Choose Create a new project and configuration. Warning Loss of data packets in the MPI subnet: Mahual 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.

Checking Communications With the programming cable plugged in, you can check for proper operation by clicking on the Accessible Nodes icon.

Therefore, communication variables in the user program must not exceed a length of 8 or 32 byte if data consistency is required. Figure shows the allocation of the interrupt inputs to the bits of the double word. We reserve the right to release product information for new modules or new module versions. Check the station name in the Station Configuration Editor.

The FC and FB blocks have been moved from here to a more logical place in the project window on the kfm hand side. The configuration is saved and the PC station is reconfigured. Click the General tab and press the Activate button. There is a connection between these two versions so that uploading from the online partner makes sure to preserve all the symbols and comments.

NetPro automatically starts, displaying the network configuration. The Address Registers Besides the regular accumulators, there are two bit manyal registers AR1, AR2 for storing pointers used in register indirect addressing methods.

You must take into account the operating system times of the CPU in question, the runtime of the user program and the extension of the cycle by active programming device functions, for example. This step involves using the Commissioning Wizard to configure the software you installed in the previous step. When allocating connection resources, you should observe the following points: The key can be removed in this position to prevent anyone not authorized to do so from changing the operating mode.

The CPUs provide connection resources for four routed connections. This means the address identifier used before the opening bracket is not needed if referencing a bit otherwise it will be a B for byte, W for word or D for double.

These notices are highlighted by the symbols shown below and graded according to severity by the following texts:! Create a function that will return the max number in the array and its position. With the programming cable plugged in, you can check for proper operation by clicking on the Accessible Nodes icon. Mode Selector Positions The positions of the mode selector are explained in the order in which they appear on the CPU.

Please consult the S Manual for further information! When working with indirect addressing it is sometimes needed to first of all open a DB and then begin working on the address without directly referring to any one DB. You can just hover the mouse over the symbol to get more detail. The OV bit is reset when the fault is eliminated. This is put on index 5. The Configuration Console should appear after terminating the Commissioning Wizard.

Downloading First, in order to enable the download menu commands, you must select the Block folder in the project’s station you wish to download.

The complete listing is also available as an Excel spreadsheet so you can sort or adjust to your needs. Click on the Download icon. Nodes — Refers to any programmable device in our case a PLC in the network which will have its own unique address. Follow these steps when 3144 do not have the original project but wish to upload the program for backup purposes.

The more modules you operate in the computer, the more steps are required. Using a Backup Battery or Accumulator You can start the Station Configuration Editor by double-clicking the icon. In Step 7 you can switch off automatic transfer of bus parameter.

Working from this window presents less of a danger for losing documentation but it is confusing and could lead to problems. When the power is on, the accumulator is recharged. Choose Network Save and Compile. The second method, when you don’t have the original project, will upload everything from the CPU but will have no associated documentation i.

CPU The variables of a user program with fixed preset values force values cannot be changed or overwritten by the user program. This completes the module configuration.

The Project Window below it is great. Here are some common mistakes and their warning signs. Transmission rates up to 12 Mbps are possible.
