Storage of multilingual project texts
Different categories of texts are created when you configure a CPU, for example
●
Object names (names of blocks, modules, tags, etc.)
●
Comments (for blocks, networks, watch tables, etc.)
●
Messages and diagnostic texts
Texts are provided by the system, for example texts in the diagnostics buffer, or they are
created during configuration, for example, messages.
Texts exist in the project in one language or, after a translation process, in multiple
languages. You can maintain project texts in all languages available to you in the project tree
(Languages & resources > Project texts). The texts created during configuration can be
downloaded to the CPU.
The following texts containing the project data are downloaded to the CPU in the chosen
languages and are also used by the CPU display:
●
Diagnostics buffer texts (not editable)
●
Status texts for the module status (cannot be changed)
●
Message texts with associated text lists
●
Tag comments and step comments for PLC Code Viewer
●
Comments in watch tables
The following texts containing the project languages are also downloaded to the CPU in the
chosen languages, but are not used by the CPU display:
●
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 S7-1500R/H CPUs support archiving of multilingual project texts in up to three different
project languages. If the project texts for a project language nevertheless exceed the
memory space reserved for them on the SIMATIC memory card, the project cannot be
downloaded to 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.
Note
Size of the SIMATIC memory card
Make sure that there is enough available storage space on your SIMATIC memory card 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

You can find information on parameter assignment of multilingual project texts in STEP 7 in
the STEP 7 online help.
