As you can see, there is already “Main ” there for us. There are several different types of blocks that can be used in a Siemens PLC. Siemens PLC programming - Totally Integrated Automation (TIA) Portal Test Project Siemens PLC Program Blocks Now for the purposes of this tutorial, it doesn’t much matter which PLC we use, but we’re going to select a CPU 1511-1 PN as shown in the screengrab below. The Profibus technology is older and communication is slower than ProfiNET, but it still remains prevalent in automation today.

In this case, the “17” in CPU 317 indicates the CPU has 1 MB of work memory.Ī DP connection can be used for Profibus devices to communicate over the PLC network in the same way as ProfiNET. If a PLC identifier is CPU 317-2 PN/DP, this means it is a CPU in the 300 series, with 2 ethernet ports and 1 MPI or DP connection. The “11” in the CPU 1511 denotes how much memory the device has, for instance, the CPU 1511 has 150 KB of working memory for programs and 1 MB for data, a CPU 1513 is the same CPU series, but it has 300 KB of working memory for programs and 1.5 MB for data. If a PLC identifier is CPU 1511-1 PN, this means it is a CPU in the 1500 series, and it has 1 ethernet port, signified by the 1 PN. The prefix for Siemens PLC with ethernet, referred to as ProfiNET, is “PN”.

Firstly how do we intend to connect to the PLC? An ethernet cable is fast becoming the most popular way to connect because of its speed and versatility. When selecting a PLC there are a few important things to consider. Siemens PLC programming - Totally Integrated Automation (TIA) Portal Creating a New Project The one highlighted is the one we need for the version of TIA Portal we’re using V14 SP1. Start by opening the Siemens Automation Licence Manager to transfer the license from the license stick to your programming machine. With Siemens, the license itself comes on a USB license stick. Usually, they will be purchased for a particular project and the license used accordingly. In this tutorial, we are going to look at how to get started on a project using TIA Portal, from setting up which PLC we’re going to use, to adding some functionality to a program.įirstly, it is important to note that you need a valid license to begin programming with SiemensTIA Portal, and they don’t come cheap. With Siemens TIA Portal, programmers are able to use the latest software to intuitively code small projects to large projects with everything else in between.

Siemens is one of the major players when it comes to PLC programming, and it is regarded very highly in the industry.
