General information on project loading

Introduction

To set up the automation system, you need to load the generated offline project data onto the connected devices. This project data is generated, for example, when configuring hardware, networks and connections or when programming a user programme or when creating recipes.

During the first download, the entire project data is downloaded. During subsequent loading operations, only the changes are downloaded.

You can download project data to devices and memory cards.

Note

Starting with TIA Portal V15 and the S7-1500 processor from software V2.5 onwards, the markup tables are included when downloading to the device or memory card and when downloading from the device or memory card. This ensures that the tag tables will also be available online on your processor. PLC tags are stored according to the tag tables configured offline. The device can perform an online/offline comparison and download the tag tables.

Note

During the compilation of the device, no additional download process can be started. Please note that the compilation process can not only be performed manually, but can also be started automatically for control and monitoring devices.

Possible download options

Depending on the object you want to retrieve, you have the following options:

  • Hardware and software (changes only)

    Both the hardware configuration and the software are downloaded to the destination if there are differences between the online and offline versions.

  • Equipment configuration

    Only the hardware configuration is downloaded to the destination.

  • Software (changes only)

    Only those objects that differ online and offline are downloaded to the destination.

  • Software (all)

    The PLC program containing all blocks, PLC data types and PLC tags is loaded into the target device and all values are reset to the initial values. Note that this also applies to retention values.

You can also transfer project data already on the device back to your project. You have the following options:

  • Upload the entire device as a new station

    The hardware configuration of the device and the software on the device are loaded in the project.

    All relevant device data is sent to the project.

  • Upload device software

    Only blocks and parameters from the device are sent to the existing processor in the project.

In both cases, when loading, all instances of the library types are re-linked to the correct version of the type in the project library. If the correct type is not yet available for the loaded instance or the correct version of the type does not exist in the project library, the type or version will be added to the project library.

Synchronised download

In team engineering, it is possible for several users to work on one project with several engineering systems at the same time and access one S7-1500 processor. To ensure consistency within a shared project, it is necessary to synchronise changed data before loading so that nothing is accidentally overwritten.

If differences are detected between online and offline data management in a joint project due to a different engineering system, automatic synchronisation of the loaded data is offered during loading.

In this case, the 'Synchronisation' dialog box displays the data to be synchronised with the current status (online-offline comparison) and possible actions.

Use case

Recommendations

Synchronisation

One or more blocks in the processor (online) are newer than in the engineering system (offline). These blocks need to be transferred from the processor to the engineering system before downloading. Automatic synchronisation is possible:

The blocks in the engineering system are updated before loading.

One or more new blocks have been created that only exist on the processor (online). These blocks need to be transferred from the processor to the engineering system before downloading. Automatic synchronisation is possible:

New blocks are added to the engineering system before downloading.

One or more blocks in the processor have been removed. Blocks must also be removed before downloading into the engineering system. Automatic synchronisation is not possible.

Blocks deleted on the CPU must be removed manually in the offline project in the engineering system.

One or more blocks in the processor and in the engineering system are different.

This happens when another user has changed the blocks where you have also made corrections and uploaded them to the CPU already.

These blocks with competing changes must be adjusted manually. In this case, you decide which changes you accept.

If blocks on the CPU are to be retained, they must be taken over from the CPU in the engineering system before being downloaded to the CPU.

If changed blocks are to be applied, you can continue the download without synchronisation.

Automatic synchronisation is not possible:

The affected blocks in the processor or in the engineering system must be adjusted manually. One of the existing versions of the block (online or offline) will be overwritten in the process.

There are differences in the hardware configuration of the processor (online) and the engineering system (offline). Differences in hardware configuration must be adjusted manually. In this case, you decide which hardware configuration you accept.

If the existing processor hardware configuration is to be retained, it should be applied to your engineering system before downloading.

If you want to use the changed hardware configuration, you can continue downloading without synchronisation.

Automatic synchronisation is not possible:

The hardware configuration must be adjusted manually.

One of the existing hardware configurations (online or offline) will be overwritten.

If necessary, you can use the 'Force download to device' command to download blocks without synchronisation.
