A.2.6 STEP 7 reports "Out of memory space"
Query:
During the download of blocks to the Technology CPU, STEP 7 outputs the
message "The memory space in the module is not sufficient. Do you want to
compress the load memory?". The message persists after you compressed the
data and sufficient work memory is available.
Answer:
The cause of this message may be:
• The Technology CPU contains "orphan" technology DBs which are not listed in
your project. You can identify technology DBs based on the creation language
"TechObj".
To perform a corresponding check, open SIMATIC Manager and select View >
Details.
Delete all obsolete technology DBs from the Technology CPU.
A.2.7 The CPU goes into STOP sporadically as a result of time-out
Query:
You have tuned the system cycles; when operating in continuous mode, however,
the CPU sporadically goes into STOP because of a time-out at the integrated
technology.
Answer:
The system load on the integrated technology fluctuates, based on the command
volume and possibly occurring errors. Short system cycles may lead to time-out at
the integrated technology and, thus, to CPU STOP.
If this happens, extend the system cycles, so that the system does no longer
respond with time-out errors over a longer period of time.
A.2.8 Errors occur when the "Save and compile all" function is
executed for the technology data
Query:
Errors occur when the "Save and compile all" function is executed for the
technology data in S7T Config But I have only applied the default parameter
values?
Answer:
For reasons of safety, all safety- and function-relevant parameters or addresses
are assigned default values in S7T Config, so that the "Save and compile all"
function can not be executed.
This is why you should always exercise due care when setting safety- and function-
relevant parameters, and then verify their values and logical context.
