The LOGO! control relay is being used to an increasing extent in installation technology, and also for simple industrial applications. This is because this mini PLC permits simple implementation of control tasks along with flexible use.
This handbook has a practice-based structure, and is appropriate for trainees, pupils and students as well as technical employees and trainers. In addition to basic "operating instructions", an holistic approach is used to indicate the fundamental procedures when tackling control problems.
At the beginning, programming of the LOGO! control relay is explained by means of a "quick start" using both manual inputs and the LOGOlSoft Comfort software. Standard situations encountered in control technology are subsequently presented in numerous projects (e.g. interlocks, sequential circuits, safety regulations etc.). Selection of the hardware is considered along with development of the program. The enclosed CD includes a LOGO! demo version. Readers can thus understand the explanations in the book in parallel on a PC, and check using a simulation. The scope of explanations is extremely detailed in the first examples, but is then continuously reduced to the necessary amount. In the more complex tasks, both the processing of analog values and the connection of LOGO! over the AS-i and LIB bus systems are treated. The comprehensive possibilities offered by the LOGO! control relay are presented here in abbreviated form such that the interest of LOGO! beginners is also aroused. The following functions of LOGO! are only available with the LOGO! devices starting with release version 0BA6 and with LOGOlSoft Comfort starting with version 6:
Analog arithmetic operations (Chapter 7.5 Mathematical functions)
External text display LOGO! TD (Chapter 7.6 and Chapter 8)
Pulse width modulation (Chapter 7.7 PWM) All other contents of the book can also be programmed for LOGO! devices of earlier release versions.
The last two chapters of the book are provided for information purposes for the previous project tasks. Detailed reference is made there to control elements, sensors and LOGO! hardware. This part is rounded off by a list of all program commands for LOGO! The enclosed CD contains the following contents:
LOGO'.Soft Comfort configuring software (demo version)
LOGO! control programs for the application examples presented in this book
The LOGO! Manual in eight languages: Chinese, Dutch, English, French, German, Italian, Russian, Spanish, Turkish
A PDF of a brochure on micro automation and LOGO!
The contents of the book form a training arrangement which directs you toward planned actions in that the steps "Planning" (including documentation), "Implementation" (= programming) and "Checking" (e.g. by means of program simulation) are executed in each project task.
The authors hope you will be able to work successfully with this handbook, and are always grateful to hear your responses or suggestions for improvement.
