ErrorID
Error message  Possible causes  To correct or avoid errors  Interrupts in
S7T Config* 
8005  Stack overflow  The command can not be 
executed, because all input 
buffer stacks are in use. 
Possible causes: 
•  The current commands are 
not executed in cyclic 
mode. This has the effect 
that stack memory is not 
reclaimed after the task is 
done. 
•  The S7 program transmits 
too many commands 
within a short period. 
•  An internal error has 
occurred in command 
execution 
Call the FBs in the cycle until one 
of the output parameters 
Done, 
CommandAborted or Error is 
TRUE. Verify that the program 
does not contain unnecessary 
(redundant) commands. 
30003 
8006  Insufficient memory  Integrated technology is out of 
memory. 
Reduce the number of technology 
objects or the number of 
interpolation points or polynomials 
in the cam disks. 
20002 
8008  Invalid technology DB 
(unknown GuID or 
InstanzID) 
The technology does not 
recognize this DB, because it 
has an invalid internal ID. 
Perhaps the DB was 
generated in a copy operation.
Recreate the DB in the 
"Technology Objects 
Management" dialog box, and 
download the configuration data 
again, i.e. establish online / offline 
consistency. 
8009  The technology DB is 
disabled because it 
was substituted with a 
new instance 
The DB is no longer assigned 
to the technology object, 
because a newer instance with 
a different DB number has 
been downloaded. 
Delete the DB   
800A  HW driver not 
available 
The driver of a physical device 
is not available or is being 
used by another TO. 
Check whether the logical device 
was available at the time the 
command was output, or whether 
it was being used by another 
technology object (TO). 
Connect a suitable device and 
check its functions, connections 
and terminals. 
Check the topology in HW Config.
Compare the configuration in 
HW Config and of the TO. 
20014 
8010  Drive failure  The drive or an external device 
has failed, or communication is 
disrupted as a result of faulty 
configuration or parameter 
data. 
Check the device functions, 
connections and terminals. Check 
the configuration in HW Config, 
based on the current telegram 
settings. 
20005 
8043 Illegal command 
parameter value or 
preset value 
One or several values at the 
input parameters of the FB for 
the command, or the preset 
values in relevant parameters 
are illegal. Example: 
•  The switching position of a 
cam is outside the 
operating range of the 
axis. 
Check the command and adjust 
illegal parameters. Note the 
current preset values.
