11、ble to attach to itself the SIMATIC S7-300 by the PROFIBUS with the protocol profile distributed I/O (DP).The parameterizing of the PROFIBUS parameters for the PLC, such as the configuration of the PROFIBUS network, takes place with the software STEP 7. The requirement is the CP342-5DP and additiona

12、lly the software “NCM S7 PROFIBUS “ (Contained already in STEP 7 V5.x!), so that the user has a uniform configuration tool for centralized and distributed configuration. For the SIMATIC S7-300 with the CP342-5 as a Combimaster, the following protocol profiles are at your disposal: DP- Interface as m

13、aster or slave according to EN 50170. PROFIBUS-DP (Distributed I/O) is the protocol profile for the connection of the distributed I/O/field equipment with a quick reaction time. SEND/RECEIVE- Interface (AG/AG) according to the SDA-Service (Layer 2 of the PROFIBUS). SEND/RECEIVE (FDL- Interface) offe

14、rs functions with which the communication between SIMATIC S5 and S7 are under one another and they can simply and quickly be realized to the PC. S7-Functions. These offer optimal communication in the SIMATIC S7/M7/PC-connection.On the part of the user program, the transmission of the data range for

15、the DP and FDL communication is activated through programmed FC-Block calls and monitoring of effective execution monitored.The block calls for the important communication FC blocks are found in the library “SIMATIC_NET_CP“. In order to use these functions, the function must be copied into the proje

16、ct. Note: Here 2 SIMATIC S7-300 with theCP 342-5DP are appointed to the PROFIBUS as a master and as a slave.3. commissioning the Profibus ( Master cp 342-5DP / Slave cp 342-5DP)In the following example, the commissioning of a mono master system with the SIMATIC S7-300 with CP 342-5DP as a master and

17、 an additional SIMATIC S7-300 with a CP 342-5DP as a slave is described.For the testing of the configuration, a program will be written in which an input (SET) can be preset in each PLC. This byte is transferred over the PROFIBUS to the other PLC and can then be displayed over a display byte (DISPLA

19、munication Byte1For the connection of the two CPU342-5DP, whereby one is set as a master and the other as a slave, the following steps must be followed.1. The central tool in STEP 7 is the SIMATIC Manager, which is opened here with a double click ( SIMATIC Manager).2. STEP 7- Programs are administer

20、ed in projects . Such a project will be created ( File New). 3. Give the Name CP342_CP342 to the project ( CP342_CP342 OK).4. Highlight your project and insert a PROFIBUS Subnet ( CP342_CP342 Insert Subnet PROFIBUS).5. Then insert a SIMATIC 300-Station ( Insert Station SIMATIC 300-Station). 6. Chang

21、e the name of the station to Slave ( Slave). 7. Open the configuration tool for the Hardware with a double click ( Hardware). 8. Open the hardware catalog with a click on the symbol ( ).There you will see the directories are divided into the following:- PROFIBUS-DP, SIMATIC 300, SIMATIC 400 and SIMA

22、TIC PC Based Control,all module racks, modules and interface modules for the configuration of your hardware configuration are made available.Insert a Rail with a double click( SIMATIC 300 RACK-300 Rail). After the insert, a configurations table for the configuration of the Rack 0 appears automatical

23、ly.9. Now all modules can be chosen out of the hardware catalog and inserted into the configuration table and are also inserted into your rack. To insert, you must click on the name of the respective module, hold the mouse button and Drag & Drop the module into a line of the configurations table. We

24、 will begin with the power supply PS 307 2A ( SIMATIC 300 PS-300 PS 307 2A). Note: If your hardware differs from what is shown above, then you must select the appropriate modules from the catalog and insert them into the rack. The part numbers of the individual modules, which are found on the compon

25、ents, are indicated in the footer of the catalog.10. In the next step, we drop the CPU 314IFM into the second card location. This allows for the part number and version of the CPU to be read off ( SIMATIC 300 CPU-300 CPU 314IFM 6ES7 314-5AE03-0AB0 V1.1 ). Note: The addresses of the integrated in-/ou

26、tputs by the CPU314IFM can be read into the hardware configuration. However, they are directly on the CPU. They are the digital inputs IB124 and IB125 such as I126.0-I126.3. The digital outputs have the addresses QB124 and QB125. The analog inputs are found on PIW128, PIW130, PIW132 and PIW134. The

27、analog output is found on PQW128.11. Then we drag the communication processor for the PROFIBUS CP 342-5DP onto the fourth slot. Now the order number and version of the model can be read off the front ( SIMATIC 300 CP-300 PROFIBUS CP 342-5DP 6GK7 342-5DA01-0XE0 Product Version 2). Note: Slot number 3

28、 is reserved for interface modules and remains empty. The order number of the module is displayed in the footer of the catalog.12. By the entering of the communication processor, the following window appears, in which you assign a PROFIBUS address to the CPU 342-5DP and must already choose the first

29、 PROFIBUS net. When you want to alter the parameter of the PROFIBUS net, you must highlight it and then click on Properties ( 2 PROFIBUS(1). 13. Now you can choose the Highest PROFIBUS Address (here 126), the Transmission Rate (here 1,5 Mbit/s) and the Profile (here DP). ( OK). 14. Now the addresses

30、 of the communication processor in the I/O address space of the CPU are noted (Here: PI 256.271 / PQ 256.271). Choose the properties of the communication process through a double click on the CP 342-5DP ( CP 342-5). 15. Set the Operation Mode to DP slave and accept with OK ( Operation Mode DP slave

31、OK). 16. The configuration table is saved and compiled now with a click on . Then the hardware configuration is closed with a click on x ( x). 17. Now in SIMATIC Manager enter an additional SIMATIC 300-Station ( SIMATIC Manager Insert Station SIMATIC 300-Station).18. Change the name of the station to Master ( Master).19. Open the configuration tool for the Hardware with a dou
