A utomation and Drive s - SCE T I A Training Document Page 10 of 25 Module Retentivity Your CPU 31xC has retentive me mory. Retentivity is implement ed on the MMC and on the CPU.
A utomation and Drive s - SCE T I A Training Document Page 11 of 25 Module 3. CREATING THE HARDWARE CONFIGURATION FOR THE CPU 314C-2DP In Step 7, files are managed with the 'SIMATIC Manager'. Here, program blocks can be copied, for example, or called for further processing with other tools by clicking on them with the mouse.
A utomation and Drive s - SCE T I A Training Document Page 12 of 25 Module The hardware configuration of the PLC is mapped in the 'SIMATIC 300 Station' and 'CPU' folders. This is done in the special case where a c onfiguration is created with the CPU 314C-2DP.
A utomation and Drive s - SCE T I A Training Document Page 13 of 25 Module 3. The project is now assigned the name 'CPU314C_2DP' under 'Name' ( → CPU314C_2DP → OK) 4.
A utomation and Drive s - SCE T I A Training Document Page 14 of 25 Module 5. Open the configurati on tool by double-clicking on 'Hardw are' .
A utomation and Drive s - SCE T I A Training Document Page 15 of 25 Module 7. Insert a rail by double-clicking on 'Rail' ( → SIMATIC 300 → RACK-300 → Rail).
A utomation and Drive s - SCE T I A Training Document Page 16 of 25 Module 8. From the hardware catalog, you now can sele ct any of the modules that are also plugged into the real rack and insert them in the configuration table.
A utomation and Drive s - SCE T I A Training Document Page 17 of 25 Module 9. In the next step, we drag the CPU 314C-2DP ont o the second slot. When this is being done, the order number and the version of the CPU can be read on the front of the CPU. ( → SIMATIC 300 → CPU-300 → CPU 314C-2DP → 6ES7 314-6CF00-0AB0).
A utomation and Drive s - SCE T I A Training Document Page 18 of 25 Module 11. The properties of some modules can be altered ( → Click on module → Change properties → OK). For example, a clock memory c an be specified for all CPUs ( → Cycle/Clock memory → ∨ Clock memory → Memory Byte 100).
A utomation and Drive s - SCE T I A Training Document Page 19 of 25 Module 12. With most S7-300 CPUs, the addresse s of the I/O modules can be altered. This is done by double-clicking on the correspondi ng modules and altering their settings in the 'Addresses' tab.
A utomation and Drive s - SCE T I A Training Document Page 20 of 25 Module 13. By clicking on the and buttons, the configuration table is now first stored and converted, and then loaded into the PLC.
A utomation and Drive s - SCE T I A Training Document Page 21 of 25 Module 4. WRITING A STEP 7 PROGRAM We are writing the program to be tested in the st atement list language (STL), and it only contains two lines. Here, the frequencies of the MB100 clock memory byte activated in the hardware are to be read out on an output byte.
A utomation and Drive s - SCE T I A Training Document Page 22 of 25 Module 15. In the SIMATIC Manager, double-click on the 'OB1' block to open it ( → OB1) 16. As an option, you can enter the properties of the OB1 for documentation purposes and accept them with 'OK' .
A utomation and Drive s - SCE T I A Training Document Page 23 of 25 Module 17. 'LAD/STL/FDB Program S7 Blocks’ is an editor which allows you to create your STEP 7 program as you require. To this end, the OB 1 organization block with the first network has already been opened.
A utomation and Drive s - SCE T I A Training Document Page 24 of 25 Module 5. TESTING THE STEP 7 PROGRAM The STEP 7 program to be tested can now be loaded into the PLC. In our case, this is only OB1. 18. Save the organization block with and load it into the PLC by clicking on .
A utomation and Drive s - SCE T I A Training Document Page 25 of 25 Module 19. To start the program, move the key switch to the RUN position. Click on the symbol to view the program in 'OB1' .
