Emergency address (emergency IP)
The emergency address (emergency IP address) of a CPU is designed for diagnostic and
download functions, for example, if the CPU can no longer be reached via the IP protocol
because the wrong project has been loaded. You can find information on the emergency
address in the Communication
(https://support.industry.siemens.com/cs/ww/en/view/59192925) function manual.
Storing multilingual project texts
When you configure a CPU, different categories of texts are generated, 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 diagnostic buffer texts) or are created during
configuration (for example messages).
In a project, texts exist in one single language or in several languages after a translation
process. You can maintain project texts in all language available to you in the project tree
(Languages & Resources > Project Texts). The texts created during configuration can be
loaded to the CPU.
The following texts containing the project data are loaded to the CPU in the chosen
languages and are also used by the Web server:
• Diagnostic buffer texts (not editable)
• Module state texts (not editable)
• Message texts with associated text lists
• Tag comments and step comments for S7 GRAPH and PLC Code Viewer
• Comments in watch tables
The following texts containing the project languages are also loaded to 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 SIMATIC Drive Controller CPU supports the storage of multilingual project texts in up to
three different project languages. If the project texts belonging to a specific project language
nevertheless exceed the memory space reserved for them, the project cannot be loaded to
the CPU. The operation is canceled with a message indicating that not enough free storage
space is available. In such a case, take measures to reduce the required storage space, for
example by shortening comments.
You can find information on parameter assignment of multilingual project texts in STEP 7 in
the STEP 7 online help.
