ABB通讯（国外英文资料） The data communication between the Siemens PLC and ABB inverters based on profibus-dp was published in: nanjing road automation system co., LTD. category: unclassified This article introduces the Siemens SIMATIC s7-300 series PLC and ABB ACS600 series converters through the profibus-dp field bus data communication. Mainly discusses the system configuration and communication protocol, STEP7 programming software environment programming and the system hardware configuration and communication key technology such as frequency converter running parameters Settings. 1, the introduction Profibus is one of the most successful field buses in the current industrial control system and is widely used. It is not dependent on the production factory, the open field bus, and all kinds of automation equipment can be exchanged through the same interface protocol. Profibus-dp (DistributedI/OSystem, distributed I/O system) is a kind of optimized module, have higher data transfer rate, applied to the communication between system and external equipment, remote I/O system is particularly appropriate. It allows for high-velocity, periodic, small batch data communication, which is applicable to time-demanding automatic control systems. Profibus-dp fieldbus system can make a lot of field devices (such as PLC, intelligent transmitter, frequency converter) in the same bus two-way information digital communication, so can easily use different manufacturer production control measurement system are connected into a network of sin. BaoDeCai board co., LTD., jinan jinan group corporation invested in 2003, the annual output of 200000 tons of large color plate production base, the production line of curing furnace, heat conduction oil furnace, gas, hydrogen production in the gas system must to secondary pressurized gas by the gas pressure machine can meet the requirements of production process, the gas pressure machine control system adopts the process of profibus-dp field bus communicat
