Hello everyone,
With this course from one collegue to another about Siemens SIMATIC both Hardware And Software Side you will able to get information and for your future career, you will gain more experience during your business life. So from this point of view if you are interested with industrial automation sector, specially automation and control area, Simatic is one of the most commonly used product family in industry.
From beginning step by step this the second course offers you complete walktrough of a serie. And it will continiue with "Siemens Simatic Manager S7 System and Programming" as 1-2-3.
During this course you will become familiar with the fundemental principle of a logic controller, concept of modular SIMATIC system, basic operating procedures of Simatic Manager.
You will be familiar with Registers and Memory areas of S7-CPU, status word structure, instructions in STL, extended mathematical functions with real variables, direct and indirect adressing.
You will know how to work with adress registers for area-internal or area-crossing indirect adressing. And you will see any, pointer data types, elementary and complex data types, such as arrays, structures, user defined data types with datablocks.
You will get information related with structured programming, function and function blocks, object oriented programming with multi instance data blocks of function blocks.
During this training you will examine standart library, overview of SFC, SFB system functions, and other libraries such as S5 to S7 converting blocks, TI to S7 converting blocks, communication blocks, pid control blocks and so on.
After this training you can handle with system errors, asynchronous faults, use organisation blocks for programming error, access error.
You will be familiar with topics, for example, subnets in network configuration, S7 communication between PLCs, SFC and SFB blocks for put, get, receive and send data, configuring profibus network with slaves, diagnostics, reading and writing data.
You will better know S7-400 family with modules, rack system, process image partioning, multicomputing, startup characteristics, interrupts, special function modules, interface modules and communication processors.
You will get knowlegde about enginnering tools and option packages of Simatic Step 7 family, S7-Graph, Higraph, S7-SCL structured control language, S7-CFC continous function charts, S7-SFC sequental function charts and other features.
Before you start it would be wiser decision to look at the first training, if you are a beginner at Simatic world, this course will be really useful and helpful i guess. And I suggest you to spare at least couple of days for this training, and you are going to need some free time to do exercises at your own pc and if it's possible you can use real hardware or democase to make some practice.
I hope you will enjoy this course.
With sincerely.
Caner Sezer.
