controllers

Programming is as simple as combining the function blocks required by the application.
To increase the number of controlled loops, just add them to the program.
HMI windows can also be created easily using a wide range of utility software.

Programming communications with the controllers is extremely difficult.

Communications must be programmed to input data to the PLC.
And communications time can restrict control performance.
The more controllers that are used, the more difficult maintenance becomes.

Easy Engineering
Advanced controller functions are built into the CS1 PLCs. No programming is required for communications.

The Loop Control Boards and Units were designed for the CS1 PLCs and require no communications programming.
High-speed, flexible data links can be created with the PLC to increase control performance.
