System Reliability Requirements: The reliability of the general system PLC can be met. For systems with high reliability requirements, consider whether to use redundant systems or hot standby systems. PLC should be unified possible. Mainly consider the following three aspects: The model is unified, and its modules can be used as backup for each other, which is convenient for the procurement and management of spare parts. The model is unified and its function and use method are similar, which is conducive to the training of technical forces and the improvement of technical level. The model is unified, its external equipment is universal, resources can be shared, easy to network communication, and it is easy to form a multi-level distributed control system after being equipped with a computer.
Inherent human weaknesses: people have inherent weaknesses such as forgetfulness, error-prone, inattentiveness and emotional instability. A well-designed human-machine interface should minimize the amount of user memory when operating and using, and should strive to avoid possible errors; The user’s knowledge and education: the user’s education level determines his knowledge and experience of the computer system. China is the world’s largest market in terms of HMI demand, but it is not the world’s highest market in terms of HMI product sales, which means that low-end HMI users occupy a large share in China. The rapid development of national brands in recent years, taking low prices and other strategies, is attacking the low-end market in a big way, and has occupied a dominant position in the low-end market in China, winning the recognition of the majority of users. International brands are also gradually developing their economic products to capture the share of the low-end market. As a result, the overall performance of domestic HMI manufacturers has shown rapid growth due to their steady presence in the low-end market.
The Fourth Step: Communication Mode Preference is given to the HMI Panel itself with lower computer drive touch screen. Firstly, this is will be more convenient and simple in the definition of the subsequent project address and conversion, becuase if you choose Modbus compatible devices, it is necessary to convert the HMI touch screen monitoring address according to the rules of the definition of different lower computer(PLC) manufacturer, which not only greatly increase the workload of engineers and also easy to covert the wrong. Secondly, needing to draw up in advance, a communication program for the entire project. Do it need the ethernet to communicate with the upper computer, or need two rs485 to be maste or slave station communication, or through one rs485 and one rs232 communication to achieve.
It is good to choose a brand according to the needing of the customers or the market. But it is not for selecting a brand to decide, or more about to focus on its performance parameters, and to be used the functions achieved. Actually there is an attractive story behind the famous brand. So to choose a brand, try to achieve high practicality, to avoide waste one’s talent on a petty job. For example, Siemens, Mitsubishi, Proface, Panasonic brand…etc with a good performance, but before decision to select them, should consider, how many performance of HMI panel will be used for the project? Whether the cost paid matches the performance used on the project? See additional details on https://www.mochuan-drives.com/.
How To Solve Communication Failure Between HMI Operator Interface And PLC? When communication fails, some customers guess that it may be a problem with the touch screen all-in-one machine or the interface. Online simulation is to bypass the touch screen, use the PLC to connect directly to the computer, use our configuration software, connect the PLC’s own communication cable to the computer, conduct online simulation and see if the project can communicate.
The Macro instructions of HMI Human Machine Interface are based on C language and the system is developed on Linux. There are multi-types of HMI panel, mainly three types, multi touch capacitive hmi panel, plastic shell enconomic resistive hmi touchscreen panel and metal shell wide-temperature resistive touch screen and small home screen to meet different requirement from application scenarios and market needing. There are rich serial port such as rs485, rs232, rs422, ethernet etc to meet the master and slave to use. Mochuan human machine interface manufacturer suppors the size from 4.3inch to 32inch.
There are lots of temperature control in industry automation. It can select temperature module match the main module plc temperature controller, it also use independent temperature controller to control, both of them are to achieve temperature control. If wanna more flexibility in temperature control, maybe indenpendent temperature module is the first choice. Becuase it can operate without main module plc controller. Mochuan independent plc temperature module integrates an excellent self-tuning algorithm, and user can auto-tune with one button according to needs to accurately obtain PID parameters. Through rs485 communication port, communicate with upper computers of various brands, types of plc, touch screen hmi, configuration software and other upper computers to complete morecomplex logic temperature control.
Choosing the right industrial hmi touch screen panel and plc can not only adapt to the electrical room’s multi-interference operation environment, but also enable each cabinet to achieve intelligent operation management, intelligent maintenance safety, intelligent new energy generation, etc., in order to achieve the goal of enhancing the electrical room’s core competitive advantage and promoting the sustainable development of electricity.
Human-Computer Interaction (HCI): The science of designing, evaluating, and implementing interactive computing systems for use by people and the study of these phenomena. HCI and human-computer interface are two concepts that are closely related but not identical. The RelationShip Between Human Computer Interaction and HMI: Human-computer interaction is the interaction between a human and a machine, which is essentially the interaction between a human and a computer. Or from a broader perspective: HCI refers to the interaction between a human and a machine containing a computer.
