Hi   i've to make a simple project related to automation using plc so anybody plz tell me which plc will i use related to company SIMENS or FATEK?

I'm assuming this is a student project. I would suggest Siemens, as it is most widely used, and would give you some valuable experience to apply to your career.

Hello, I would suggest Siemens too, also PLC start.
Good luck!

It depends on the application
In Fatek some jobs and tasks that are not available in small Siemens PLC S7-200

As no doubt many have said and will say, it depends on what you are about to do. All systems have their "up's and down's". Personally I have not used Fatek so I cannot say anything about them but Siemens does have one thing speaking for them, if you are a beginner, and that is that they have an extensive online support system. You can also register with their online support, free of charge, and access manuals, data sheets, connection diagrams and program examples; some of which are very helpful and coherent. I know many here who have had complaints about their phone support but I myself cannot say I have ever had any such issues. Different countries, different support personel I suppose. Siemens is however a rather expensive choice.

Other than that, good luck...
