Siemens S7 1200 Upload and Download Completo
Step 7 Connecting, Downloading and Uploading
These are full general guidelines for connecting, downloading and uploading from an S7-300 or S7-400 PLC. The following procedures were created using Siemens SIMATIC Stride 7 version 5.4 software.
To start, open the SIMATIC Manager.
Now follow the links below.
Connecting to the S7 PLC
The Programming Cables
There are 3 major types of programming cables:
1. The CP5512 card in a PCMCIA slot.
2. The PC Adapter using a serial or USB connection
3. An Ethernet cable
The CP5512 card and the PC Adapter can communicate on either an MPI or PROFIBUS port. Note that PROFIBUS is labeled equally DP on the Siemens connection ports. These cables can piggyback on existing connectors. Be aware that the PC Adapter draws its power to work from the connection port so check the power LED for proper performance. The CP5512 menu draws its power from the computer.
For Ethernet (TCP/IP) use a standard Ethernet cable from the reckoner to a CPU with an Ethernet port, a CP 343/443 module or a network switch all ready attached to the PLC network.
Checking Communications
With the programming cable plugged in, y'all tin bank check for proper functioning by clicking on the Attainable Nodes icon.
If communications are successful, y'all'll see a window pop up similar to the one below. If so, and then close the Accessible Nodes window and proceed to the download or upload department.
If advice fails and then you lot volition receive a message like below.
This indicates that the cablevision is non in the right estimator port or the cablevision is not plugged in properly.
Setting the PG/PC Interface
In order to start advice to the PLC you will need to match the "PG Interface" setting with the programming cable and protocol. To do this, select the menu Options > Set PG/PC Interface.
The following dialog box volition open up displaying all the dissimilar interfaces (i.e. communication drivers).
Each cable has its own interface. For Ethernet select the TCP/IP interface for your computers network carte du jour. Be careful not to select your wireless Ethernet connexion.
To go information technology working quickly it is best to select the interface with the Car designation. This volition discover working settings and use them automatically.
For the PC Adapter click on the Properties button and make sure the Station Parameters Accost is a unique network address. It should not conflict with existing PLC and slave devices on the network. Besides, check under the Local Connection tab and make sure connection choice matches the port the cable is continued into.
Once the proper interface is selected and the properties are set then click OK and use the Accessible Nodes window to bank check for successful communications. It should work. If not double-check the connection and cable. With the CP5512 and PC Adapter cables, you should use the MPI port, every bit this is the default connectedness for Siemens.
If this doesn't piece of work then I don't know what to tell you.
Downloading
First, in order to enable the download menu commands, you lot must select the Block folder in the project'south station you wish to download.
At that place are three methods of downloading.
- Fractional download of selected blocks
- Full download of all blocks and system information
- Complete deletion of online PLC blocks and so downloading of all blocks and arrangement information
Partial Download
Fractional downloads are used in existing projects where only i or more blocks will be downloaded. To perform this type of download select the cake(due south) you wish to download and then select the PLC > Download menu item or the download button 
Holding down the Ctrl primal or the Shift key allows more then one block to be selected at a time. Be conscientious though as the social club of download volition occur in the society that the blocks were selected. This may hateful that an error volition occur if a block is chosen before it is downloaded.
The CPU will need to be in End manner before downloading the System Data Block (SDB) every bit this is equivalent to a hardware configuration download. This is normally not necessary in a PLC that has all gear up had its hardware configured. If you do download the system information, the post-obit messages will prompt you through the transitions.
If the CPU is in Run mode then y'all volition exist prompted to Stop the CPU. The software volition practise the Run to Cease transition when yous click OK.
After downloading the SDB you will be prompted to Run the CPU once more.
Clicking Yes will automatically put the CPU back into run mode.
Total Download
To download all the blocks at one time make certain you lot are in the Cake binder and select the Edit > Select All carte du jour particular. Click on the Download icon
Immigration the CPU Retention and then Downloading
The partial and total download methods above will overwrite existing blocks just will not any blocks from retentiveness. In guild to completely delete the existing plan in the CPU and download a new project select the Blocks binder and and so use the PLC > Download User Plan to Memory Menu carte du jour item.
The post-obit dialog box volition pop upward prompting y'all nigh the deletion of all the blocks and project data in the PLC. Click Yes to perform the functioning.
After this, follow the normal download procedure.
Uploading
In that location are ii methods for uploading. The first is when you have the original project and you want to preserve the symbols and comments. The second method, when you lot don't accept the original project, volition upload everything from the CPU but will take no associated documentation (i.due east. symbols and comments).
Uploading to an Existing Project
With the existing project open, select the View > Online menu item.
This is the same as the Online button on the icon bar.
This will open up upward another window called the Online Partner. It shows the existing blocks inside the CPU. The Online version is indicated past the highlighted title bar.
In that location is a connection betwixt these two versions and then that uploading from the online partner makes sure to preserve all the symbols and comments. Be careful. After uploading, brand sure to close the online partner and practise all work from the offline version.
To upload individual blocks, select them in the Online view and choose the PLC > Upload to PG menu item. For a full upload, select the Cake folder and do the aforementioned.
Upload without an Existing Project
Follow these steps when yous do non have the original project but wish to upload the program for backup purposes. With an existing project open up or a new bare projection select the PLC > Upload Station to PG… menu selection.
In the next screen, fill in the slot the CPU is in (this is always 2 for S7-300) and the node address of the advice port on the CPU. In the example beneath nosotros are talking to a CPU over MPI with node address 10.
After clicking OK, the whole contents of the PLC including all blocks and hardware configuration will be uploaded into a new station in the project.
While this project contains no documentation, it tin exist used equally a backup to download later if needed.
