The following are solutions for improving the performance of STEP 7 (TIA Portal) software and S7-1200/S7-1500 execution time.
[Control Technology] How to improve TIA Portal performance and S7-1200/1500 execution time?
The effect of the size of the swap file (virtual memory) on software performance
Please check the size of the virtual memory set in the operating system system properties. If there is available expanded storage space, the Windows operating system allows the swap file to use additional hard disk storage (usually a C drive). At a minimum, you need to ensure that virtual memory with twice the size of main memory is free.
Hardware and software requirements
Note that the hardware and software environment requirements for installing STEP 7 (TIA Portal) can be obtained by referring to entry 50204569.
Reduced software performance after configuring multiple SIMATIC controllers
After configuring a very large number of SIMATIC PLCs in a project, the software performance may degrade when you select a SIMATIC PLC in the project navigation bar.
Software performance after restarting the computer
When the STEP 7 (TIA Portal) software is run for the first time after the computer starts up, the software startup may take 1 minute or more. Open the STEP 7 (TIA Portal) software again and the start-up time will be significantly reduced.
Virus scan
If you install anti-virus software that is incompatible with STEP 7 (TIA Portal) software, the performance of the software may also be affected. The compatibility of STEP 7 (TIA Portal) and anti-virus software can be obtained through the compatibility tool. Compatibility tools are available under entry ID 67653438. For more information please refer to entry ID 37571060.
The S7-1200/1500 Programming Guide provides optimized programming recommendations and tips for the SIMATIC S7-1200/S7-1500 controllers. Differences in the system architecture of the SIMATIC S7-300/S7-400, as well as the associated new programming options, are clearly explained. These can help you create a standardized, optimally programmed automation solution. The described examples can be widely used on S7-1200 and S7-1500 controllers. The "S7-1200/1500 Programming Guide" is available under entry ID 81318674.
For the S7-1500, when the CPU transfers data to the data record, it should avoid accessing the data record via the web server at the same time. Otherwise, the CPU will greatly increase the time it takes to access the data record.
Limits the number of data records created by the "DataLogCreate" instruction. The amount of data that can be stored in the data record depends on the remaining size of the internal load memory space of the memory card or the CPU.
Application of laminator:
1. Geo-textile , compound geo-products, rough-surfaced geo-products
2. Construction and decoration, road and bridge construction, civil engineering and other fields.
3. One-layer lamination, double layer lamination or laminating combination of two or more layers of base materials.
4. Food, packaging, advertising, daily consumption, health care, medical industry and construction industry.
5. Shopping bags, food bags, raincoats and dust covers.
By accumulating nearly 20 years of experience in plastic machinery production technology and manufacture of hundreds of plastic machines, the company developed and produced geo-textile laminating/geo-membrane/sheet production line, waterproof sheet production line, car inner decoration & carpet/pad laminating line, etc. Our technical team has rich experience and high tackling capacity, and the equipment developed by the technical team has stable and reliable quality, excellent index and high flexibility, obtaining the approval and praise of users.
