How can you improve the performance in the SIMATIC Manager and in the STEP 7 project?
The table below describes a number of remedies for improving the performance in the SIMATIC Manager and in the STEP 7 project.
|No.||Causes and remedies for improving performance:|
|1||Influence of the size of the swap file (virtual memory) on the performance:|
Check the settings of the virtual memory in System Properties of your operating system. The Windows operating systems supported require additional memory on the hard disk (typically disk C:) for the swap file, depending on the memory expansion available. You should keep at least twice the size of the main memory free (recommendation: 1500 MB). Please also refer to the information in the readme file, section 3.2: Memory Requirements).
More information on setting the virtual memory is available in our Entry:
|2||Reorganize your STEP 7 project. This deletes the gaps in the program and compresses the project. This method reduces the project's memory requirement.
Save your STEP 7 project with "File > Save as..." and activate the option "With reorganization (slow)".
Change the project name or enter a new project name and acknowledge with "OK".
|3||Influence of the network environment on the performance:|
If you are working with one of the earlier versions of STEP 7, opening blocks, for example with STEP 7 version V5.1 in Windows 2000, can take longer than with the same project in Windows 98.
|4||Influence of the virus scanner on the performance:|
Each time a file is called the virus scanner is activated and requires time to check for viruses. It is a characteristic of STEP 7 to access numerous files that the scanner then blocks. Impairment of performance was found in the following constellations:
Please note the hardware requirements for your version of STEP 7. For example, for STEP 7 V5.4 your PC requires at least 512 MB RAM and a processor of at least 600 MHz. More information is available in the readme file, chapters 2 and 3 (hardware and software requirements).
|6||Compatibility with other SIMATIC software products:|
Please also note the compatibility of your version of STEP 7 with other SIMATIC software products. Information on this is available in our FAQ "Which SIMATIC software packages are compatible with which Microsoft Windows operating system and with STEP 7 V5.4?" in Entry ID: 18734363.
