Hello Lucky; Wow, so many quations... You say you know about inputs (I) and output (Q) addresses, that is a good start,. These are digital input/output addresses that represent the value of a single bit at a time; they are generated by digital input/outut modules. Analog addresses contain values that represent numbers coming from sensors in the field , temperature, pressure, torque, mtor speed... So they are linked to analog modules in your configuration. Program blocks are known as Functions (FC) or Function Blocks (FB), the main difference between them is that a FB is linked to a specific DB (Data Block) that acts as its memory area. You can also create Global DBs as seperate memory areas you will use to contain the process vlues of your project, the parameters of your processor, or anything you need to remember in your application. There is much t know to become a competent Siemens programmer. and it is impossible to answer every queston you asked inside ths thread. Here are documents you can use to start your discovery of the S7-300 and S7-400 families of CPUs, programming with Step 7 v5.x: (as you seem to be doing now, based on my interpretation of your post). - Working with Step 7 v5.4, Getting Started (basic tutorial document, with links to sample projects in Step 7, see screenshot below). https://support.industry.siemens.com/cs/ww/en/view/18652511 - Programming with Step 7 v5.4 (more complex document, more detailed, more informative) https://support.industry.siemens.com/cs/ww/en/view/18652056 If you arre working instead with TIA Portal (SStep 7 v16, for example), this video tutorial will give you the basics of this platform: - Getting Started Step 7 and WinCC v16 (video): https://www.youtube.com/watch?v=le9ExrCcpB0 Hope this helps, Daniel Chartier |

Here some newer resources: [The TIA Portal Tutorial Center (videos)] [ Siemens Web Based Training ] [SIMATIC S7 S7-1200 Programmable controller] Start here: [Program block concept]
