ISTVIBH2BCC ISTVIBH2BCC ISTVIBH2BCC emphasized that the programmable controller is qualitatively different from the drum and mechanical sequential controller described in the past. Due to the introduction of a new generation of electronic devices such as microprocessor and semiconductor memory, PLC and the specified instructions for programming, can be modified flexibly, that is to use software…
IS215VCMIH2CC IS215VCMIH2CC IS215VCMIH2CC characteristics. In 1980, the Electrical Manufacturers Association of America (NEMA) gave him a new Programmable Controller, or PC. In 1982, the International Electrotechnical Commission (IEC) specifically for programmable controller under the strict definition. However, PC this abbreviation name has already become a synonym of Personal Computer (Personal Computer) in China, in order…
IS215VCMIH2BB IS215VCMIH2BB IS215VCMIH2BB computer. In 1969, the United States Digital Equipment Company (DEC company) developed the first programmable controller PDP-14, in the United States General Motors Company on the production line trial success, and achieved satisfactory results, programmable controller was born. Since the advent of programmable controller, the development of extremely rapid. In 1971, programmable…
IS215UVEH2AE IS215UVEH2AE IS215UVEH2AE In 1968, America’s biggest carmaker, general motors (GM) in order to adapt to the need of production technology constantly updated, ask for a more reliable than a relay, and the function is more complete, the response speed faster new industrial controller, and puts forward a new generation of controller from the perspective…
IS215UCVEH2AE IS215UCVEH2AE IS215UCVEH2AE matching compiler, final reoccupy special machine (read-write) special one-on-one to send the PLC program, during the system debugging, and debugging cost a huge increase in debugging time, And extremely detrimental to future maintenance. The control accuracy is far from the same. This determines why in large and medium-sized control projects (more than…
IS215UCVEH2A IS215UCVEH2A IS215UCVEH2A program after installation is a close association between any station, any function, any controlled device is interlocking control, coordination control; And the single use of PLC connected with each other constitute the system, the station and station (PLC and PLC) between the connection is a loose connection, is not a coordinated control…
IS215ACLEH1B IS215ACLEH1B IS215ACLEH1B customer used a large motor on site, up to hundreds of kilowatts, when contacted by phone, I confirmed that the motor carbon brush did not ignite, and the fault machine had been in use, after the fault occurred, no matter light load or heavy load, armature current fluctuated greatly. 1 DCS is…
IS215ACLEH1AB IS215ACLEH1AB IS215ACLEH1AB connected to the power supply like burp. Abbdcs550 is abb’s upgrade board on the basis of dcs400 series governor. The hardware changes are not much, but the software is very different. The application of software is closer to dcs800 series products. The Dcs550 governor also optimizes some of the hardware that can…
IS200VSVOH1BDC IS200VSVOH1BDC IS200VSVOH1BDC is that the dcs400 excitation control is also integrated in this board, and the dcs400 software is not support excitation off this function, which brings some difficulty to the maintenance. In the actual maintenance, abbdcs400 caused by excitation fault is the most. There is the control power supply, the control power supply…
IS200VSVOH1B IS200VSVOH1B IS200VSVOH1B the same time, DCS installation and debugging, especially with the plant power related subsystem debugging, so that its put into operation before the power supply, to meet the electrical power supply, the plant of the process system of the division of trial operation requirements. First of all, abbdcs400 series, abb DC governor,…
