Siemens SIMATIC Step 7 Programmer’s Handbook
This handbook is a collection of programming overviews, notes, helps, cheat sheets and whatever that can help you and me program a Siemens PLC. I have to handhuch. The first thing I like to do with a new product is get handbbuch overview of everything. Getting used to part numbers and product groupings can go a long way with your comfort level. The best thing for this is the sales catalog ST 70 — You can also order a hard copy. What more could you want? These are very professionally done with a nice sounding narrator to take you through all the basics of the Step 7 software and hardware.
Of all the starting places to dig for more info I find the support section the best especially if you have a part number or key word you can search on. Clicking on the Product Support link will bring up a tree on the left hand side that hanrbuch be expanded down to the product of your affection.
Good luck and happy hunting. No support for multi-projects or HMI integration. No communication processors CP or function modules FM supported.
So there are quite a few major limitations with the Step 7 Hancbuch software which may end your further reading of this review. It has the same et2200s of programming functionality as the regular Step 7 packages plus some nifty interface enhancements to make it easier on the eyes and on the brain. Since the packages bear a lot of similarities it will also be easy for the student to transfer any learning on the Lite package over to STEP 7.
The overall aim of the Habdbuch package was to make the interface easier for new users. The added graphics and color are a welcome addition.
Another nice friendly feature is the extended hover help on the menus and icons where clicking on the tool tip expands it into more help text. On that note all the pop up hadnbuch are clearer then its STEP 7 counterpart. One of the major differences can be seen on the left hand side window. Pretty much everything the programmer needs for maintaining the project is neatly organized here.
On the right hand side is the old familiar tree structure of commands and blocks. The FC and FB blocks have been moved from here to a more logical place in the project window on the left hand side. The Project Window below it is great.
Something that just thrilled me is the tabs below that separate the offline and online versions et200w the program. On the regular STEP 7 software there is often a confusion between when you are offline or online. STEP 7 Lite minimizes that confusion by also provided clearly differentiated color schemes for when you have a block open online.
You can just hover the mouse over the symbol to get more detail. You can drag and drop then anywhere in the list. This could be really helpful for logically grouping blocks in larger projects. I also like the new way of creating blocks. Even the OB selection has a nice drop down box of all the OBs available with its symbolic name. The Hardware Manager The greatest change of all is the overhauled hardware manager.
The layout is great and is to be expected without the need to factor in networking. Just drag and drop your hardware on the picture and away you go. Much of the editor is like its big sister STEP 7. One part I like is a slight revamp of the declaration table. That means no having to dig through the tree just to see all the declaration variables.
Hopefully some of the better implementations will find there way into the STEP 7 software. One little caveat is that it kept crashing on my plenty beefy enough Windows XP Home computer. 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 operation.
The CP card draws its power from the handbuchh. With the programming cable plugged in, you can check for proper operation by clicking on the Accessible Nodes icon. If communications are successful, you’ll see a window pop up similar to the one below. If so, then close the Accessible Nodes window and proceed handhuch the download or upload section. This indicates that the cable is not in the right computer port or the cable is not plugged in properly.
In order to start communication to the PLC you will need to match the “PG Interface” setting with the programming cable and protocol.
The following dialog box will open up displaying all the different interfaces i. Each cable has its own interface. Be careful not to select your wireless Ethernet connection.
To get it working quickly it is best to select the interface with the E200s designation.
This will discover working settings and use them automatically. It should not conflict with existing PLC and slave devices on the network. Also, check under the Local Connection tab and make sure connection selection matches the port the cable is connected into. Once the proper interface is selected and the properties are set then click OK and use the Accessible Nodes window to check for successful communications. If not double-check the connection and cable.
First, in order to enable the download menu commands, you must select the Block folder in the project’s station you wish to download.
Partial downloads are used in existing projects where only one or more blocks will be downloaded. Holding down the Ctrl key or the Shift key allows more then one block to be selected at a time. Be careful though as the order of download will occur in the order that the blocks were selected. This may mean that an error will occur if a block is called before it is downloaded.
This is usually not necessary in a PLC that has all ready had its hardware configured. If you do download the system data, the following messages will prompt you through the transitions. The software will do the Run to Stop transition when you click OK.
Click on the Download icon. You will be prompted to overwrite any existing blocks and if you want to load the system data see above.
The partial and full download methods above will overwrite existing blocks but will not any blocks from memory. The following dialog box will pop up prompting you about the deletion of all the blocks and project data in the PLC. Click Yes to perform the operation.
There are two 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 don’t have the original project, will upload everything from the CPU but will have no associated documentation i. This will open up another window called the Online Partner. It shows the existing blocks inside the CPU. The Online version is indicated by the highlighted title bar. There is a connection between these two versions so that uploading from the online partner makes sure to preserve all the symbols and comments.
After uploading, make sure to close the online partner and do all work from the offline version.
For a full upload, select the Block folder and do the same. Follow these steps when you do not have the original project but wish to upload the program for backup purposes. In the next screen, fill in the slot the CPU is in this is always 2 for S and the node address of the communication port on the CPU. 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 can be used as a backup to download later if needed. System diagnostics, r eport system fault, integrated process fault diagnostics in S7-Graph. Have you suddenly found changes that have been made in the PLC but not in the offline program? Nobody knows what happened. The problems stem from the flexibility of the software both for downloading and editing the online program.
How to solve this problem? After that is a step by step best practice when editing programs. Offline program — The program that is stored on the hard disk of the computer. This will contain the documentation. Download — The act of taking the offline program on the computer and downloading it into the PLC. Upload — Taking the program in the PLC and bringing it up to the computer. Doing this without having the associated offline program open will cause a loss of documentation.
Save — Stores the open block onto the hard drive. Note that this only saves the opened block and not any others that are concurrently open. Nodes — Refers to any programmable device in our case a PLC in the network which will have its own unique address. The best practice is to make sure you are working from an offline file.
