SIMATIC PLC S7-200

The Siemens S7-200 PLC is a very popular choice, when you start PLC Image result for Siemens plc S7 200programming. It is the cheapest PLC from Siemens, and it is very easy to begin programming. The Siemens S7-200 has a limited variety of functions, but it certainly also has a lot of advantages. With this article, you will be ready to start configuring and programming the Siemens S7-200 PLC.

As you may know, the PLC product line from Siemens is named S7 or Step 7 PLC’s. The smallest PLC model is the Siemens S7-200 PLC. In the line of PLC’s you will also find the Siemens S7-300, Siemens s7-400, Siemens S7-1200 and the most advanced PLC system in the line; Siemens S7-1500.

Even though the S7-200 PLC system is still the cheapest it is now the latest series of Siemens PLC’s. Siemens has made a new kit for learning PLC programming. If you are serious about learning PLC programming you should take a look at the Siemens S7-1200 Starter Kit, which comes with the latest STEP 7 Basic TIA Portal (version 13).

Beside being cheap, the Siemens S7-200 PLC is also quite user friendly. If you read further down this article, you will notice that this Siemens PLC is actually very easy to connect to, configure, program and debug your programs. You can be programming ladder logic for Siemens S7-200 after just a quick configuring of the PLC programming environment.

The reason, this PLC is so easy to work with is that you use Siemens STEP 7 Micro/WIN to program the PLC. More about that piece of PLC programming software later in this article.

First a little look on the various modules you can get for the S7-200 PLC system.
