1. The system should first calculate the input and output (I/O) points according to the control requirements, and reserve a 10% margin on the basis of the actual number of points when selecting PLC, in order to prepare for the expansion or transformation of the system.
2. Determine the load type according to the PLC output load is DC type or AC type, is high current or low current, and the frequency of PLC output point action, so as to determine whether the output use relay output or transistor output, or thyristor output. It is very important to choose different output modes for different loads for the stable operation of the system.
(3) Storage capacity and instruction execution speed is an important indicator of PLC selection, the general storage capacity, the faster the PLC price is higher, although the foreign manufacturers of products are generally the same, but there are some differences.
4. The choice of “COM” points, different PLC products, the number of “COM” points is not the same, some a “COM” point with 8 output points, some with 4 output points, there are also 1 or 2 output points. When the types of loads are large and the current is large, a “COM” point with 1 to 2 output points is used, and when the types of loads are small and the number is large, a “COM” point with 4-8 output points is used.
5. Because the development software of each manufacturer is different, systematic compatibility is also the focus of purchase, and no fully compatible products have been found, PLC products should be rationally selected according to the system.
6, the choice of programmer: PLC programming can be taken in three ways: first, with a general handheld programmer, it can only be programmed with the statement in the statement table specified by the manufacturer. This method is easy to debug on site and small in size and low in cost, but it has low efficiency and few types of suitable machines, and is more suitable for systems with small system capacity and small dosage. The second is graphic programmer programming, this way uses graphic programming, convenient and intuitive, general electrical personnel can be applied freely in the short term, but the programmer price is higher. The third is to use IBM and its compatible personal computer +PLC software package programming, this way is an efficient way, is also a commonly used way, but most of the software packages are expensive. However, some software packages can be downloaded for free online.
7. Try to choose the products of large companies, because the product quality is guaranteed, and the technical support is good, the general after-sales service is also good, which is conducive to the expansion of the product and the software and hardware upgrade in the future.
Compared with the general computer language, PLC programming language has obvious characteristics, it is different from the high-level language, but also different from the general assembly language, it should meet the requirements of easy to write, but also to meet the requirements of easy debugging. At present, there is no programming language that is compatible with all manufacturers’ products. For example, Mitsubishi’s products have their own programming language, and OMRON’s products have their own language. But no matter what type of PLC, its programming language has the following characteristics:
1, graphic form instruction structure: the program is expressed in a graphical way, and the instructions are composed of different graphic symbols, which is easy to understand and remember. The software developers of the system have programmed the independent computing functions required in industrial control into symbolic graphs, and users combine these graphs according to their needs, and fill in the appropriate parameters. In the logical operation part, almost all manufacturers use a ladder diagram similar to the relay control circuit, which is easy to accept. For example, Siemens also uses the control system flow chart to express it, which uses the graphical symbols of binary logic elements to express the control relationship, which is intuitive and easy to understand. More complex arithmetic operations, timing counting, etc., are generally also represented by reference to ladder diagrams or logic element diagrams, although the symbolism is not as good as the logical operation part, and they are also popular with users
2, clear variable constant: the graph is equivalent to the operation code, which specifies the operation function, and the operand is filled by the user, such as: K400, T120, etc. The variables and constants in PLC and their value range are clearly defined, determined by the product model, and can be consulted in the product catalog manual.
3, simplified program structure: PLC program structure is usually very simple, typical block structure, different blocks complete different functions, so that the debugger of the program has a clear concept of the control function and control sequence of the entire program.
4, simplify the application software generation process: the use of assembly language and high-level language to write programs, to complete the editing, compilation and connection of the three processes, and the use of programming languages, only need to edit a process, the rest is automatically completed by the system software, the entire editing process is carried out under the human-machine dialogue, does not require users to have advanced software design capabilities.
5, strengthen debugging means: whether it is assembler, or high-level language program debugging, it is a headache for editors, and PLC program debugging provides complete conditions, the use of programming, the use of PLC and programming buttons, display and internal editing, debugging, monitoring, and in the software support, diagnosis and debugging operations are very simple.
