Automating with S7-200

The S7-200 PLC is the low end of the line SIMATIC. Still this team is usually seen in machines of all kinds, from simple sequences of contacts for control of lights, to large positioning control machines and input / output high response. A PLC which allows communications of all kinds: MODBUS Master / Slave, GSM communication to send and receive SMS, PROFIBUS DP (slave only), AS-Interface, Ethernet with web server / mail server / FTP, and how to Freeport create our own protocols or adapt it to non-standard protocols such as for receiving data from a barcode reader.

Here I post a link to free online course and system manual. I am about to open a new blog dedicated to this team to study individually each one of the possible applications.

Some Benefits of Diesel Engines

If you’ve owned a diesel powered vehicle in the

past or if you own one now, you no doubt appreciate

the qualities this engine provides you with.  More

torque, better fuel economy, and easier maintenance

are but a few of the attributes of owning diesel

powered vehicles.

However, there are some motorists that still

complain about the engine’s weak power, especially

when accelerating from a full stop.  What you

may not be aware of is the fact that a diesel

engine can be tweaked to give more power without

harming the fuel economy.

Diesel engines use air compression to create

combustion versus the fuel/air mixture that is

required by gas engines.  This attribute means

that diesel engines don’t require spark plugs

and therefore don’t need to be tuned up.

Diesel fuel has a much high fuel density than

gas, which results in fuel economy increases

of 20 – 30% over gasoline powered vehicles.

Diesel engines are also cheaper to maintain as

they have less parts than that of a gasoline

powered engine.  The life span of a diesel

engine is also much longer.

If you’re looking for torque, for pulling a

boat or other equipment, then the diesel

engine has the supreme advantage.  Diesel

engines are surely slower, especially when

starting from a dead stop, although when you

climb hills or go over bridges, the diesel

engine is surely up to the task.

With trucks, diesel is normally the leader

over gas engines in terms of performance and

miles per gallon.  Diesel trucks will get

more miles than gas trucks, and the price for

diesel is a bit cheaper than gas these days.

And with gas prices on the rise, diesel will

continue to dominate for a long time to come.

Automating with Step7 – S7-300/400

Time for the greats of the SIMATIC family. The S7-300 and S7-400. These PLC are scheduled from a single interface with the same language and same procedures.

These families are integrated into the SIMATIC Manager, a true project manager who not only allows us to create programs but also interconnect equipment, manage HMI panels, SCADA systems, variable speed, field instruments, and all types of equipment used in industry. All this is due to the Siemens TIA concept (Totally Integrated Automation).

It’s much there is to learn about and SIMATIC Step7 Manager, so I leave here some links to free courses Siemens. They are downloaded to the PC and are in English only.
1) The SIMATIC Manager
2) Architecture SIMATIC S7
3) programming languages LAD, FBD and STL
4) Communication with SIMATIC S7
5) Display – HMI integration
6) Functions test and operation
7) The language S7-SCL high (similar to Pascal)
8) The graphic language S7-GRAPH

Communicating with PROFINET

EVOLUTION OF A PROFIBUS PROFINET

Within the SIMATIC automation systems have existed various field buses. They have evolved over time into new technologies. For example, buses SINEC L1, L2 or SINEC SINEC H1.
In 1989, in order to allow users to interconnect equipment from different manufacturers Profibus protocol was developed through the work of fifteen companies and institutes, including Siemens company. Profibusprotocol is an evolution of SINEC L2, though unsupported each other. It is not uncommon to find operating IM308B communication modules for the S5-135U, S5-95U communicated with integrated port SINEC L2.
If we study the protocol Profibus according to the ISO / OSI modelfor communications protocols see that in the layer 1, physical layer, uses the standard RS485 . This is a two-wire differential bus is not twisted and shielded.
Profibus today has approximately 20 million nodes installed worldwide, and proved one of the best field buses.
INTRODUCTION PROFINET
Still, the market demands a step further and thus bringing the PROFINET standard: a bus Ethernet based industrial communication industry.
