Ladder logic

Ladder logic is a philosophy of drawing electrical logic schematics. It is now a graphical language very popular for programming.Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them.

S7-PLC SIMULATOR With Authorization Key

S7-PLCSIM, the Software for Simulating S7 CPUs

SIMATIC®, SIMATIC HMI®, and SIMATIC NET® are registered trademarks of Siemens AG. Third parties using any other names in this document which refer to trademarks for their own purposes might infringe upon the rights of the trademarks owners

S7-PLCSIM V 5.3 + SP1

S7-PLCSIM V5.3 + SP1 offers the following new features with this release:

1. Support of F-System peripheral I/O variables with color indication in view objects
2. Support of CPU 317-T hardware configurations with limited support of instructions
3. Support of hardware configurations with CiR (Configuration in RUN) objects
4. Ability to support STEP 7 projects containing configurations with more than one PROFIBUS line In addition, the data formats String and DT (Date and Time) are no longer available in view objects for peripheral I/O variables.

To be able to work with STEP 7 Professional in MS Windows 2000/2003/XP, you must have logged on at least as the user (not as a guest). You must possess administrator's rights for installing the STEP 7 software and also for setting up modules using the "Setting the PG/PC Interface" application. You need to possess administrator's rights to use S7 GRAPH. When using optional packages please observe the rights required by the respective optional packages.

If projects are saved on NTFS drives, the users must be granted full access here. This also applies to the folders with the HSP updates (default: C:/HWUPDATES). Access within S7PROJ is automatically granted to all users.

Switching between Real and Simulated CPUs

You can switch simulation on or off from the SIMATIC Manager or from STEP 7 Lite. To avoid confusion between real and simulated CPUs when using STEP 7 tools, you can only be in one mode or the other. You can think of this as switching from the "real" world to the "simulated" world. This switch is carried out at the MPI network communication level, so the real MPI network is effectively replaced with a virtual network on which only one simulated CPU is visible (in the Accessible Nodes window, for example). Conversely, when real CPUs are visible, the simulated CPU cannot be seen. STEP 7 or STEP 7 Lite will ask you to close any connections to one type of CPU before you are allowed to switch to the other type. For more information, see the S7-PLCSIM online help or electronic manual.

To switch simulation on or off from the SIMATIC Manager, use one of these methods:

1. Select the menu command Options > Simulate Modules
2. Click the toolbar button for S7-PLCSIM

What You Can Expect to Do with S7-PLCSIM

S7-PLCSIM allows you to load and debug an S7 program without a PLC, using the tools in the STEP 7 Standard software package and the S7-PLCSIM interface. It is primarily useful for debugging logic. Timing differs significantly from real CPUs, so some hardware testing is still recommended for timing concerns. Inputs and outputs can be easily monitored and changed from the visual interface. This product allows you to debug one CPU at a time.

Not all features of S7 CPUs are supported, so some advanced features of special products may produce error messages when run with S7-PLCSIM. For a complete description of the differences, see the S7-PLCSIM online help or the electronic manual.

Fundamentals of PLC program SIMATIC S7-300

Programmable logic controllers (PLC in brief), are considered today as a principal item of automation. With these controllers, most diverse tasks of automation can be implemented depending on the definition of the problem.These documents give you an overview of the automation system SIMATIC S7-300 and the appropriate programming software STEP 7.

FUNCTION AND DESIGN OF A PLC
The controller has the task of leading single operations of a machine or a machine plant that depend on
sensor signals after a given function execution.

TYPES OF SIGNALS IN CONTROL SYSTEM TECHNOLOGY
The electrical signals which are applied at the inputs and outputs can be, in principle, divided into two
different groups:

PLC - Programmable Logic Controller

Programmable Logic Controllers (PLCs), also referred to as
programmable controllers, are in the computer family. They are
used in commercial and industrial applications. A PLC monitors
inputs, makes decisions based on its program, and controls
outputs to automate a process or machine
. This course is meant
to supply you with basic information on the functions and
configurations of PLCs.

Programmable Controllers Theory And Implementation

Since the first edition of this book in 1988, the capabilities of programmable
logic controllers have grown by leaps and bounds. Likewise, the applications
of PLCs have grown with them. In fact, in todayís increasingly computer-
controlled environment, it is almost impossible to find a technical industry
that does not use programmable controllers in one form or another. To
respond to these phenomenal changes, we introduce the second edition of
Programmable Controllers: Theory and Implementation.

This second edition, like the first, provides a comprehensive theoretical, yet
practical, look at all aspects of PLCs and their associated devices and systems.
However, this version goes one step further with new chapters on advanced
PLC topics, such as I/O bus networks, fuzzy logic, the IEC 1131-3 program-
ming standard, process control, and PID algorithms
. This new edition also
presents revised, up-to-date information about existing topics, with expanded
graphics and new, hands-on examples. Furthermore, the new layout of the
bookówith features like two-tone graphics, key terms lists, well-defined
headings and sections, callout icons, and a revised, expanded glossaryó
makes the information presented even easier to understand.

This new edition has been a labor-intensive learning experience for all those
involved. As with any task so large, we could never have done it alone.
Therefore, we would like to thank the following companies for their help in
bringing this book to press: Allen-Bradley CompanyóIndustrial Computer
Group, ASI-USA, B & R Industrial Automation, Bailey Controls Company,
DeviceNet Vendors Association, ExperTune Software, Fieldbus Foundation,
Hoffman Engineering Company, HoneywellóMicroSwitch Division,
LANcityóCable Modem Division of Bay Networks, Mitsubishi Electronics,
Omron Electronics, Phoenix Contact, PLC Direct, PMC/BETA LP, Profibus
Trade Organization, Schaevitz Engineering Company, Siemens Automation,
Square D Company, Thermometrics, and WAGO.


We hope that you will find this book to be a valuable learning and reference
tool. We have tried to present a variety of programmable control operations;
however, with the unlimited variations in control systems, we certainly have
not been able to provide an exhaustive list of PLC applications. Only you,
armed with the knowledge gained through this book, can explore the true
limits of programmable logic controllers.
