An embedded system is typically made to do one set of task or similar sets of tasks. An internet router uses an embedded system and so does an MP3 player. There are usually some options as to how the task are carried out, such as choosing to set a password for your router or choose a song on the MP3 player.
PLC's on the other hand, operate using IF-THEN instructions. If the water gets too high, THEN open the valve to release some. IF the water gets too low, THEN turn on the pump. A PLC can be used to operate a whole process, like brewing beer or refining fuel. Most PLC's connect to many different types of sensors for inputs. Some examples of these sensors are: flow, pressure, temperature, and level, but there are many more. Outputs usually are connected to relays to control power to electrical devices that require more current than the PLC can put out.
A PLC may also interface with an embedded system. There are some cases where either will do. One commonly used appliance that would work with either is an automatic coffee maker. Also, clothes washing machines used to use simple PLC's while many of the new ones use embedded systems.

What makes PLC communicate with SCADA?
PLC communicates with SCADA through industrial communication protocols like Modbus, Profibus, or Ethernet/IP. The PLC collects real-time data from machines, and SCADA displays, monitors, and controls it. From what I’ve seen on-site as a company photographer, this connection keeps everything visible, manageable, and efficient for smooth industrial automation.
How much an PLC have outputs and inputs maximum?
There are PLC with fixed inputs and outputs. There are modular ones which can be added on with inputs and outputs. So number of input and output of a PLC is actually based on the type of PLC you choose. Different types are available in the market.
Choosing the Best PLC Training?
A programmable logic controller, or PLC technician, is a professional who designs, installs and repairs automated control systems and other equipment in manufacturing facilities. PLC technicians are highly trained professionals who should possess excellent problem solving and technical skills. To obtain these skills, future technicians must undergo specialized PLC training.PLC Training OptionsIf you want to become a PLC technician, there are a few different training options available to you. Your first option is to complete a certificate program at a vocational school. These programs typically last around nine months and cover a wide range of topics. Areas of study include electrical systems, data transfer, schematics, central processing units, robotics, technical mathematics, pneumatic systems and process control. The benefit of attending a vocational school is that these programs usually take their time covering the skills and abilities students will need in the field.If you would prefer to study at home, it is also possible to complete your PLC training online. Online programs are offered by both vocational schools and community colleges. These programs generally provide students with lessons either online or on CD-ROM. After completing a training program, students will usually be offered a certificate proving their credentials. While online study will not provide hands-on training, it does give students the opportunity to study at their own pace and complete their training faster.Students who have experience working in industrial electronics can also complete shorter training workshops. These workshops typically last for several days and prepare students to seek entry-level employment as a PLC technician. Workshops are also available for PLC technicians who want to continue their education and advance their career. If you have prior experience, a PLC workshop or seminar might be all you need to gain the necessary skills.To choose the best PLC training, carefully consider your current skill level, goals, and preferred learning method. If you are a hands-on learner, completing an online program might not prepare you as well as traditional classes. Fortunately, if you want to begin a career as a PLC technician, there are dozens of programs, workshops and schools for you to choose from.
What is the profibus of the s7 plc?
PROFIBUS (Process Field Bus) is a standard for fieldbus communication in automation technology, enabling devices such as sensors and actuators to communicate with controllers like the Siemens S7 PLC. It allows for real-time data exchange and can connect multiple devices over a single network. PROFIBUS supports both process automation and factory automation applications, providing a robust and flexible communication solution. The S7 PLC can interface with PROFIBUS networks using dedicated communication processors or interfaces, enhancing its ability to integrate with various automation systems.
