ABB IW93-2 HESG440356R1 HESG216678/B PLC is divided into two categories according to the structure and module type, according to the application environment is divided into field device and control room device two categories; According to the CPU word length, it is divided into 1 bit, 4 bit, 8 bit, 16 bit, 32 bit, 64 bit and so on. Starting from the application point of view, it can usually be selected according to the control function or input and output points. The I/O points of the whole PLC are fixed, so the user’s selection is small, and it is used for small control systems. Modular PLC provides a variety of I/O cards or cards, so users can reasonably select and equip the I/O points of the control system, convenient and sensitive function expansion, usually used for large and medium-sized control systems. The selection of input and output modules should be the unity of thinking and application requests. For example, for the input module, we should consider the application request of signal level, signal transmission interval, signal blocking, signal power supply method, etc. For the output module, the type of output module should be considered, usually the relay output module has the characteristics of low, wide application voltage scale, short life, long response time, etc. IW93-2 HESG440356R1HESG216678/B thyristor output module is suitable for switching frequency, electrical low power factor load occasions, but more expensive, overload can be poor. The output module also has DC output, AC output and analog output, etc., which should be common with the application request. IW93-2 HESG440356R1 HESG216678/B can be reasonably intelligent input and output modules according to the application request, so as to improve the control level and slowly reduce the operation cost. Think about whether expansion racks or remote I/O racks are required. PLC power supply, in addition to the introduction of equipment together with the introduction of PLC should be planned and planned according to the requirements of the product instructions, usually the PLC power supply should be planned 220VAC power supply, and the domestic grid voltage. The main application occasions should be uninterruptible power supply or regulated power supply. If the PLC itself has an available power supply, it should be checked whether the supplied current meets the application request, otherwise it should be planned for external power supply. In order to avoid the introduction of the PLC due to misoperation of the external high-voltage power supply, it is necessary to block the input and output signals, and the IW93-2 HESG440356R1 HESG216678/B can sometimes be blocked by a simple diode or fuse tube. Because of the development of computer integrated chip skills, memory has been reduced, therefore, in order to ensure the normal operation of the project, the memory capacity of the PLC is usually requested, and at least 8K memory is selected according to 256 I/O points. IW93-2 HESG440356R1 HESG216678/B When clutter control is required, a larger capacity and higher level of memory should be selected.
