Automating with LOGO!

LOGO! is a mini SIEMENS PLC designed for simple automation tasks. It is usually seen in control lights for stairs, irrigation control or automatic gates. While these tasks seem simple mini PLC that allows to add analog inputs and a communications module.

Here I leave a link to an online course free of charge and most relevant links LOGO!.

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.
