The following texts containing the project languages are also loaded into the CPU in the
chosen languages, but are not used by the Web server:
● Comments in tag tables (for tags and constants)
● Comments in global data blocks
● Comments of elements in block interfaces of FBs, FCs, DBs and UDTs
● Network titles in blocks written in LAD, FBD or STL
● Block comments
● Network comments
● Comments of LAD and FBD elements
The CPU 1516pro-2 PN supports the storage of multilingual project texts in up to three
different project languages. The memory space reserved for this on the CPU must be
planned to be large enough. However, if the project texts in a specific project language
exceed the memory space reserved for them, you cannot load the project into the CPU. The
download is aborted with a notice that not enough memory space is available. In such a
case, take measures to reduce the required storage space, for example by shortening
comments.
The CPU 1516pro-2 PN has a reserved memory space of 7.5 MB for storage of multilingual
project texts. The CPU divides the available memory space between the selected project
languages because some languages require more memory space than others, for example,
Russian texts require more space than English texts. If you use only two project languages
instead of three, a memory space of 7.5 MB is available for two project languages instead of
three.
Note
Size of the SIMATIC memory card
If, when loading projects, the required memory space is more extensive/larger than the
memory space on the SIMATIC memory card used, the loading process into the CPU is
canceled. You receive an error message.
Ensure that your SIMATIC memory card has sufficient memory space for downloading
projects.
You can find information on reading out the memory usage of the CPU and the SIMATIC
memory card in the Structure and Use of the CPU Memory
(https://support.industry.siemens.com/cs/de/de/view/59193101/en) Function Manual.
You can find information on parameter assignment of multilingual project texts in STEP 7 in
the STEP 7 online help.
