Profibus DP
Basic is the name of the Profibus communication system. Used by location, Profibus DP, Profibus PA has various names such as. Profibus DP (Distributed Process) process small groups to work on its own automation system used to communicate with control center. Automation system design, the overall structure is divided into small groups to process.This process makes the groups and the central operations center in accordance with orders from the control unit will send updated information. In this way, the end of the system from a central location to the point of access is provided. Take, for example, a plating facility. Plant automation controller with a PC or PLC, the communication line is in connection with the most extreme points. Such a system will not need the operator to control all the components individually. The control unit is pre-defined parts to be processed through the program are selected and the process starts.After the operation control unit as defined in the program provides access to the necessary units and performs. For example, covered parts of the bathroom when the track is connected to rectifier current voltage values calculated by the number of charger automatically executed by the system. The time required to complete, the system sends the necessary commands to stop rectifier and rectifier stops. MRS electroplating rectifiers, developed for the production of single or group of devices with interfaces provided full integration of the automation system. Group interface structure, all the rectifiers in the plant to a common data line is connected to the Profibus DP interface.This interface is the central unit keeps the information it receives rectifiers and rectifier system administrator transfers the information collected to date. Profibus line performance of this technique is increased. Drawback of the system is more than the number of rectifier applications, data refresh rate decreases.Normally defined groups of up to 20 rectifiers. This number will be 1sec for the refresh rate. Direct access to a particular device or groups of people need a quick refresher or a single interface application minimized to get there. Single interface is the use of each device has its own Profibus DP interface. automation control unit can provide direct access to any device at any frequency. Unused devices do not need the processing of the data. According to the application allows the Group. Rectifiers high-speed communication system connecting directly to a more current data would be studied. Profibus DP system is based on periodic two-way data exchange. The central control unit connected to it by a certain period in the sub-groups and sub-groups will send study data is the current status information. Galvano rectifiers similar jobs in the state.The system is needed to run rectifier current, voltage and sends the command information. Rectifier their output current, voltage values and sends current status information. Thus, in the center of problems that may rectifier unit can be monitored. If necessary, treatment was stopped and allow the operator intervention is provided. |
