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 data blocks that are written in ladder logic (LAD), function block diagram
(FBD) or statement list (STL)
● Block comments
● Network comments
● Comments of LAD and FBD elements
The CPUs support archiving of multilingual project texts in up to three different project
languages. If the project texts for a particular project language nevertheless exceed the
memory space reserved for them, the project cannot be downloaded to the CPU. The
download is canceled with a notice that insufficient memory space is available. In such a
case, take measures to reduce the required storage space, for example by shortening
comments.
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 download to the CPU is canceled. You receive an error
message.
sure that there is enough available storage space on your SIMATIC
memory card for loading projects.
You will find information on reading out the storage space capacity utilization 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 will find information on parameterization of multilingual project texts in STEP 7 in the
STEP 7 online help.
