Hello zezo, If I understand correctly...... point 3. How can you load projects to a memory card and back again to a PG ... |

Hello zezo; The basic, noirmal way to download blocks "directly to MMC" is to do a program download. As you can see in the attached file, the selected blocks (or the complete program, if you choose that option) are then sent to the load memory of the CPU, which in your case is the MMC slotted in the CPU. For a more complete description of the p^rocess, check chapter 19 of the following manual: SIMATIC Programming with STEP 7 V5.5 https://support.industry.siemens.com/cs/fr/en/view/45531107 To do this operation you need either a serial (MPI/Profibus) adapter, such as the CP 5711, or a standard Ethernet cable connected to a CP 343-1 on the PLC rack. Use the Set PG/PC interface selector (see chapter 2.2.2) to set the communication parameters between Step 7 and the CPU. Alternatively, if you have a PG (Siemens programming device) with an integrated EEPROM writer, of an external Siemens EEPROM writer, you could write the program to the MMC and then slot it in the cPU bay, so that the program is read y the CPU on power-up. Please do not attemt this with a non-Siemens EEPROM writer, you will reformat the MMC and render it useless for your CPU. Hope this helps, Daniel Chartier |
