Hello Retox; I understand what you want to do, unfortunately Siemens does not provide a USB port on the S7-300 CPUs. The newer S7-300 (the ones that are on the market at this time) use Micro Memory Cards, from 64kB to 8 MB. The MMCs are used as Load memory on the CPU, so the program can be loaded and retrieved from them, and they can be used to transfer a program to a distant CPU if need be. These FAQs can give you more information:
Section 4. SIMATIC S7-300 CPUs and C7 Devices With MMC Bay https://support.industry.siemens.com/cs/ww/en/view/7302326
The attached pdf lists both MCs (Memory Cards, for older models) and MMCs (Micro memory Cards, for the newer models, see part numbers of the CPUs) https://support.industry.siemens.com/cs/ww/en/view/19102565
(Note: PG/PC is Siemens-talk for a programming computer) https://support.industry.siemens.com/cs/ww/en/view/12068554 Hope this helps, Daniel Chartier |

Thanks alot, Daniel. That really clarifies things for me, also thank you for the quick respond.
Is there any specific guidelines i should follow when i save my step 7 program to USB Stick for later use and download it back to step 7? |

Hello Retox; Sorry, it seems I had not really understood what you wanted to do. Tto send a project on your programming PC to a medium such as a USB drive, you should proceed to archive the project (the system will ask for a destination drive/directory when you create the archive). The nature, type and file extension of the archive will depend on the programming software you are using with the S7-300 project. It could be Simatic manager (Step 7 v5.5) or TIA Portal (Step 7 Basic, v11, v12 or v13). See the following extracts, use the applicable section:
https://support.industry.siemens.com/cs/ww/en/view/45531107 24.2 Archiving Projects and Libraries You can store individual projects or libraries in compressed form in an archive file. This compressed storage procedure is possible on a hard disk or on a portable data medium (such as a floppy disk). Archive Programs In STEP 7, you can use the archive program you prefer to archive projects. The archiving programs ARJ and PKZip ship with STEP 7 and are installed automatically. You will find the relevant descriptions in the installation paths of the archiving programs. To use a specific archiving program, you require the following version (or newer): • PKZip V12.4 (ships with STEP 7) • WinZip (tested with Version 14) • ARJ V2.50a (only for retrieving, ships with STEP 7 (not for Windows 7))
https://support.industry.siemens.com/cs/ww/en/view/109054417 Creating a project archive TIA Portal project archives are compressed files, each containing an entire project including the entire folder structure of the project. Before the project directory is compressed into the archive file, all files are reduced to their essential components to further decrease the size of the project. Project archives are therefore well suited for sending via e-mail. Project archives have the file extension ".zap[version number of the TIA Portal]". Projects created with TIA Portal V13 SP1 have the file extension ". zap13". To open a project archive, retrieve the project archive. By retrieving it, the archive file with the included project files is extracted to the original project directory structure. Once the archive is saved to your USB drive, you can retrieve it and open it (with the same software used to generate the archive) for download to another PLC (with similar configuration as the original machine).or modification. Hope this helps, Daniel Chartier |
